AI Technical Summary

Technical Problem

Existing soft contact lens materials suffer from problems such as water evaporation, dry eye syndrome, bacterial growth, and protein and lipid adsorption, making it difficult to achieve a balance between low water content, high oxygen permeability, softness, and toughness, and the surface coating is not easy to bond.

Method used

Silicon polymer materials were prepared by the synergistic effect of three silicon monomers: short-chain aliphatic silicon monomers of acrylate or acrylamide, long-chain polysiloxane monomers of acryloyloxy or acrylamide, and aromatic silicon monomers of styrene, combined with compression molding and covalent crosslinking, to prepare silicon polymer materials suitable for surface coating.

Benefits of technology

A silicon polymer material with low water content, high oxygen permeability, softness and moderate toughness has been developed. It has anti-protein and lipid adsorption properties and is suitable for ophthalmic lenses, especially low water content soft contact lenses for correcting refractive errors in the human eye.

Abstract

The present application relates to a silicon polymer material, which is polymerized from silicon monomers, the silicon monomers comprising at least a first silicon monomer, a second silicon monomer and a third silicon monomer, wherein the first silicon monomer is selected from short-chain aliphatic silicon monomers, the second silicon monomer is selected from long-chain polysiloxane monomers, and the third silicon monomer is selected from aromatic silicon monomers, and the weight ratio of the first silicon monomer: the second silicon monomer: the third silicon monomer is (30-70):(20-60):(0.05-10). The present application also relates to a medical device prepared from the silicon polymer material and a preparation method thereof.
