Friction Properties of Poly (vinyl alcohol)/Hydroxylapatite Hydrogel Prepared by Compound in situ with Sol-gel Method
沉淀法制备PVA/HA复合水凝胶的摩擦性能研究

The poly(vinyl alcohol)/hydroxyapatite composite hydrogel was prepared by compound in situ with sol-gel method.The microstructure of HA in composite hydrogel was observed using an Optics Microscope.The elastic modulus of compression and stress relaxation character of PVA/HA composite hydrogel were measured with the flat cylindrical head.The contact deformation of PVA/HA composite hydrogel was measured with a high precision displacement sensor.The reciprocating sliding friction tests of PVA/HA composite hydr...
