| 中文摘要: |
| 以醋酸纤维素（CA）和聚乳酸（PLA）为原料，采用流涎制膜法制备得到不同质量比的CA/PLA纳米纤维薄膜，并测试其在模拟海水中的可生物降解性。通过扫描电子显微镜、傅里叶变换红外光谱、热重分析等技术手段，研究了CA与PLA质量比对CA/PLA纳米纤维薄膜的理化结构及热稳定性的影响，并通过15天模拟海水降解实验，研究了CA/PLA纳米纤维薄膜在模拟海水中的降解性。结果表明，15天后CA/PLA纳米纤维薄膜的降解率优于单一CA薄膜，其中，CA与PLA质量比8∶2的CA/PLA纳米纤维薄膜降解率高达86.80%。 |
| Abstract: |
| Cellulose acetate （CA） and polylactic acid （PLA） were used as raw materials to prepare CA/PLA nanofiber films with different proportions by salivary membrane method， and the biodegradability was tested in simulated seawater. The effect of mass ratio of CA and PLA on physicochemical structure and thermal properties of the CA/PLA nanofiber films were studied by scanning electron microscopy， Fourier transform infrared spectroscopy， thermogravimetric analysis and other techniques. In addition， the degradability of CA/PLA nanofiber films in simulated seawater was conducted by a 15-day simulated seawater degradation experiment. The results showed that the degradation rate of the CA/PLA nanofiber films was better than that of a pure CA film， and the degradation rate of the CA/PLA nanofiber film with a mass ratio of 8：2 of CA and PLA was up to 86.80%. |
