Abstract:
For the purpose of developing of disc nucleus replacement (semicrystalline PVA hydrogel elastomers) and explorating the possibility of clinical application, in this study,the aqueous PVA solution froze at -20 degrees C for 6-12 h, and then thawed at room temperature for 1-2 h. The same process was repeated 1-3 times. After the specimen was dehydrated in vacuum, a kind of artificial disc nucleus materials (semicrystalline PVA hydrogel elastomers ) was formed. DSC and mechanical tests were conducted to investigate the influence of aqueous PVA solution concentration, of dehydrating in vacuum, and of gamma-ray irradiating upon the degree of crystallity and mechanical properties of PVA hydrogel elastomers.
