Advanced functional materials based on cellulose

Abstract: As the most abundant natural polymer on the earth,cellulose has many attractive properties such as renewability,biodegradability,biocompatibility,and broad chemical-modifying capacity.Therefore,cellulose has been considered as the sustainable raw material of energy and chemical engineering in the future.Nowadays,cellulose has attracted a worldwide attention as a renewable resource that can be converted into high value products,in which specific attention has been paid on cellulosebased advanced functional materials.Based on about 360 relevant papers published during the past 5 years,this review highlights recent progress in cellulose-based advanced functional materials from the view of fabrication methodologies.The various cellulose-based functional materials,such as fiber materials,membrane materials,photoelectric materials,hybrid materials,smart materials,and biomedical materials,are described,along with their preparation,properties and applications.Finally,a perspective on this promising family of materials and the research that needs to be done in the future are briefly discussed.It is hoped that this review work will stimulate research and collaborations that will lead to significant progress in this area.

Synthesis of 1-allyl,3-methylimidazolium-based room- temperature ionic liquid and preliminary study of its dissolving cellulose

Abstract: A novel room-temperature ionic liquid (RTIL),1-allyl,3-methylimidazolium chloride (［AMIM］Cl),was synthesized,ch aracterized and used for dissolving cellulose.The solubility of cellulose in ［ AMIM］Cl was better than in 1-butyl,3-methylimidazolium (［BMIM］Cl).The pris tine cellulose and two cellulose samples regenerated from ［AMIM］Cl and ［BMIM ］Cl solutions were compared by FTIR,WAXD and TGA measurements.Results show t hat these two RTILs are non-derivatizing solvents for cellulose.After regenera tion from RTIL solutions,the crystalline form of cellulose films is completely transformed from cellulose Ⅰ to cellulose Ⅱ.Compared to pristine cellulose,t he regenerated cellulose exhibits a lower onset temperature of thermal decomposi tion,with a higher char yield.

α,ω -3-二(3-氨基丙基)-聚三氟丙基甲基硅氧烷及其改性聚氨酯脲的合成与表征及体外氧化稳定性研究

Abstract: 通过一步反应,直接合成了α,ω-3-二（3-氨基丙基）-聚三氟丙基甲基硅氧烷,并进行了表征,然后将其与聚四氢呋喃二醇（PTMG）作为混合软段,合成了不同FPS含量改性的聚醚型聚氨酯脲（FSPUU）.研究了FSPUU膜的表面性能和形态结构,实验结果显示FSPUU膜的表面呈现憎水性,与F元素富集于表面有关.将FSPUU膜浸没于CoCl2-20%H2O2溶液中进行了为期21天的加速氧化处理,并估算了PTMG软段的降解程度.与PDMS改性PUU（MSPUU）相比,FSPUU的氧化稳定性增强,与FSPUU在水和H2O2溶液中较低的溶胀率以及透水率有关.此外,FSPUU膜显示出较好的力学性能,其拉伸强度和断裂伸长率均高于MSPUU.
