• W2183464858 abstract "Numerous possibilities of biological systems to adapt to various external factors have motivated researchers to create new types of materials capable of adjusting to different environmental conditions by manipulation of structural rearrangement on the surface and in bulk. Such “smart” materials offer opportunities for the development of polymer films and coatings with adaptive surfaces. Various functional components and approaches were used in this work to fabricate elaborate polymer surfaces with specific properties, such as hydrophobicity, oleophobicity, reduced light reflection, and increased light transmission. The self-assembling of block copolymers or patterning of UV-curable materials are low-cost and effective methods for producing functional surfaces. In order to make polyurethane (PU) hydrophobic, it was modified with polydimethylsiloxane (PDMS) or fluorocarbon (PF) end groups using a transurethanetion reaction without applying hazardous isocyanates. Surface properties of copolymer films were controlled with the hydrophobic-end components which have a tendency to segregate on a polymer film–air surface owing to their low surface energies. Improved hydrophobic properties of modified PU films were achieved due to the spherical microstructure formation caused by the self-assembly of block copolymer and the strong surface segregation of PDMS or PF components upon exposed to air environment. UV-curable urethane acrylates consisting of siloxane or fluoro components were applied for the fabrication of microstructured coatings using a micropatterned mold. The micropillars that formed were elongated in a controlled stretching procedure. These micropillars were the reason for the enhanced superhydrophobicity of the coatings, verified by the static water contact angles (CA). The dynamic CA results with oleic acid clearly indicate that the chemical composition of the bulk coatings is also an important factor for achieving superhydrophobicity and lipophobicity, including low CA hysteresis. UV-curable urethane acrylates were also used to fabricate transparent nanocoatings that have pillar or pit features, using nanopatterned molds in a UV-molding method. Wettability studies with static and dynamic CAs of water and oleic acid showed that the hydrophobicity and oleophobicity of the coatings increased owing to the nanostructuring and modification with a low surface energy fluorosilane. The square gratings with dimensions below the wavelength of visible light provided anti-reflective properties on an anti-wettable surface. Both grating features of the nanocoatings had a low reflection over the visible spectrum, demonstrating broadband antireflection." @default.
