Polymer Infiltration Toughened Hydroxyapatite Biomaterial Hybrids by Bio-inspired Materials Design

摘要

Conclusions: Our preliminary investigation showed a significant increase in scratch toughness of HA template after infiltration reach to an important conclusion that polymer infiltration into nano-porous network provides higher resistance to scratch which seems to be due to designed thin organic interfaces and possibly as a result of sliding between PVA and HA particles Further studies of efficacy of toughening in these hybrid systems and optimization of porosity of HA templates and polymer infiltration are underway to fabricate tough polymer-HA hybrids by closely mimicking bio-inspired natural materials. . These results are significant in our opinion, since formulation of this approach to fabricate thin compliant polymer interfaces by nano-porous HA fabrication, followed by polymer infiltration can be potentially used in the fabrication of orthopedic biomaterials with enhanced mechanical performance.
