1. A photocurable composition comprising a polymerizable material and a photoinitiator, wherein the polymerizable material comprises at least one first polymerizable monomer having a structure of formula (1): (R1)x—Ar—(R2)y (1), with
Ar being one or more substituted or unsubstituted aromatic rings;
R1 being a structure covalently bonded to Ar including at least one acrylate group; x being 1-4;
R2 being —CH═CH2 or —CCH3═CH2 covalently bonded to Ar; y being 1-4,
and wherein an amount of the at least one first polymerizable monomer is in a range from 50 wt % to 100 wt % based on the total weight of the polymerizable material.
