Analysis of Physical and Antibacterial Properties of Functional Silicone Hydrogel Ophthalmic Lenses Containing Graphene Groups

The physical and antibacterial properties of ophthalmic lenses fabricated by copolymerization with hydrogel monomers using two types graphene were measured, their usability as contact lens materials was analyzed. For polymerization, silicone monomers, including SID-OH, 3-(methacryloxy)propyl tris(trimethylsiloxy)silane, decamethylcyclopentasiloxane, used, N,N-dimethylacetamide, ethylene glycol dimethacrylate a crosslinking agent, azobisisobutyronitrile an initiator added. Also, oxide nanoparticle (GON) nanoplate (GNP) used additive, the after evaluated. satisfied basic general showed characteristics high water content, disadvantage very weak durability, due to low tensile strength. However, it confirmed that strength greatly improved adding GON GNP. With GON, oxygen permeability refractive index slightly improved. Therefore, determined in this study can be various ways material.
