In DSC measurements, the second heating run was used to eliminate the effect of solvents and heat history on glass transition temperature ( Tg), and also physical aging was used to improve the sensitivity of Tg measurements by enhancing the enthalpy endothermal peaks.

  • DSC法中采用二次扫描以消除溶剂和热历史的影响,并利用物理老化方法来增强N-烷基壳聚糖在DSC曲线上的玻璃化转变区域的热焓吸热峰,以克服DSC法的不灵敏性。
