Abstract

Carboxymethyl starch (CMS) is a natural polymer derived from sago starch that is obtained from sago palm (Metroxylon spp.). Herein, CMS was used as a polysaccharide source in preparations of composite nanofibers with poly(L-lactide acid) (PLLA). The incorporation of CMS with PLLA in nanofiber form has great potential to be used in biomedical applications. The composite PLLA/CMS nanofibers were fabricated by electrospinning technique at various ratios of CMS, which were 5, 10, 15, and 20% vol/vol. The composite nanofibers were characterized according to their physical morphology, chemical interaction, wettability, water uptake, and thermal and mechanical behaviors. The result showed that uniform and bead-free nanofibers were produced at the low ratio of CMS while fractal and discontinuing fiber was observed at a high ratio of CMS. A better mechanical strength was obtained at low CMS ratio as compared with higher one. Fourier transform infrared results showed that there was an interaction between CMS and PLLA after electrospinning. The surface hydrophilicity and water uptake increased with increasing ratio of CMS. The results from the differential scanning calorimeter analysis showed the decrease of the glass transition (Tg) and cold crystallization temperature (Tcc) of the nanofiber after addition of CMS in PLLA.
