Transparent PMMA films toughened via in-situ solution copolymerization for potential application as protective film in polarizer
In this work, free radical solution polymerization was used to prepare polymeric nanocomposite films by copolymerization of flexible butyl acrylate (BA) monomer and modified nano−silica with methyl acrylate (MMA) monomer. Our findings showed that the addition of BA monomer and nano−silica had limited effect on the transmittance of PMMA films, and the transmittance could achieve as high as 93%. Perfect overall properties of the as−prepared films (with a tensile strength of 36 MPa and an elongation at break of 42%) could be achieved when the monomer MMA:BA was set as 6:2 at a nano−silica content of 20 wt%. The PMMA−based nanocomposite films prepared in this work possessed excellent transparency, desired toughness and good hydrophobicity, which made them potentially promising for the applications as protective films for polarizing films.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including:
