Abstract

A new method combining frontal ultrafiltration and ultrasound, followed by UV photocrosslinking enabled the fabrication of orthotropic CNC/PEGDA (poly(ethylene glycol) diacrylate) nanocomposites with the structure of articular cartilage. In situ SAXS compression/relaxation mechanical tests demonstrated this orthotropic organization as well as elastic behavior with a Young's modulus of 0.76 MPa, similar to articular cartilage.

模拟关节软骨结构的纤维素基纳米复合材料在单轴压缩下的结构机制

采用正面超滤和超声结合的新方法制备了具有关节软骨结构的正交各向异性CNC/聚乙二醇双丙烯酸酯纳米复合材料。原位SAXS压缩/松弛力学试验证明了这种正交各向异性组织和弹性行为，杨氏模量为0.76 MPa，类似于关节软骨。
