Preparation and properties of UV‐curable fluorinated polyurethane acrylates containing crosslinkable vinyl methacrylate for antifouling coatings

Abstract

To obtain highly effective antifouling coatings, a series of UV-curable polyurethane acrylates containing diluents [heptadecafluorodecyl methacrylate (PFA, 6 wt %)/isobornyl acrylate (IBOA, 34 wt %)/methyl methacrylate (MMA, 20-5 wt %)/vinyl methacrylate (VMA, 0-15 wt %)] were prepared. This study examined the effect of bulky MMA (20-5 wt %)/crosslinkable VMA (0-15 wt %) weight ratio on the properties of the UV-curable polyurethane acrylates. The fluorine concentration in UV-cured film surface increased with increasing VMA content up to 9 wt % and then decreased. The T ga , transparency, elasticity, and mechanical properties of the UV-cured film samples increased with increasing VMA content. The water/methylene iodide contact angles and surface tension of samples increased from 107/79 to 121/91 and decreased from 17.8 to 12.7 mN/m with increasing VMA content up to 9 wt % and then decreased/increased, respectively. From these results, it was found that the optimum VMA content was 9 wt % to obtain a highperformance antifouling coating.

UV LED Curable Perfluoropolyether (PFPE)-Urethane Methacrylate Transparent Coatings for Photonic Applications: Synthesis and Characterization

“…Owing to their unique properties ranging from high thermal and chemical resistance [ 1 , 2 , 3 ], low surface tension [ 4 ], low refractive index and transmittance losses [ 5 , 6 ], large thermo-optic coefficients [ 7 ], and color stability [ 8 ], UV-curable fluorinated resins are the preferred selection in several industrial and commercial applications. In addition to integrated optical devices, cladding for optical fibers, photovoltaics, and microelectromechanical system (MEMS) devices, other applications such as marine antifouling coatings [ 9 , 10 ], automotive clear coat formulations [ 11 , 12 ] and batteries [ 13 , 14 ], coatings of biomedical devices (e.g., artificial hearts, vascular prostheses or catheters) [ 15 ], microfluidic devices [ 16 , 17 ], textile industry, food packaging [ 18 ], etc., were also suggested.…”

A New Strategy for the Synthesis of Fluorinated Polyurethane

“…Fluorocarbon chains or groups have been incorporated into polyurethanes by fluorinated chain extenders, [17,18,19,20,21] diisocyanates, [22] glycols, [23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41] side groups/chains [42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58], and end-cappers [59,60,61,62,63,64,65,66]. In 2005, for the first time, a novel fluorinated polyurethane based on polyurethane macromonomers partly acrylate-endcapped with hexafluorobutyl acrylate was synthesized through macromonomer radical copolymerization [17].…”

Investigation of Mechanical, Surface and Thermal Properties of Dual-Curable Hydrophobic Coatings

“…Bu nedenle, florokarbon kaplamalar, düşük sürtünme direnci, su ve yağı sevmeme, yanmazlık, iyi yalıtım ve gaz bariyer özellikleri gibi önemli özelliklere sahiptirler. Bu özelliklerle birlikte floropolimerler; biyomedikal cihazlar, optik fiberler, yakıt hücreleri, gelişmiş tekstil ürünleri gibi birçok farklı kullanım alanına sahiptir [14][15][16][17][18].…”
