Rubber is one of the most commonly used industrial materials worldwide. However, there is a gap in the literature on the production of rubber thin films in nanoscale. When the rubber thin films are produced in nanoscale, they can be used in high-tech applications where bulk rubbers have never been used before. This study is one of the first investigations to focus on the vapor-based production of the polyisoprene (PI), which is an important member of the synthetic rubber class. For this purpose, a single-step, rapid and environmentally friendly method based on plasma enhanced chemical vapor deposition (PECVD) was employed to produce PI thin films using 2-methyl-1,3-butadiene (isoprene). The high-vapor pressure of isoprene makes it a promising monomer for the production of chemical vapor deposition polymers. The effect of plasma processing parameters on the PI deposition rate was investigated. The deposition rate of PI thin film as high as 40 nm/min was achieved and the contact angle of PI coated bamboo surface was found to be 146.8. The mechanical durability and laundering tests of PI thin films were performed. Based on this study results, PI thin films produced by PECVD can be used in a number of potential applications.

“…This is usually enhanced by adding other components to the polymer coating. Usually the acrylic polymers (such as Paraloid B-44) are used to increase the adhesion on the substrate, but the low chemical reactivity of PVDF makes its application difficult [42][43][44][45]. Another problem encountered with fluoropolymers is These experiments evidenced that PropS-SH can penetrate better into the metal when applied by spraying, homogeneously covering the surface, whereas Incralac does not show these properties.…”

Recent Advances in Protective Coatings for Cultural Heritage–An Overview

et al. 2020

View full text Add to dashboard Cite

In the last decades, the interest in the development of protective coatings for movable and immovable Cultural Heritage (CH) assets has decidedly increased. This has been mainly prompted by the raising consciousness on preservation requirements for cultural artefacts and monuments, which has consequently determined the development of new protective products. From acrylic resins used at the end of the last century to the up-to-date biomaterials and nanoparticles employed nowadays, the research has made a giant step forward. This article reviews the progresses, the technical challenges, and the most recent advances in protective coatings for archaeological metal, glass, and stone artefacts. It aims at offering a comprehensive and critical overview of the progressions in conservation science and displaying how research has optimized polymers in order to solve deterioration problems. Attention is given to recently developed materials, hybrid coatings, and corrosion inhibitors. This work seeks to provide a reference point for future research and to offer a wide-ranging introduction on the newly available material technologies to restorers and conservators.

“…Often these products are combined in double-layer systems to enhance their protective actions (such as Incralac ® and wax) [9]. Fluoropolymers have also been used because of their high resistance to ultraviolet exposure degradation [10]. Alternatively, safer coatings consisting of renewable polysaccharides such as chitosan (CHT) [11], benzotriazole (BTA) end-capped poly(lactic acid)s [12] as well as hybrids coatings consisting of siloxane domains embedded in polymeric phases [13] have been recently investigated.…”

The synergistic effect of an imidazolium salt and benzotriazole on the protection of bronze surfaces with chitosan-based coatings

et al. 2020

The class of imidazolium salts contains effective anticorrosion additives for metal substrates. This study evaluated the potential of 1-carboxymethyl-3-methylimidazolium bis (trifluoromethylsulfonyl) imide (HO 2 CC 1 MImNTf 2) for application in cultural heritage, exploring it as anticorrosion additive in chitosan-based coatings for the protection of copperbased alloys. Under accelerated corrosion conditions with HCl vapor, the chitosan coating with HO 2 CC 1 MImNTf 2 was less effective than the one with benzotriazole. The coating with a combination of HO 2 CC 1 MImNTf 2 and benzotriazole resulted in the optimal protective efficacy of the bronze surface, and it also maintained high transparency without changing the bronze appearance.
