碳纤维表面处理对脉冲电磁场作用下碳纤维增强聚乳酸基复合材料降解行为的影响
|
Abstract:
采用HNO3氧化对碳纤维进行表面处理，并制备了碳纤维增强聚乳酸基（CF/PLA）复合材料。研究了脉冲电磁场（PEF）对该条件下CF/PLA复合材料降解特性的影响。结果表明，碳纤维的表面处理对PEF作用下CF/PLA复合材料的吸水率、质量保持率、弯曲强度和剪切强度等均有不同程度的影响。分析表明，碳纤维表面处理形成的酯键在受到PEF作用后存在某种改变，进而导致CF/PLA复合材料界面降解行为的特异性。本研究有望提供一种从材料本身和外部条件协同控制的可降解CF/PLA骨折内固定装置解决方案。 The carbon fiber reinforced polylactic acid (CF/PLA) composites were specially prepared, with carbon fiber treated by nitric acid oxidation. The effect of pulsed electromagnetic fields (PEF) on the CF/PLA composite degradation characteristics under that treating condition was explored. The results show that, carbon fiber surface treatment has influences on the water absorption of CF/PLA composites mass retention, bending strength and shearing strength varying degrees under the PEF action. The analysis combined with the previous studies shows that the ester bonding formed by the carbon fiber surface treatment has existence of a sort of change under the role of PEF, which leads to specificity of the interface degradation of CF/PLA. The study is expected to provide a solution of synergistic control from the material itself and the external conditions degradable to improve CF/PLA internal fracture fixation device. 国家自然科学基金（51354001）；辽宁省教育厅重点实验室基础研究项目（LZ2014031）
