Modifications in the correlation function in poly(vinyl alcohol)/silica hybrid wet gels
(Wiley-Blackwell Publishing, Inc, 2009-02-01)
Small-angle X-ray scattering was used to study structural modifications in tetraethoxysilane-derived poly(vinyl alcohol) (PVA)/silica hybrids. The basic structure of the wet gels can be described as a mass-fractal structure ...
Gas sensor for ammonia detection based on poly(vinyl alcohol) and polyaniline electrospun
(Wiley-Blackwell, 2019-04-05)
In this article, the results of the process and fabrication of ammonia gas sensors are obtained through the production of poly(vinyl alcohol) and polyaniline (PVA/PANI) nanofibers in different concentrations deposited on ...
Dynamic mechanical and dielectric relaxations in poly(di-n-chloroalkylitaconates)
(ELSEVIER SCI LTD, 2004)
Dielectric and viscoelastic relaxation measurements have been carried out on poly(2-chloroethyl diitaconate) (PDCEI) and poly(3-chloropropyl diitaconate) (PDCPI) between 123 K and temperatures about 293 K above the glass ...
Coating of Cotton Yarn with Poly(vinyl alcohol) and Poly(N-vinyl-2-pyrrolidone) Crosslinked via Ultraviolet Radiation
(JOHN WILEY & SONS INC, 2011)
The coating of cotton fiber is used in the textile industry to increase the mechanical resistance of the yarn and their resistance to vibration, friction, impact, and elongation, which are some of the forces to which the ...
Synthetic Three-Dimensional Scaffold for Application in the Regeneration of Bone Tissue
(Scientific Research Publisinhg, 2018-09)
Bone tissue engineering aims to use biodegrade.able scaffolds to replace damaged tissue. This scaffold must be gradually degraded and replaced by tissue as similar as possible to the original one. In this work a hybrid ...
The effect of molecular weight and hydrolysis degree of poly(vinyl alcohol)(PVA) on the thermal and mechanical properties of poly(lactic acid)/PVA blends
(Associação Brasileira de Polímeros, 2018-06)
The effect of molecular weights and hydrolysis degrees (HD) of polyvinyl alcohol (PVA) on thermal and mechanical properties and crystallinity of polylactic acid (PLA)/PVA blends was investigated. Blends were prepared by ...
Structural and magnetic behavior of ferrogels obtained by freezing thawing of polyvinyl alcohol/poly(acrylic acid) (PAA)-coated iron oxide nanoparticles
(Pergamon-elsevier Science LtdOxfordInglaterra, 2013)
Poly(vinyl alcohol) and poly(vinylpyrrolidone) blends: 2. Study of relaxations by dynamic mechanical analysis
(Elsevier Sci LtdOxfordInglaterra, 1999)
Effects of poly(vinyl alcohol) additions on the structure of silica xerogels
(Elsevier B.V., 2009-09-01)
Poly(vinyl alcohol)/silica hybrid xerogels were prepared from sonohydrolysis of tetraethoxysilane (TEOS) and additions of water-solution of poly(vinyl alcohol) (PVA). The samples were Studied by small-angle X-ray scattering ...
