Control of nanoparticle size of fillers by polymer blend technique

Nanosize particles of calcium phosphate were prepared by a new technique ba sed on matrix mediated control of growth and morphology using polymer. blen ds. The particle size could be reduced down to the order of 10 nm at a cert ain composition of the blend. These particles were stabilized and could be handled easily due to the polymer matrix surrounding them. Their crystal st ructure and size was confirmed by X-ray diffraction and electron microscopy .
