Applications of self - assembling systems for the growth of nano crystalline ceramics (abstract)

Present work is carried out to synthesize nano hydroxyapatite ceramic particles using the self assembling properties of surfactants. To implement the self assembling behavior as templates, different surfactants are selected on the basis of different charged head groups and chain lengths to compare the morphological aspects of the synthesized nano particles. The factors which affecting the morphology of the particles i.e. the packing parameters of the amphiphilic surfactant molecules are investigated theoretically and by some means co-relate with the experimental values. It is observe that pH, temperature, stirring rate, surfactant concentration and the counter ions affect the morphology of the particles. The precipitation route is used to produce the nano particles and is characterized for molecular composition, phase analysis and morphology by FTIR, XRD and SEM respectively. (author)
