Biocompatibility and biodegradability of filler encapsulated chloroacetated natural rubber/polyvinyl alcohol nanofiber for wound dressing. Mater Sci Eng C Mater Biol Appl. 2019 Oct;103:109829 Authors: Azarian MH, Boochathum P, Kongsema M Abstract The novel biodegradable films of chloroacetated natural rubber/polyvinyl alcohol (CNR/PVA) (55/45 wt%) non-woven nanofiber films encapsulated with kaolin and starch (2.5 and 5 wt%) were produced successfully by green electrospinning technique. The effect of fillers with different content on the physical, chemical, mechanical, biocompatibility and biodegradation properties of CNR/PVA nanofiber films were investigated. The higher crystallinity obtained in CNR/PVA encapsulate with 2.5 wt% kaolin and nanofibers were formed with the maximum diameter distribution and mean value of 40-160 nm and 94.15 ± 54.19 nm respectively. DSC and DMA revealed the kaolin can improve the interfacial adhesion between CNR and PVA and contribute to enhancing the chemical interactions. The mechanical properties improved upon encapsulation of starch and kaolin and more favourable nanofibers with smaller diameter obtained using kaolin rather than starch. The cytotoxicity results revealed the viability of the prepared nanofiber films with human dermal fibroblast cell. Furthermore, the incorporation of starch and kaolin accelerated the degradation rate and the highest enzymatic degradation obtained with 2....
