[求助] 碳纳米管接枝聚乳酸

文献Single-Walled Carbon Nanotubes and Multiwalled Carbon Nanotubes Functionalized with Poly(L-lactic acid): a Comparative Study中在讲酰氯化的CNTs与PLA接枝的反应时,这样做:将溶有PLA的二氯甲烷溶液与碳纳米管混合后,加入三乙胺,然后氮气保护下70℃反应48h。二氯甲烷沸点40℃,70℃是为了什么呢,反应是在烧瓶壁上进行吗?还是我理解错了?原文:After cooling to room temperature, the excess SOCl2 was evaporated in a rotavapor to afford crude CNT-COCl (100 mg), which was resuspended in a solution of PLLA (500 mg) in CH2Cl2 (15 mL). Upon complete solution of the polymer, Et3N (1 mL) was carefully dropped over the mixture (exothermic reaction) and the dispersion was stirred for 48 h at 70 °C under nitrogen atmosphere.
