Abstract
Abstract Optically transparent and cable-like Polyacrylonitrile/polyacrylic acid (PAN/PAA) nanofibres filled with ultrafine fibrils were obtained via eletrospinning at a high relative humidity. PAN fibrils 20.8 nm in diameter were dispersed in the nanofibre core. The optical property of composite NFs membrane can be tailored by atmosphere humidity during electrospinning and the bicomponent proportion. The transmittance and the tensile strength of these composites increased with the content of PAA increasing, their transmittances were from 74.8 to 88.8% and tensile strengths were from 12.0 to 15.6 MPa, much higher than pristine PAN NFs of 46.0% and 5.7 MPa. Optically transparent PAN/PAA composites have potential to be a promising alternative as components of optoelectronic devices.
