Ambient temperature affect the pore size of PVA Nano fibers tissues

Abstract EN

Electrospinning has recently emerged as a leading technique for generating biomimetic scaffolds made of synthetic and natural polymers for tissue engineering applications.

PVA was dissolved in distilled water at concentration (10% wt).

PVA 10% DW solution was prepared as biopolymeric materials for fabricating tissue engineered scaffolds by electrospinning, varying ambient temperature (25, 30, 35, 40, 45 and 50) ͦ C and investigated the ambient temperature effect on tissue nanofibers pore size.

Scanning electron microscopy was utilized to profile the topography of individual electrospun fibers.

Statistical measurements for each SEM images lead to measure the mean pore size of tissue obtained.

Our results indicate that the average pore size of PVA fiber tisues could be scaled down to mean values (132-300)nm smooth nanofibers without any beads, pore size decreased as ambient temperature increase to certain temperature at (40 °C) and retrain increasing at (45 and 50) °C temperature
