不同质量比N,O-CMC/n-β-TCP复合材料在模拟体液中的降解性能

Abstract

Abstract:

To evaluate the degradation property of the N,O-CMC/n-β-TCP composites with different mass proportion in simulated body fluid in vitro. The changes of pH, calcium concentration, phosphonium concentration,the weight, surface structure, components of the composites were detected at different time. The pH of SBF is over 6.9 in all composites, especially when the proportion is 1:1(pH:7.0-7.4). The weight increases with the degradation time.The bone-like apatite formed on the surface of all the composites and the largest number of bone-like apatite formed when the proportion is 1:1.

Key words: materials experiment, nano-β-tricalcium phosphate, N,O-carboxymethyl chitosan, simulated body fluid, X-ray diffraction, Fouriery transform infraded
