摘要

In this study, a novel photo-crosslinked polymer composite was made from NCO-terminated fluoropolymers by the incorporation of functionalized graphene through the in situ polymerization method. This polymer composite can be photoinduced to form a network under UV radiation without photoinitiators, displaying an excellent transmittance (T%> 90% at 550nm), a high thermostability with a glass transition temperature (T-g <-15 degrees C), and a 10% weight loss temperature (410 degrees C). With UV radiation, the hybrid coating exhibited a controlled releasing force between 100 and 500g/25mm for silicone PSAs, which was an important breakthrough in the heavy-releasing industry. Their aging releasing performance and residual adhesion force were satisfactory. More importantly, antistatic agents are not needed any more before the coating of this novel releasing agent. In addition, the coating possessed good hydrophobicity with a contact angle of 110 degrees and great resistance to solvents. These metrics indicate that incorporating functionalized graphene as curable points into composites can greatly improve the performance of fluoropolymer properties. The obtained polymers have potential applications in the releasing and protective industry. (c) 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48322.
