摘要
A new type of biocomposite of nano aptite (NAP)/poly(1,4-phenylene sulfide)-poly (2,4-phenylene sulfide acid) (PPS-PPSA) copolymer (NAP/PPS-PPSA) was prepared by polycondensation in 1-methyl-2-pyrrolidone (NMP). The NAP particles with a size of about 40-60 nm in diameter and 60-80 nm in length uniformly distributed in the composite. The presence of 2,4-phenylene sulfide acid in copolymer increased the copolymer affinity to NAP. Duo to some strong combinations of calcium ion (Ca2+), carboxyl (-COO-) and phosphate radicals ion (PO43-) in the composite, interfacial chemical binding exists between copolymer and NAP. The NAP/ PPS-PPSA biocomposite not only had good homogeneity but also had high NAP content of 60%, which was a potential bioactive material to be used as load-bearing implants or fixation in bone repair.
