Abstract
|
Highly porous bi-component fibers from poly (ethylene oxide) (PEO)/polyacrylonitrile (PAN) blends with 90/10, 80/20, 70/30, and 50/50 PEO/PAN weight ratios were prepared. Electrospinning of the blends produced thin fibers with averaged diameters ranging from 275 to 190 nm. Incorporation of 1 wt% graphene sheets (GS) into the fibrous blends mats effectively increased the tensile modulus and electrical conductivity of the matrix. Differential scanning calorimetry (DSC) showed the lowered Tm and ·Hm of the PEO component in the bi-component fibers, suggesting that the crystallization of PEO was hindered due to the presence of PAN. DSC results indicated a nucleation effect of GS on the crystallization of PEO. High porosity of the produced nanocomposite mats (about 93%) is a promising feature for their application as electrolytes. J. VINYL ADDIT. TECHNOL., 2016. © 2016 Society of Plastics Engineers
