Formation thin film nanofibre of polyacrylic acid (PAA) -carboxymethylcellulose (CMC)-polyethylene oxide (PEO) using electrospinning technique: article

Formation of thin film nanofibre of PEO-CMC-PAA was conducted via electrospinning technique. Three different solutions were prepared namely PAA-ethanol, PEO-water-ethanol and CMC-water before vigorously mixed together forming polymer blend solution. Viscosity and conductivity were measured before electrospinning. The electrospun nanofibre was characterized by using Field Emission Scanning Electron Microscope (FESEM), contact angle and Fourier Transform Infrared Spectroscopy (FTIR). The electrospun nanofibers of PAA-CMC-PEO was analyzed by using FESEM and average diameter of 400 nm was obtained by using Image J software. The contact angle measurement of electrospun nanofibers is 20.20⁰. Compounds of O-H, R-C=OO, RC=O, cellulose, CH3 and C-O-H were obtained in polymers solution and electrospun nanofibers via Fourier Transform Infrared Spectroscopy. This study contributes a promising approach to fabricate an electrospun nanofiber from the blended polymer of PEO-CMC-PAA.
