Improvement of material properties of PVA hydrogels for artificial cartilage

 The optimization of nanoscopic and microscopic structure and surface properties of PVA hydrogels is needed for high-performance artificial cartilage. The Improvement of strength, durability, super-lubricity and permeability based on the technology fusion of various processing methods should be established.
