Morphological and Mechanical Properties of Poly (Vinyl Alcohol) Doped with Inorganic Fillers

Abstract

A number of polymer composite films using polyvinyl alcohol (PVA) as the preorganized polymer matrix were synthesized embedding different metal salts of transition elements like copper, cobalt, nickel, iron, cadmium, and zinc by a biomimetic route. The metal salts present in composites were reduced in situ to metallic form. The composites were characterized by FTIR, SEM, and EDAX. The SEM analysis confirmed the presence of nano-sized metal particles uniformly distributed in the polymer matrix. Mechanical properties were measured for various composite and PVA films. Significant improvement in some of the mechanical properties of polymer composites was realized in comparison with PVA.

Study of the nanostructure of free volume and ionic conductivity of polyvinyl alcohol doped with NaI

“…12 These fillers are broadly utilized in the plastics industry to cheaply accomplish the same levels of performance that might otherwise need much more costly engineering plastics; they facilitate surface bonding as a result of the surface of the filler which may be simply wetted by a polymer. 13 Polymer composites, the wonder materials are becoming the essential materials due to numerous technological applications such as electromagnetic and radio frequency interference shielding for electronic devices, photothermal optical recording, and direction-finding antennas. 14 Polymers such as polyvinyl alcohol (PVA), polyethylene glycol, polyvinyl acetate, polyvinyl chloride, polypropylene glycol, polyethylene oxide, and polyethylene terephthalate are convenient to prepare polymer composites with fillers.…”

A Study of FTIR and some Mechanical Properties of Sodium Iodide (NaI) Salt Filled Polymer Polyvinyl Alcohol (PVA) Films

“…Recently, several types of inorganic metal salts were used as fillers into (PVA) films and a strong effect of these metal salts on the mechanical properties of (PVA) was observed [4]. A significant improvement in mechanical, thermal, optical, electrical, and other properties of polymers can be achieved by adding different inorganic fillers [5]. The fillers are widely used in the plastics industry to cheaply achieve the same levels of performance that would otherwise require much more expensive engineering plastics; also they facilitate surface bonding because the surface of the filler can be easily wetted by a polymer [6].…”

Use of Ultrasound to Prepare Permeable Crosslinked PVA Membranes

“…PVA is a non-toxic, chemically stable, biocompatible polyhydroxy polymer and it has good film forming ability and high hydrophilicity [1,2]. Although PVA membranes have been commonly preferred for their high affinity toward water, especially in dehydration and separation processes [3][4][5][6][7][8], they have poor physical stability in water.…”

“…However, crosslinking process reduces the hydrophilicity of PVA membranes as well as their permeability. Although several alternative modifications have been used to address the reduced hydrophilicity and permeability of c-PVA membranes, e.g., grafting [2,5,13,14], blending [5,8,14] and filling with fine inorganic particles [1,[15][16][17][18][19][20][21], the use of efficient, eco-friendly green methods for the preparation of c-PVA membranes to minimize or eliminate undesired chemicals [22][23][24][25][26][27] is important, since in the last decade, increasing environmental awaerness needs to use eco-friendly methods.…”
