Intramolecular crosslinking of poly(vinyl alcohol)
Poly(vinyl alcohol) is crosslinked in dilute solution (c = 0.1 wt%) with glutaraldehyde. The reaction product is characterized by viscometry and gel permeation chromatography (g.p.c.). The intrinsic viscosity decreases with increasing degree of crosslinking and does not depend on temperature. G.p.c. reveals that the reaction product is not homogeneous, but consists of a mixture of particles wit...
متن کاملRole of Nano-Sized TiO2 on Mechanical and Thermal Behavior of Starch/Poly (vinyl alcohol) Blend Films
A novel Starch/Poly (vinyl alcohol)/nano-Titanium dioxide (ST/PVA/nano-TiO2) biodegradable nanocomposite film was prepared by homogeneously dispersed TiO2 nanoparticles in different ratios of starch/PVA-based materials, via a solution casting method. Glycerol was used as plasticizer. The mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...
متن کاملMagnetic investigation of microwave synthesized and thermal stable poly vinyl alcohol-cobalt ferrite nanocomposites
We synthesized CoFe2O4 nanoparticles using heating in various times by simple microwave method at power about 600W. Water, ethylene glycol and their combination were used as solvent. X-ray diffraction pattern(XRD) analysis was performed for evaluation of structural characterization of samples. We also used scanning electron microscopy (SEM) to evaluate the effects of various parameters of heati...
متن کاملThe Plasticizing Mechanism and Effect of Aluminium Chloride and Glycerin on Poly(vinyl alcohol) Films
Poly(Vinyl Alcohol) (PVA) films were prepared with AlCl3·6H2O/glycerin and AlCl3·6H2O/poly glycerin as two kinds of complex plasticizer. The micromorphology of pure PVA film and PVA films plasticized with complex plasticizer was observed by Scanning Electron Microscope (SEM). The interaction between complex plas...
متن کاملSynthesis and characterization of α-Alumina membrane supports and the binding effect of Poly (Vinyl Alcohol)
Ceramic Ultrafiltration membranes are considered as an alternative for the treatment of both stable water-in-oil and oil-in-water emulsions proved to be more effective in comparison with other conventional techniques. In this study, symmetric macro-porous ceramic membranes are prepared through dry pressing of α-alumina powder and the addition of various binders including Poly (vinyl alcohol). T...
