“…It should be pointed out that the repeated mechanical flexibility performance of BHC/AgNW/THC TCF was still better than that of AZO/AgNW/AZO TCF with a sandwich structure [17]. UV curing acrylic resin coatings on the surface of thin films are commonly used to enhance the hardness and abrasion resistance of thin films, but the introduction of hardening coatings usually affects the flexibility of thin films [25]. Therefore, how to optimize the composition of UV ink and balance the relationship between film hardness and flexibility needs further research.…”

A sandwich-structured bottom hard-coat/silver nanowire/top hard-coat (BHC/AgNW/THC) transparent conductive film (TCF) has been prepared by embedding the functional AgNW layer between two HC layers. The BHC/AgNW/THC TCFs show high scratch resistance with a hardness of 3H due to the enhanced adhesion to the substrate. In addition, the BHC/AgNW/THC TCFs exhibit a transmittance of 90.6% and a haze of 1% at 550 nm under a sheet resistance of 72 Ω/sq. Furthermore, highly enhanced long-term stability has been guaranteed by the HC layers due to their excellent gas barrier property. The amazing fact is that hard coating has little effect on the flexibility of AgNW films especially under extreme bending conditions and negligible resistance change could be observed after bending over thousands of times. Consequently, the greatly improved performance of BHC/AgNW/THC TCFs provided by employing hard coating layers paves the way for real-world applications of flexible AgNWs in vast areas that rigid indium tin oxide is not suitable.

“…In a research on UV cured coatings done by Salleh and co-workers, it was demonstrated that increasing in silica content of the coating improved its scratch resistance (Salleh et al 2009). This modification also led to an increase in hardness.…”

Polymers are chemical compounds or mixture of compounds consisting of repeating structural units created through a process known polymerization. These are important groups of materials made up of long chain carbon, covalently bonded together. Polymerization is a process in which monomeric molecules react together chemically to form macromolecules. Polymers are now finding increasing use in engineering applications due to unique properties. Mechanical strength of polymers is of prime importance in engineering applications. Polymers in their service life are exposed to different mechanical and thermal stresses. Durability of polymer strongly depends on the resistance of these materials against environmental condition. In order to assess the strength of material, good knowledge on mechanic of materials is imperative. In this manner, this section aims at introducing mechanical properties of polymers.

“….. That is why the use of a protective coating is required. To go further into a sustainable development approach, such coatings can be photo-cured [1][2][3][4][5][6][7][8][9]. Indeed, photo-polymerization is an environmentally-friendly technique, since it allows to work with mixtures containing no solvents, curing them at a very high rate, and it is an energetically economic process.…”

“…Nevertheless, the damage resistance of UV-curable, 100% solids organic coatings is often not sufficient and many studies in the literature report the incorporation of nanoparticles in the systems. Nanosilica and nano-alumina are commonly used to improve the scratch or abrasion resistance of coatings [1,[3][4][5][7][8][9]18], since they are high hardness materials (respectively, 7 and 9 on the Mohs' scale).…”

International audienceThe relationships between the composition and the scratch resistance of clear photo-polymerized protective coatings for thermoplastic substrates were studied in relation with their thermomechanical properties. For this purpose, dynamic mechanical analyses of free-standing films were compared to micro-scratch tests of thick or thin coatings deposited on polycarbonate. In these experiments, the depth indented by the tip, the elastic recovery of the material, the residual depth of the scratch, and the load at which the first crack appears, were analyzed. Different coatings close in formulation were studied. First, the proportion of a specific difunctional monomer featuring a hard structure was varied in order to change the crosslinking density of the polymer network. The thermomechanical properties were consequently modified at high temperature, but remained similar at 23 degrees C, whereas at this temperature, the scratch properties of the coating evolved with its composition. The addition of 5 wt% alumina or silica nanopartides did not modify the thermomechanical properties or the scratch resistance of the coatings, even if a more concentrated filler layer was observed near the surface of the coating. Nevertheless, the consequent incorporation of a new diacrylate monomer in the polymer matrix delayed the ductile-brittle transition. Finally the substitution of petro-based monomers by slightly different bio-based compounds led to a change of the scratch behavior of the thickest coatings (150 mu m-thick), and increased the critical load for the thinnest coatings (15 mu m-thick). It comes out that micro-scratch tests allow a finer comparison of the samples
