本研究工作的目的是制备和表征环氧化天然橡胶-g-壳聚糖(ENR-g-CTS)/聚乙烯醇(PVA)复合材料纳米纤维。用静电纺丝技术制备了ENR-g-CTS/PVA复合材料纳米纤维,并用SEM、TEM和AFM方法观察ENR-g-CTS/PVA复合材料纳米纤维的微观形态。PVA纳米纤维和ENR-g-CTS/PVA复合材料纳米纤维的平均直径分别为约250和144 nm。与纯环氧化天然胶(ENR)相比,ENR-g-CTS在自然环境条件下的分解效果更好。此外,透过由ENR-g-CTS/PVA复合材料制备的载体膜,CSC释放20小时后的最大累积释放量达到18%。
The purpose of this work is to prepare and characterize the epoxidized natural rubber-g-chitosan (ENR-g-CTS) / polyvinyl alcohol (PVA) composite nanofibers. The ENR-g-CTS / PVA composite nanofibers were prepared by electrospinning technique. The morphology of the nanofibers of ENR-g-CTS / PVA composites was observed by SEM, TEM and AFM. The average diameters of PVA nanofibers and ENR-g-CTS / PVA nanofibers were about 250 nm and 144 nm, respectively. Compared with pure epoxidized natural rubber (ENR), ENR-g-CTS decomposes better under natural conditions. In addition, the maximum cumulative release after 20 hours of CSC release reached 18% through the carrier membrane prepared from the ENR-g-CTS / PVA composite.
