Poly(vinyl alcohol)-heparin hydrogels with varying water content were synthesized for use as sensor catheter membranes. Films were cast from aqueous mixtures of poly(vinyl alcohol) (PVA), a photosensitive cross-linker p-diazonium diphenyl amine polymer (PA), glutaraldehyde (GA) and heparin. After drying, the films were cross-linked by successive UV irradiation and heat treatment. To get an indi...

Although poly-vinyl alcohol (PVA) has certain mechanical drawbacks such as a weak barrier, it widely been used in food packaging over the last many years. To increase suitability of PVA (C2H4O)n and render ideal for packaging, diversity studies have already carried out. In below-mentioned script, we, first time, report use natural product osthol making new composite with enhancing thermal, phys...

Humidity-sensitive polymer, namely poly(vinyl alcohol-co-vinyl acetal), was deposited on a flexible poly(ethylene terephthalate) (PET) substrate pre-covered with sputtered Au:Pd thin layer in order to develop an optical humidity sensor. The spin-coating method applied for the polymer film deposition. and sensing properties of device were studied after repeated bending deformation range 25−1000 ...

To develop silk sericin (SS) as a potential antibacterial biomaterial, a novel composite of polyelectrolyte multilayers (PEMs) coated sericin/poly(vinyl alcohol) (SS/PVA) film modified with silver nanoparticles (AgNPs) has been developed using a layer-by-layer assembly technique and ultraviolet-assisted AgNPs synthesis method. Ag ions were enriched by PEMs via the electrostatic attraction betwe...
