| 摘要:本研究比较了4种商用二醋酸纤维素（CDA）在丙酮体系中的溶解性能，并对其形貌、化学组成、结构及热稳定性进行了系统表征。结果表明，不同CDA在溶解性和溶液均一性方面存在明显差异，其化学组成及结构的差异共同影响其在丙酮中的溶解行为。4种CDA的取代度在2.42~2.55，其中取代度相对较高的CDA表现出较高的热分解温度和熔融转变温度，而取代度相对较低的CDA则表现出较好的溶解性和成膜均一性。 |
| Abstract:In this study, the dissolution performance of four kinds of commercial cellulose diacetate (CDA) in an acetone system was compared, and their morphology, chemical composition, structure, and thermal stability were systematically characterized. Significant differences were observed in the solubility and solution uniformity of the different CDA, and the differences in composition and structure were found to jointly influence their dissolution behavior in acetone. The degrees of substitution of the four kinds of CDA were determined to be in the range of 2.42~2.55. The CDA with relatively higher degrees of substitution were found to exhibit higher thermal decomposition temperatures and melting transition temperatures, whereas better solubility and film-forming uniformity were obtained for the samples with relatively lower degrees of substitution. |
