纳米纤维素增强CMC/SiO2复合膜的性能研究

近年来膜技术不断在各个领域渗透，并且应用越来越广，成分单一的膜已经不能满足各领域的需求，尤其在航空航天、军事和国防等特殊领域，对所应用的膜的性能标准更高，通过将两种以上成分复合，使膜功能互补和优化，制备出性能优异的复合膜是当今时代发展的必然趋势。本工作研究将羧甲基纤维素（CMC）与SiO2纳米颗粒和纳米纤维素(CNF)混合，制备出具有较好的耐热性和机械强度的纳米复合薄膜。该复合膜可以在物质分离、生物传感器等方面被深入研究并加以应用。

Study on Properties of Nano Cellulose Reinforced CMC / SiO2 Composite Membrane

In recent years, membrane technology has continuously penetrated into various fields and is more and more widely used. The membrane with single component can no longer meet the needs of various fields, especially in special fields such as aerospace, military and national defense. The performance standard of the applied membrane is higher. By compounding more than two components, the membrane functions are complementary and optimized, It is an inevitable trend to prepare composite membranes with excellent properties. In this work, carboxymethyl cellulose (CMC) was mixed with SiO2 nanoparticles and nano cellulose (CNF) to prepare nanocomposite films with good heat resistance and mechanical strength. The composite membrane can be deeply studied and applied in material separation, biosensor and so on.
