纸基材料亲水性转变途径

Paper-based Material Hydrophilicity Transition

纸张是以纤维为主要原料制成的多孔性材料,该原料易得,具有一定的轻质、柔韧、机械性能强度高和绝缘等优质特性,但其亲水性很强,亲水后纸的强度等性能下降显著,因此其亲水性限制了其广泛应用。随着现代科技的发展,纸张除了作为书写、印刷、包装等材料使用以外,作为功能材料的需要越来越高。很多用途要求纸张具有一定的疏水性,如食品包装等系列纸产品均要求纸张具有一定的疏水性能和机械强度。因此为扩大纸张作为功能材料的使用范围,纸张由亲水性向疏水性的转变显得十分重要和有意义,现在纸基材料的疏水性也成为研究热点,本文概述了纸的基本性能和结构,并介绍纸基材料疏水性转变途径。

Paper is a porous material which mainly made of fiber,the cellulose materials are not only readily available in nature,but also have the flexible,strengthful,insulation,hydrophilic,and other high-quality features.However,its higher hydrophilic property declined the strength performance significantly,which limited the paper widespread application.With the development of modern science and technology,paper even could as a functional material in addition to writing,printing,packaging,and other materials,such as food packaging and other series of paper products are required paper has some hydrophobic properties and mechanical strength.Therefore,in order to expand the use of paper as a functional material,the transformation of paper from hydrophilic to hydrophobic appears to be very important and meaningful.Today the hydrophobicity of paper-based materials has also become a reaserching hotspot.This paper outlines the basic properties and structures of paper,and then introduced the hydrophilicity transfer path of paper-based materials.
