Improving the Tensile Properties of Curcuma Mangga Val Extract (CMVE)/PVA Nanofiber Mats by Using a Type of Non-Commercial CMVE

Abstract:

The commercially available Curcuma mangga Val extract (CMVE) and poly (vinyl alcohol) (PVA) blends were studied by electrospinning. The result showed inadequate tensile properties of commercial CMVE/PVA nanofiber mats with very high modulus (220.0 MPa) and low strain (50%). The commercial CMVE was then replaced by a type of non-commercial CMVE to compare them with those of the commercial bandage. A non-commercial CMVE was prepared by simply extracting of the fresh Curcuma mangga Val (CMV) produced in a liquid extract. This non-commercial CMVE was then blended with 10% (w/w) PVA at various concentrations of CMVE (0, 2, 5, 10 and 15%) (w/w). The morphology and tensile properties of the mats were investigated. The findings indicated that the tensile strength and modulus increased with CMVE concentrations, decreased of the mean fiber diameter. In this study, a nanofiber mat with a concentration of 2% CMVE was selected and compared to others. This mat had lower average fiber diameter (187.50 nm), tensile strength (8.93 ± 0.36 MPa) and modulus (31.37 ± 4.91MPa), and higher tensile strain (90%) than the commercial CMVE/PVA. Compared to the tensile properties of the Hansaplast bandage, the current tensile strength was higher, the tensile modulus was equivalent and lower tensile strain.
