Amino cellulose (AC) is a cellulose derivative with biodegradability, biocompatibility, and excellent film-forming property, but AC film exhibits poor mechanical property and thermal stability. To improve the performance of AC film and further promote application, a novel composite film prepared from AC and bisphenol A-type-benzoxazine (BATB) are reported. In this paper, AC and BATB were firstly synthesized and characterized, then AC-BATB composite films were prepared with different weight ratios (AC/BATB) and temperatures by the synergistic interactions of chemical cross-linking and hydrogen bonds. Based on the results of tensile test and thermal analysis, BATB played a vital role in improving the mechanical and thermal properties of composite films, and the enhancement effect was more remarkable at elevated temperature. The maximum tensile strength and tensile modulus of composite films were 2.86 times and 7.26 times higher than that of AC control film, thus promoting the functional application of composite films.
氨基纤维素（AC）是一种具有生物可降解性、生物相容性和优异成膜性能的纤维素衍生物，但AC膜的机械性能和热稳定性较差。为了提高AC膜的性能并进一步促进其应用，本文报道了一种由AC和双酚A型苯并恶嗪（BATB）制备的新型复合膜。本文首先合成并表征了AC和BATB，然后通过化学交联和氢键的协同作用，在不同的重量比（AC/BATB）和温度下制备了AC-BATB复合膜。基于拉伸试验和热分析结果，BATB在改善复合膜的机械和热性能方面发挥了重要作用，并且在高温下增强效果更为显著。复合膜的最大拉伸强度和拉伸模量分别比AC对照膜高2.86倍和7.26倍，从而促进了复合膜的功能应用。
