将稻草经清洗、蒸汽爆破、粉碎等工艺处理后，在100℃条件下用离子液溶解稻草粉末，得到秸秆溶液，采用延流法制得了平面膜，并选用医用纱布和细平布做增强基材，将制得的秸秆溶液与细平布及医用纱布复合，冷却洗净，去除离子液后晾干，得到高气密性增强膜。并分析了平面膜的化学成分，结果表明其保留了原稻草秸秆的主要化学成分，且含量相差不大。还对增强膜与平面膜进行了表面形态、回潮率、透湿性能、透气性能、力学性能研究对比，研究结果表明，秸秆液在医用纱布和细平布表面形成无界面致密膜，这种增强膜具有高气密性、强吸湿性、较好的力学性能。

This paper provided a method of using straw to prepare high airtightness antimicrobial enhanced membrane, after cleaning, blasting and griding, dissolve the straw sample at 100°C in the ionic liquid [bmim]Cl, combine the straw solution with  the medical gauze and cotton plain weave fabric, high airtightness antibacterial enhanced membrane can be obtained after washing and drying.Chemical composition of original membrane which hasn't composited with fiber has compared with straw's.The surface morphology, moisture regain, water vapor permeability, air permeability and mechanical properties of the enhanced membrane were studied and compared with the original membrane . The results showed basic chemical composition of the straw has been saved in the original membrane ; the straw liquid completely composites fabric surface to form a layer interface dense film; the tidied reinforced membrane has high air tightness, strong moisture absorption and good mechanical properties.
