Abstract
Porous β-tricalcium phosphate/chitosan/polyvinyl alcohol (β-TCP/CS/PVA) composite hydrogel was prepared successfully by the freezing-thawing method using NaCl as porogen. The effects of different mass ratio of CS to β-TCP on the crystallinity of PVA and the performance of target β-TCP/CS/PVA composite hydrogel has been studied. The products were characterized by means of XRD, SEM, TG-DTA and their water uptake, swelling ratio, and tensile strength were also determined and compared. The water uptake of the hydrogel composite was about 70% ~76% (mass fraction). When the mass ratio of CS to β-TCP was 2:8, it exhibited good mechanical properties: tensile strength of 0. 56 Mpa and elongation at breakage of 370% which can withstand normal human eye pressure. Therefore, the porous β-TCP/CS/PVA hydrogel composite is promising to be used as the skirt for artificial cornea.关键词
