Synthesis of Fabricated Polyurethane Matrix Based TiO2–HAp Material

Abstract

In this research work, the composition of polyurethane, titanium di oxide and hydroxyapatite were optimized to obtain a stable polymer nanocomposite microfilm with excellent flexibility and durability, through simple sol-gel synthetic method. The obtained films were further cut by nesting and formed to obtain a flawless stent structure with desirable mechanical, biocompatibility and drug delivery properties. XRD, FTIR, SEM characterizations were performed to study their physical, chemical and biocompatible properties. The tensometer tests, simulated body fluid tests and blood interaction tests showed competitive results that match the properties of conventional materials such as metals and alloys.
