Abstract

Mechanisms for the production of oriented precipitates are reviewed in the context of the orientation in mineralized biological tissues. Organic crystals have been oriented in polymer matrices by crystallization in a temperature gradient and by crystallization within a drawn crystalline polymer. Elongated oxide particles can be formed in a polymer by drawing of a material which contains phase-separated droplets of alkoxide, followed by hydrolysis of the alkoxide. Highly elongated rod-like or disc-like particles can be formed. Alternatively drawn films of a polymer blend can be swollen with alkoxide and hydrolysed to produce elongated chains of particles.
