Abstract: Synthesis and characterization of
chitosan-based composite, silica
and calcium phosphate
have been conducted. The purpose of this research was to study of the
effect of pH and chitosan on the composite character. Synthesis of materials
have carried out by sol-gel method. The optimum pH for this process was pH = 5.
Composite was synthesized using a variation of chitosan: (0.15, 0.25, and 0.35
g in 34 mL mixture). From optical microscope photoghraphs can be seen the
uniformity of the composite
particle obtained from
this research decrease
as the chitosan
content increase. FTIR show at
the availability functional group -OH and -NH of chitosan, phosphate, and Si-OH
and Si-O-Si of silica. The PSA analysis showed that there was no effect of the
amount of chitosan on to the change of particle size.
