The porosity and morphology of PU foams prepared by solvent casting/salt leaching method with different solvents
Abstract
In this study, the polyurethane (PU) system based on poly(ethylene-butylene) adipate diol, 1,6-hexamethylene diisocyanate, 1,4-butanediol and ascorbic acid is used to prepare a foamed material. Polymer foams were created using solvent casting/salt-particle leaching (SC/PL) method. The influence of the PU concentration in different solutions [either in a DMF or in DMF with THF as a co-solvent] on the morphology and porosity of the foam was investigated. The PU foam prepared from a 10% solution in a DMF/THF mixture had the highest porosity value equal to 86% and the size of the pore was in a rage of 100–300 µm. Obtained foam meets the requirements of the scaffolds in terms of the porous structure.
