ABSTRACT = {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 h. Cellulose 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 route. Homogeneous cellulosic regenerates
with high degree of polymerization and thermal stability characteristics were
obtained through a coagulation process in water. Furthermore, 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 reported. This 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.},
