The tensile properties of electrospun Poly Vinyl Chloride and Cellulose Acetate (PVC/CA) bi-component polymers nanofibers
Abstract
Cellulose Acetate and Poly (Vinyl Chloride) nanofibers have found diverse usages in several different domains. The nanofiber mat has proven to be an efficient media for the ultra-filtration when applied on the surface of other woven or nonwoven filters media. However, this thin layer of nanofiber application needs to have enough strength that can withstand the applied forces. To improve its strength, it is suggested to blend two polymer types. In this study, Poly (Vinyl Chloride)/Cellulose Acetate blends nanofibers were successfully prepared using electrospinning. The morphology, physical, and mechanical properties of nanofibers mats were investigated. The analysis of Poly (Vinyl Chloride)/Cellulose Acetate nanofibers electrospun mats indicated substantial property improvement in electrospun fibers mats which was achieved by adding 8% Cellulose Acetate. It increased in Poly (Vinyl Chloride) nanofibers mat breaking strength by 350%, breaking extension by 210%, first modulus by 164% and second modulus by 227%, and work of rupture by 753%.
