Spectroscopic studies on Ag–polyvinyl alcohol nanocomposite films

Synthesis, characterisation and antibacterial activity of PVA/TEOS/Ag-Np hybrid thin films

“…6a-b). The appearance of absorption bands at this wavelength indicates the formation of spherical AgNps [19][20] which is in an accordance with the TEM observations. In both the cases, the absorption of the silver nanoparticles becomes stronger with increasing the silver content from 0.1% up to 0.4%.…”

“…Incorporation of silver nanoparticles in PVA polymer matrix could provide antibacterial activity, which is highly desirable in medical field. Various methods including solvent evaporation, electron radiation, UV light, thermal annealing, and in situ chemical reduction have been proposed for the synthesis of materials based on PVA/silver nanoparticles [17][18][19][20][21][22][23][24][25][26][27][28] which yields different morphology and sizes of silver depending on the preparation method. PVA is very sensitive towards moisture and as a result reduces the film strength [16] that is highly undesirable of the films used for biomedical applications.…”

Fabrication and Properties of Alkaline Lignin / Poly (Vinyl Alcohol) Blend Membranes

“…It is also used as an emulsifier and a stabilizer for colloid suspensions and as a sizing agent and coating in the textile and paper industries (Chiellini et al 2003;Yamaoka et al 1995). Also PVA has film-forming capacity and could be used in blends and composites with other polymers or inorganic materials, most of which have wide applications (Bai et al 2007;Karthikeyan 2005;Lebrun et al 2004;Tang et al 2008).…”
