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.
