摘 要：Introduction of the strategy of anhydrous calcium carbonate protection incorporated with the drop by drop reaction,high-purity 1-butyl-3-methylimidazolium chloride([Bmim]Cl)was prepared at reaction temperature of 80°C for only 10 *** samples from different biomass sources(with different degree of polymerization characteristic)could be rapidly(no more than 10 minutes)and completely dissolved in the[Bmim]Cl using a microwave-assisted ionothermal *** cellulosic regenerates with high degree of polymerization and thermal stability characteristics were obtained through a coagulation process in ***,the dissolved celluloses were readily regenerated into solid products such as casting films and spinning fibers,which exhibited high transparency and flexibility,as well as superior mechanical properties of over 300 MPa(tensile strength)more than those of cellulose samples *** study therefore provides a new process for the synthesis of high-purity[Bmim]Cl for the highly efficient dissolution of cellulose to produce high performance cellulosic materials for various applications such as flexible electronic,optoelectronic,soft robots.
