Compared to petroleum oil, vegetable oil is one of the most widely used biomass because it is environmentally friendly and abundant in nature. In this study, vegetable oil was chemically modified through epoxidation and methacrylate reaction to convert it into a macromonomer capable of polymerization and crosslinking reaction. The resin for the reaction was composed of the macromonomer, a comonomer prepared by the reaction of HEMA and phthalic anhydride, photoinitiator, and solvent. The crosslinking reaction was carried out through UV irradiation of 370 nm, and it was converted into a crosslinked product after 3 to 20 minutes. Then, a porous polymer film was prepared through a phase separation process utilizing solvent-non-solvent exchange. In this process, various variables that can affect the porous structure were investigated and the mechanical properties of the porous film were evaluated. |
