The mucoadhesive hydrogel film was prepared and optimized for the purpose of local drug delivery to oral cavity for the treatment of oral Candidiasis. The mucoadhesive hydrogel film was prepared with the poly(vinyl alcohol) by freeze/thaw crosslinking technique. 3(2) full factorial design was employed to optimize the formulation. Number of freeze/thaw cycles (4, 6, and 8 cycles) and the concent...

A selectively cross-linking method, which is based on the ‘‘di–diol” interaction between poly(vinyl alcohol) and borate and the strong electrostatic interaction between chitosan and tripolyphosphate, was developed. Chitosan/poly(vinyl alcohol) films cross-linked separately with borate, tripolyphosphate and borate/tripolyphosphate were then prepared in terms of this method. Water vapor permeatio...

Quantitative insights into the stress-transfer mechanisms that determine the mechanical properties of tunicate cellulose whisker/poly(vinyl acetate) nanocomposites were gained by Raman spectroscopy. The extent of stress-transfer is influenced by local orientation (or anisotropy) of the whiskers, which in turn is governed by the processing conditions used to fabricate the nanocomposites. Solutio...

Nanocomposites of poly(3-hexylthiophene)-cadmium selenide (P3HT-CdSe) were synthesized by directly grafting vinyl-terminated P3HT onto [(4-bromophenyl)methyl]dioctylphosphine oxide (DOPO-Br)-functionalized CdSe quantum dot (QD) surfaces via a mild palladium-catalyzed Heck coupling, thereby dispensing with the need for ligand exchange chemistry. The resulting P3HT-CdSe nanocomposites possess a w...

Three distinct polymers were used as model in this study: poly (vinyl alcohol) (PVA), polyacrylamide (PAM), and (ethylene glycol) (PEG). These employed to make nanocomposites films utilizing solution dry casting techniques with varied loading ratios of Silver nanopowders (AgNPs) (0.1, 0.2, 0.4 wt. percent). The varying thicknesses (950 nm). diffusion NPs among the gaps polymer mix particles was...

A water-induced self-healing polymer hybrid was prepared by the hybridization of poly(vinyl alcohol) with smectite clay in aqueous media and subsequent casting.

   The aim of the present investigation is to synthesize Barium ferrite and Nickel ferrite Nanoparticles by co-precipitation method and these nanoparticles are used to prepare nanocomposites with poly vinyl alcohol (PVA). The composited nanoparticles are characterized by using FTIR, XRD and SEM. The synthesized nanoparticles are used as adsorbent to remove the heavy metals such as Cu2+...

Graphene oxide/poly(vinyl alcohol) (GO/PVA) composite hydrogel was prepared and utilized for selective drug release at physiological pH.
