摘要: In order to form firm active fixation with the adjacent bone, a new kind of bioactive composite hydrogel was prepared polyvinyl alcohol (PVA) and bioglass (BG) through ultrasonic dispersion, heat-high-pressure freeze/thawed technique. A digital speckle correlation method (DSCM) utilized characterize mechanical properties series BG/PVA composites. Results showed that at different load pressures, displayed displacement deformation in V field. also an increase PVA percentage (15-30 wt%) or (2-10 could lead elastic compression modulus. Scanning electron microscope results indicated uniformly dispersed hydrogel. The shows promising prospect as bionic cartilage implantation material.
