General description
Poly (methyl methacrylate) (PMMA) is an amorphous transparent thermoplastic polymer. PMMA is recognized as an optical polymer based on its refractive index (1.49). Hence, it is used in optical fibers. It finds uses in biological applications because of its lower water absorption capability and biocompatibility. 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. Some studies report its use as
- PMMA-titania hybrid optical thins films
- PMMA/polystryrene/clay nanocomposites
- PMMA/polyurethane/carbon black nanocomposites for methanol fuel cells
- acrylic glass
- implant in surgical specialties
- as spacer.
