PMMA is recognized as an optical polymer based on its refractive index (1.49). Hence, it is used in optical fibers.[1] It finds uses in biological applications because of its lower water absorption capability and biocompatibility.[2] The maximum moisture content of PMMA is 1.71% and SBF absorption is 1.96%. Simulated Body fluid test (SBF) is a method to identify the in vitro bioactivity of ceramic materials, by immersing the materials in an aqueous SBF solution. Application PMMA may be used as substrate for graphene growth.[3][4] Some studies report its use as PMMA-titania hybrid optical thins films[1] PMMA/polystryrene/clay nanocomposites[5] PMMA/polyurethane/carbon black nanocomposites for methanol fuel cells acrylic glass implant in surgical specialties as spacer.[6] |
