以毛竹为原料,采用高压均质法、微滤沉积法、聚乙烯醇基体抛光法制备透明的纳米纤维素纸(透明纸).通过SEM、拉伸试验和UV-Vis测量系统分析了纳米纤维素纸的微观形貌与其力学性能和透光率的相应关系.研究结果表明多孔网状的纳米纤维素纸(纳米纸)以及抛光处理后的透明纸与传统的A4复印纸相比有着高的拉伸强度,并且网络伸展使其断裂伸长率也有所提高.透明纸的杨氏模量和拉伸强度分别为(1.31±0.35) GPa和(120.3±2.1) MPa.同时,采用聚乙烯醇高透明性基体抛光处理对纳米纸的透光性有着明显的改善,透明纸在600 nm处的透光率为65％.这种高强度透明纳米纸在柔性光电材料领域有着一定的应用潜力.
