Abstract
A photocurable composition can comprise a polymerizable material and a photoinitiator, wherein the polymerizable material may comprise 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; and R2 being —CH═CH2 or —CCH3=CH2 covalently bonded to Ar; y being 1-4.

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.
A method of forming a photo-cured layer on a substrate, comprising:
- applying a layer of a photocurable composition on the substrate, wherein the photocurable composition comprises a photoinitiator and a polymerizable material, the polymerizable material comprising 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;
- bringing the photocurable composition into contact with a template or a superstrate;
- irradiating the photocurable composition with light to form a photo-cured layer;
- and
- removing the template or the superstrate from the photo-cured layer.
