PMMA/HA (Hydroxyapatite) composites have been used in biomedical applications such as dentistry, orthopedic retainers, and bone replacement. It is used as substrate for graphene growth.
Some studies report its use in
PMMA-titania hybrid optical thins films
PMMA/polystryrene/clay nanocomposites
PMMA/polyurethane/carbon black nanocomposites for methanol fuel cells

General description

Poly (methyl methacrylate) (PMMA) is an amorphous transparent thermoplastic polymer. PMMA is recognized as an optical polymer based on its refractive index of 1.49. Hence, it is used in optical fibers.It finds uses in biological applications because of its lower water absorption capability and biocompatible.The maximum moisture content of PMMA is 1.71% and SBF absorption is 1.96%.Simulated Body fluid test (SBF) is a method to characterize the in vitro bioactivity of ceramic materials, by immersing the materials in an aqueous SBF solution.
