Preparation and Properties of Double Network Hydrogels Based on Gellan Gum and Polyethylene Glycol Acrylate?
摘要
Abstract
Hydrogels have the similar 3D micro-environment as the native extracellular matrix and hold great potential in future biomedical applications. However the mechanical performance limited their applications. The double network hydrogel( DN gel) attracts much attention due to its high mechanical properties. This study aimed to prepare a series of DN gels based on gellan gum and polyethylene glycol acrylate ( PEGDA) to improve the toughness of gellan gum hydrogel for 3D cell culture and tissue repair. The DN hydrogels exhibited better mechanical properties, with the tensile fracture energy up to 1. 01 × 103 J/m2 , which was similar to the value of natural articular cartilage. Our study suggests that the DN gel based on gellan gum and PEGDA present promising mechanical performance and cell seeding efficiency. These hydrogels may have prospective applications in the fields of wound dressing, artificial cartilage and tissue engineering scaffold materials which require high mechanical properties.关键词
