摘　　要：玉米秸秆是我国主要农作物之一,合理利用秸秆资源对我们的生产生活具有重要意义。本文将玉米秸秆纤维素用戊二酸酐进行酯化,探究最佳酯化条件,利用月桂酸单甘油酯的特性,利用酸碱混合溶液水浴加热法提取纤维素,在不同工艺条件下与戊二酸酐进行酯化(反应温度,时间等),与月桂酸单甘油酯共混后制备抗菌性的纤维素膜。测定其热稳定性及抗菌性。改良纤维素膜的性能。Corn stalks are one of the main crops in China,and the rational use of straw resources is of great significance to our production and life.In this paper,corn stover cellulose is esterified with glutaric anhydride,explore the best esterification conditions,using the characteristics of lauric acid monoglyceride composite preparation of antibacterial cellulose film.Under different process conditions,esterify with glutaric anhydride(reaction temperature,time,etc.),blend with lauric acid monoglyceride to prepare antibacterial cellulose membrane.Determine its thermal stability and antibacterial properties.Improve the performance of cellulose membranes.
