“…In addition, much lower values were recorded on the PDMS surface for both RMS (0.055 µm) and peak-to-valley difference (2.989 µm), indicating that the PDMS surface is smoother and exhibits less variability than the HPS surface. Sobhani [ 51 ] studied the mechanical and surface properties of HT-PDMS elastomer and reported an RMS value between 0.049 and 0.054 [µm], indicating minimal roughness due to the particles present on the surface. Dopilka [ 52 ] reported an RMS value of 0.030 [µm] for a thin PDMS silicone film.…”

Edible composite coatings (ECC) formulated from biopolymers that incorporate antioxidant molecules represent an innovative alternative to improve food texture and provide health benefits. Tannins have aroused great interest due to their ability to stabilize suspensions and counteract the effects of free radicals. The mechanical and surface properties are crucial to establishing its quality and applicability. In this study, the objective was to analyze the mechanical and surface properties of ECC made with nanoliposomes that encapsulate grape seed tannins (TLS) and polysaccharides such as hydroxypropylmethylcellulose (HPMC) and kappa carrageenan (KCG) for their future direct application in foods susceptible to oxidation. The inclusion of HPMC or KCG affected the density, showing values in the range of 1010 to 1050 [kg/m3], evidencing significant changes (p < 0.05) in the surface tension in the TLS/FS-HPMC and TLS/FS mixtures. KCG and in the dispersion coefficients, with values in the range of −2.9 to −17.6 [mN/m] in HPS (S1) and −17.6 to −40.9 [mN/m] in PDMS (S2). The TLS/FS-HPMC coating showed higher stiffness and elastic recovery capacity than the TLS/FS-KCG coating, suggesting that the presence of TLS influenced the stiffness of the polymer. HPMC is recommended as a suitable polymer for coating solids, while KCG is more appropriate for suspensions. These findings provide valuable information for directly applying these ECC compounds to food products, potentially offering better preservation and health benefits.

“…In this work, a PDMS/ BaTiO 3 composite material was chosen for energy harvesting applications due to PDMS’s polymer elastomeric properties and high flexibility, 30 as well as BaTiO 3 ’s excellent dielectric and piezoelectric properties. The casting process is performed because of the simplicity and efficiency of the method, allowing for the development of flexible composite generators.…”

“…30 Despite having icephobic properties, PDMS-based materials are not commonly used in most industrial and marine applications because of their poor mechanical resistance to abrasion. 31 More robust materials such as epoxy resins, characterized by excellent thermal properties and good resistance to abrasion, are required for use in outdoor applications such as harbor structures. 32 However, although epoxy-based coatings present a high Young modulus of around 3.8 GPa, 33 they are brittle and show poor hydrophobicity and icephobicity.…”

This study details the fabrication of an icephobic coating for steel produced using a silicone-epoxy hybrid resin; the coating has good mechanical properties and weathering resistance for outdoor applications. Silicone-epoxy hybrid resins and amino-functional silane-curing agents were selected for investigation and applied to steel samples. Wettability, ice adhesion strength, and the mechanical and weathering resistance properties of the developed coatings were assessed using a drop-shape analyzer, Fourier transform infrared, X-ray photoelectron spectroscopy, as well as push-off, tensile, and QUV tests. The possible correlation between ice adhesion strength and Young modulus was also investigated. The best-performing matrix in terms of mechanical properties and weathering resistance had its surface energy characteristics alteredvia two fluorinated silicone additives at various concentrations-to lower ice adhesion strength. For the steel substrates, the optimized additive-altered surface showed a lower ice adhesion strength (decreasing from 362 to 94 kPa) with an adhesion reduction factor of 10.6. The fabricated coatings can serve as a protective layer for marine harbor infrastructures.
