对四乙基氯化铵(TEAC)/二甲亚砜(DMSO)/乳酸体系中溶解的纤维素的再生方式进行研究。考察了再生方式对再生纤维素得率的影响,并采用SEM(Scanning Electron Microscope)、FTIR(Fourier Transform Infrared Spec-troscopy)、XRD(X-Ray Diffraction)、DP(Polymerization Degree)、TG(Thermogravimetry)、DSC(Differential Scanning Calorimetry)对再生纤维素进行了表征。
The regeneration of dissolved cellulose in tetraethylammonium chloride (TEAC) / dimethyl sulfoxide (DMSO) / lactic acid system was studied. The effect of regeneration mode on the yield of regenerated cellulose was investigated. The scanning electron microscopy (SEM), FTIR (Fourier Transform Infrared Spec-troscopy), X-ray diffraction (XRD), DP (Polymerization Degree) and TG (Thermogravimetry) , Regenerated cellulose was characterized by DSC (Differential Scanning Calorimetry).
