چکیده
ABSTRACT. Biopolymers are referred to the bio-degradable polymer that is derived from living organisms in nature or synthesized renewable materials but needs polymerization. There consisting of monomeric units bond together through a covalent obtain large molecules. A biopolymeric blend sodium carboxymethyl cellulose/sodium alginate (Na-CMC/SA) film was prepared by casting/solvent evaporation method. In addition molecular structure, optical and geometry collected films were characterized. XRD binary investigated interaction miscibility among two biopolymers. FTIR spectrum explicated conferring group’s vibrations. UV/Vis studies appeared peak at wavelength (227 nm) which explained high combination between polymers. Molecular clarifies assignment vibrational spectra pure polymers implied important role (C=O) group as eventful regions for polymers.

PES/Quaternized-PES Blend Anion Exchange Membranes: Investigation of Polymer Compatibility and Properties of the Blend
Polyethersulfone (PES)-based anion exchange blend membranes were prepared from quaternized-PES (Q-PES) and N-Methyl-2-pyrrolidone (NMP) casting solutions with water as coagulant via non-solvent induced phase inversion. The compatibility of the blend system was investigated through thermodynamic studies while membrane formation was determined using the cloud point techni...

15 صفحه اولCharacterization of Natural and Synthetic Polymer Blend Scaffolds for Tissue Engineering
Introduction: Tissue engineering provides an approach for generating functionally replaceable tissue parts. Biodegradable scaffolds are used to support and guide the in-growth of cells. The idea is that the scaffolding material eventually disappears leaving only the necessary healthy tissue in a topologically required form (1,2). While numerous biodegradable polymers have been investigated as c...
متن کاملRelease of theophylline from polymer blend hydrogels.
Polymer blending is a simple yet attractive method to obtain combined physical and mechanical properties of polymers. In this paper, three types of blend hydrogels were prepared, each by physically blending two different natural polymers, and a model drug, theophylline (TPH), was immobilized into these hydrogels for the studies of drug release. The release profiles of TPH from various types of ...
