Poly(methyl methacrylate) (PMMA) has been used as a transparent material for various optical applications due to its high transmittance. However, PMMA has low thermal properties and high water absorption, which often causes deformations of PMMA-based materials. The deformation significantly decreases the light transmittance, limiting the use of PMMA in various applications. Herein, we synthesized four different series of PMMA-based random copolymers to enhance the thermal properties and reduce the water adsorption (e.g., N-phenyl maleimide, N-cyclohexyl maleimide, allyltrimethylsilane, and 2,2,2-trifluoroethyl methacrylate). Thermal properties were tested by measuring the glass transition temperature, thermal stability and coefficient of thermal expansion. Water absorption was measured through water contact angle. These copolymers are expected to resolve the limitations of conventional PMMA-based materials without the loss of transmittance (~90%). |
