Novel polystyrenes and their derivatives as biomaterials for human contact

Introduction

The above technology is based on polystyrene (PS) and their derivatives were well designed. They were synthesised by polymerization of specially prepared styrene monomers to be a desirable material as biomaterials for human contact. The polymers were fully characterized. Cell culture results indicate that our novel polymers containing the special group are non-toxic. They also mimic cell requirements and encourage human cell growth, eg. human osteoblasts, fibroblasts and red blood cells. Also they exhibit thermotropic smectic A (Sa) liquid crystallinity. Moreover, the polymers can form high quality ultrathin films onto substrates e.g. metallic or glassy substrate for some specific applications. To get well organized multilayer structure Langmuir-Blodgett film technique can be applied.

Area of Application

Medicine and pharmaceuticals

Advantages

The materials are non-toxic and biocompatible to human tissue. Sterilisation methods such as gamma irradiation are able to be applied without any effect to the material properties.
