Modelling of swelling of PVA hydrogels considering non-ideal mixing behaviour of PVA and water.
(Royal Society of Chemistry, 2019)
Poly(vinyl alcohol) (PVA) hydrogel microbeads are widely used as embolization agents for the treatment of cancer infiltering organs. The success of embolization procedures depends strongly on the swelling properties of the ...
Release kinetics of rosemary (Rosmarinus officinalis) polyphenols from polyvinyl alcohol (PVA) electrospun nanofibers in several food simulants
(Elsevier Ltd, 2018-12)
Polyvinyl alcohol (PVA) electrospun mats with antioxidant activity (PVA/Ros) were obtained by incorporating rosemary extract (RE) into the electrospinning precursor solution. RE compounds interact with PVA, favoring the ...
Estudio antimicrobiano de películas de quitosano-alcohol polivinílico dopadas con TiO2
(Lima (Perú)PE, 2007-08)
Se ha preparado películas de alcohol polivinílico (PVA), quitosano-PVA y quitosano-PVA dopadas con TiO2 y evaluado sus propiedades antimicrobianas frente a cepas bacterianas de S. aureus, E. coli y P. aeruginosa. Se encontró ...
The effect of the degree of hydrolysis of the PVA and the plasticizer concentration on the color, opacity, and thermal and mechanical properties of films based on PVA and gelatin blends
(ELSEVIER SCI LTD, 2008)
The objective of this work was to study the color, opacity, crystallinity, and the thermal and mechanical properties of films based on blends of gelatin and five different types of PVA [poly(vinyl alcohol)], with and without ...
Preparation and characterization of polyvinyl alcohol–pectin cryogels containing enrofloxacin and keratinase as potential transdermal delivery device
(VBRI Press AB, 2016-05-23)
Polyvinyl alcohol (PVA) and polyvinyl alcohol-pectin (PVA-P) cryogels are potential devices for wound healing. These materials have advantages over commercial wound dressings such as: retaining an appropriate level of ...
Estudo da liberação controlada de fármacos por hidrogel de PVA/Atapulgita

Hidrogéis de PVA-NaCMC para aplicação em curativos
(Universidade Federal do Rio de JaneiroBrasilEscola PolitécnicaUFRJ, 2019)
Studies on PVA pectin cryogels containing crosslinked enzyme aggregates of keratinase
(Elsevier Science, 2014-02)
Polyvinyl alcohol-pectin (PVA-P) films containing enrofloxacin and keratinase were developed to treat wounds and scars produced by burns and skin injuries. However, in order to prevent enzyme inactivation at the interface ...
Biodegradable Films Based on Blends of Gelatin and Poly (Vinyl Alcohol): Effect of PVA Type or Concentration on Some Physical Properties of Films
(SPRINGER/PLENUM PUBLISHERS, 2008)
The aim of this work was to develop biodegradable films based on blends of gelatin and poly (vinyl alcohol) (PVA), without a plasticizer. Firstly, the effect of five types of PVA with different degree of hydrolysis (DH) ...
Enzymatic transesterification of soybean oil with ethanol using lipases immobilized on highly crystalline PVA microspheres
(2013-10-07)
Polyvinyl alcohol (PVA) microspheres with different degree of crystallinity were used as solid supports for Rhizomucor miehei lipase immobilization, and the enzyme-PVA complexes were used as biocatalysts for the ...
