Researchers found that the damage morphology of thick multilayer protective systems under impact loading shows specific patterns.

The response of organic coatings to mechanical impact is crucial to their corrosion protection performance, particularly under offshore conditions. The paper categorizes and discusses four different types of response during the high-energy (3 to 20 J) impact of a falling ball-shaped weight on 14 multilayer organic offshore coating systems. The response types include plastic deformation, brittle (compressive) crushing, radial crack formation, and lateral delamination. Threshold and transition conditions are analyzed based on contact mechanics relationships.

Reading tip: Corrosion protection coatings

The book “Anticorrosive Coatings: Fundamentals and New Concepts” brings together all the disciplines involved in the creation and use of corrosion protection coatings for metals. It presents the latest insights into the quality and chemistry of surfaces, the proper way to prepare them by conversion treatment, the function of resins and anticorrosion pigments in paints, and novel concepts in corrosion protection. As an added bonus, all the standards and directives mentioned in the text are grouped together in their own chapter for a better overview.

For the first time, complete force-deflection curves for this type of coating are recorded with an instrumented impact tester. The curves feature four characteristic points, namely a first local force maximum (F_FS), the respective deflection at this force level (δ_FS), a maximum force (F_max), and the respective deflection at this maximum force (δ_max). These characteristic parameters are discussed in terms of coating system composition. Empirical equations for these parameters as well as for the damage size are derived. The results offer opportunities to quantitatively rank organic coatings with respect to their impact resistance.

A recently published review highlights the most important advances in the development and manufacture of advanced hybrid polymer-inorganic layered anticorrosion coatings for marine applications.

These newly hybrid anticorrosion systems are gaining importance with the premise to improve the efficiency of the widely employed pure organic coatings, while widening the available types of polymeric materials employed. These could give rise to innovative high protective coatings with improved characteristics (mechanical strength, conductivity, biodegradability) or secondary functionalities (self-healing, anti-fouling).

Graphene-based anticorrosion nanocomposites

In the review, four aspects are mainly overviewed, first, the use of 2D-layered inorganic fillers in coatings based on a barrier-type protection anticorrosion mechanism, with a special focus on graphene and its derivatives. Second, different modification strategies are presented, including covalent and non-covalent, always aiming to increase the compatibility between filler and matrix that would give as a result more efficient systems, due to 2D-layered fillers biggest drawback, their tendency to agglomerate.

Third, different multi-functionalising opportunities that graphene and its derivatives have to offer when introduced to these systems are reviewed, presenting some of the latest works reported in the past 2 to 3 years, while reviewing alternative layered structures such as natural clays or layered double hydroxides with their modifications. Fourth, different possibilities for multifunctioning these systems and their compatibility with graphene-like fillers are discussed. Finally, the conclusions and future perspectives on graphene-based anticorrosion nanocomposites are presented.

The review has been published in Progress in Organic Coatings, Volume 163, February 2022.

Conference tip

The European Coatings Webforum Protective Coatings on 08 and 09 March focuses on anti-corrosive and protective coatings. Among other things, the virtual event offers insights into the latest developments in binder, additive and pigment technology.

Covestro has broken ground in Antwerp for a new production facility for the manufacture of aniline. With the capacity expansion, the company intends to strengthen its European production network for the foam component MDI.

According to the company, Covestro is investing more than EUR 300 million. The new aniline plant is scheduled to be operational – depending on the volatile economic situation – in early 2025. This will create around 40 new jobs. The basic chemical aniline is an important starting material for many chemical products, including the rigid foam component MDI. The product is mainly used for the production of insulation materials for buildings and refrigeration equipment.

Increased energy efficiency

As Covestro communicates, the new plant will use state-of-the-art technologies that will help to significantly increase the energy efficiency of production in Antwerp. Currently, around 20 percent of the steam required on site is covered by using process heat generated during production. The remaining steam is generated using fossil resources. With the commissioning of the new plant, the share of steam generated from process heat is intended to double to 40 percent of local demand, and the use of fossil fuels will decline.

Despite OGC Nice President Jean Pierre Rivère stating otherwise, Lyon President Jean Michel Aulas believes that Hatem Ben Arfa wants to join Lyon but that Leicester City are currently in pole position to land the player.

Speaking to Canal + this evening, Aulas discussed the French international’s future:

“Ben Arfa, it is a question of passion. He is close to our desire, our enthusiasm, to our fans. I think that he really wants to join Lyon. If he does not come, it will be for reasons that have nothing to do with passion. I believe that it is more Leicester City in terms of the direction he is heading. That is what people have told me who spoke to him on the phone this afternoon.”

A full report on Ben Arfa’s future to follow this evening.

Researchers have developed eco-friendly cellulose acetate films incorporated with Burdock (Arctium lappa L.) root extract.

In the present work, a new active film based on cellulose acetate (CA) and Burdock (Arctium lappa L.) root extract (BE) was developed and the effect of different BE concentrations (0, 0.3, 0.6 and 0.9 wt%) on the mechanical, physic-chemical, thermal, antimicrobial and optical properties of CA film were investigated. Results indicated that the antimicrobial activity of CA against Aspergillus niger, Candida albicans, Staphylococcus aureus and Escherichia coli improved with increasing BE concentration. Also, there was an increase in free radical scavenger activity, total phenol content, elongation to break, contact angle, colour difference and water vapor transmission rate with BE concentration increasing. While, Young’s modulus, tensile strength, solubility, Water content, and swelling decreased compared to control film (0 % BE).

Environmentally friendly edible film

The porous and non-uniform surface in the films was observed with increasing BE concentration by a scanning electron microscope. Fourier transform infrared spectroscopic analysis showed that by BE adding to CA film, insignificant changes occurred compared to control film. Differential Scanning Calorimetry results indicated that melting temperature and the glass transition temperature of CA films were decreased with BE increase. CA Film with 0.9 % BE had a 99 % weight loss after 60 days. The current research concludes that CA film containing BE can be used as an active, biodegradable and environmentally friendly edible film for food packaging.

The study has been published in Progress in Organic Coatings, Volume 186, January 2024.
