ABSTRACT
The silicone monomer (SiH2) used in this study contains acrylate monomer, DMA (n,n-dimethylacrylamide). For the polymerization, PtOEP (platinum octaethylporphyrin) was added to the synthesized silicone, DMA (n,n-dimethyl acrylamide), HPMA (hydroxy propyl methacrylate), PEGMEMA [poly(ethylene glycol) methyl ether methylacrylate], EGDMA (ethylene glycol dimethacrylate) and the initiator AIBN (azobisisobutyronitrile) with various concentrations. Using the polymer produced through the thermal polymerization process, the optical and physical characteristics of high performance silicone hydrogel lenses were measured. The water content of sample containing PtOEP was in the range of 65.21â¼66.56%. And also, oxygen permeability (Dk) of sample containing PtOEP was in the range of 30.20â¼30.85 × 10-11 cm²/sec × mlO2/ml × mmHg. In case of the sample with nanoparticle, the oxygen permeability was higher than that of Ref. sample without nanoparticle. Silicone hydrogel monomer containing PtOEP was expected to be used usefully as a material for red tinted chromagen optical lens with high oxygen permeability for color amblyopia.
