The effect of incorporation of nanofillers (montmorillonite, silica, hydroxyapatite) and bioactive glass (BG) microparticles into a silicone elastomer matrix, on its thermomechanical properties and bioactivity was investigated. The obtained samples were characterized using differential scanning calorimetry and dynamic mechanical analysis, as well as by hardness, tensile, and tear testing, whereas their bioactivity was evaluated by immersion of specimens into simulated body fluid solution and by cell culture experiments (fibroblasts and osteoblasts). Montmorillonites and especially Cloisite 20A have been shown the most efficient reinforcement for improving mechanical properties of silicone rubber composites. On the other hand, BG and silica hybrids exhibited significant bioactive properties. POLYM. COMPOS., 39:2560–2570, 2018. © 2016 Society of Plastics Engineers
