Estudo da estabilidade físico-química do sabonete em barra contendo o álcool polivinílico (PVA)Study of the physical-chemical stability of bar soap containing polyvinyl alcohol (PVA)
(Universidade Federal de UberlândiaBrasilQuímica Industrial, 2020)
The effect of the annealing on the poly(vinyl alcohol) obtained by freezing-thawing
(Elsevier Science, 2011-07-30)
In the present work poly(vinyl alcohol) (PVA) hydrogels were obtained by freezing/thawing technique. The effect of thermal treatment on its performance was studied by annealing the hydrogels at five different temperatures, ...
Influence of Poly(Vinyl Alcohol) (PVA) on the Cyclic-Voltammetry Behavior of Single-Crystal Pt Surfaces in Aqueous H(2)SO(4)
(ELECTROCHEMICAL SOC INC, 2011)
In the present work we investigated the electrochemical behavior of PVA on polycrystalline Pt and single-crystal Pt electrodes. PVA hampered the characteristic hydrogen UPD and anion adsorption on all investigated surfaces, ...
Preparation of Poly(vinyl Alcohol) Microparticles for Freeze Protection of Sensitive Fruit Crops
(2022-06)
Poly(vinyl alcohol) (PVA) displays ice recrystallization inhibition (IRI) properties as many antifreeze proteins found in cold tolerant organisms. The molecular architecture and composition (molecular weight and distribution ...
Nitric oxide-releasing poly(vinyl alcohol) film for increasing dermal vasodilation
(Elsevier Science BvAmsterdamHolanda, 2014)
Biodegradation of blend films PVA/PVC, PVA/PCL in soil and soil with landfill leachate
(Brazilian Archives of Biology and Technology, 2011-12-01)
This study investigated the biodegradation of blends films of poly(vinyl alcohol)/poly(vinyl chloride) (PVA/PVC) and poly(vinyl alcohol)/poly(caprolactone) (PVA/PCL) blends films prepared with dimethylformamide under a ...
Biodegradation of blend films PVA/PVC, PVA/PCL in soil and soil with landfill leachate

This study investigated the biodegradation of blends films of poly(vinyl alcohol)/poly(vinyl chloride) (PVA/PVC) and poly(vinyl alcohol)/poly(caprolactone) (PVA/PCL) blends films prepared with dimethylformamide under a ...
An environmentally friendly triphasic catalytic system: Mn(salen) occluded in membranes based on PDMS/PVA
(ELSEVIER SCIENCE BV, 2010)
The commercially available Jacobsen catalyst, Mn(salen), was occluded in hybrid polymeric membranes based on poly(dimethylsiloxane) (PDMS) and poly(vinyl alcohol) (PVA). The obtained systems were characterized by UV-vis ...
Biopolymeric pellets of polyvinyl alcohol and alginate for the encapsulation of Ib-M6 peptide and its antimicrobial activity against E. coli
(Elsevier, 2019-06)
The encapsulation of Ib-M6 antibacterial peptide in pellets of polyvinyl alcohol (PVA) and polyvinyl alcohol-alginate (PVA-Alg) matrices was carried out in order to explore its controlled release and activity against ...
Influence of Triton X-100 on PVA Fibres Production by the Electrospinning Technique
