Evaluating the Volume Ratio Effect on Absorption Time of Polyvinyl Alcohol-Sodium Alginate Based Fiber Membranes as a Wound Dressing

Abstract

This research was observed absorption of the membrane PVA/SA fiber as wound dressing. The electrospinning method is used to make fiber membranes. This method with a volume ratio composition of Polyvinyl Alcohol (PVA) - sodium alginate (SA) (PVA/ SA) of 9 :1 (v/v), 8:2 (v/v), and 7:3 (v/v). The PVA/SA membrane was characterized with absorption characterization-water absorption test, morphology and fiber diameter. Absorption characterization-water absorption test results that the fastest absorption time occurred on the PVA/SA fiber membrane with a ratio of 7:3 (v/v). From the SEM results, it is known that the morphology of the PVA/SA membrane shows a fiber size with a uniform diameter. The fiber diameter decreases as it increases SA volume fraction. Fibers with a small diameter will have a large surface area and absorb liquid more quickly. Keywords: electrospinning, wound dressing, absorption characterization-water absorption test, size fiber
