Fabrication Polyvinyl alcohol - Poly-Acrylic acid/ Niobium Carbide New Bio-Films for Antibacterial Applications

Abstract

CONCLUSIONS 1-The NbC nanoparticles is aggregated as a cluster at lower concentrations. At high concentrations of NbC nanoparticles, the nanoparticles form a paths network inside the (PVA-PAA) blend. 2-The inhibition zone for S. aureus increases with increase in concentrations of NbC nanoparticles. 3-The (PVA-PAA-NbC) nanocomposites have good antibacterial activity against Staphylococcus aureus.

Antibacterial Activity of Biopolymer Blend- Carbide Nanoparticles Bio-Films against Escherichia Coli

“…Nanocomposites have properties different of the properties for the filler and matrix. The nanocomposites have applications in many fields: humidity sensors [6][7][8][9][10][11], pressure sensors and piezoelectric [12][13][14][15][16], antibacterial [17][18][19][20][21][22], thermal energy storage and release [23][24][25][26] and radiation shielding [27][28][29][30]. Carbides have been broadly used in numerous fields, for instance composite ceramic materials, aerospace materials and wear resistance, because it has high melting temperature, high hardness, oxidation resistant, high thermal shock resistance and high abrasion resistance [31].…”

UV-Absorption for Biological Application of (PolymerCarbide) Nanocomposites

“…However, these application areas continuously demand additional properties and functions such as high mechanical properties, flame retardation, chemical resistance, UV resistance, electric conductivity, environmental stability, water repellency, magnetic field resistance, radar absorption [4][5][6][7]. The nanocomposites are used in fields such as: humidity sensors [8][9][10], pressure sensors and piezoelectric applications [11][12][13][14], antibacterial [15][16][17][18][19][20], thermal energy storage and release [21][22] and radiation shielding [23][24]. Carbides have been broadly used in numerous fields, for instance composite ceramic materials, aerospace materials and wear resistance, because it has high melting temperature, high hardness, oxidation resistant, high thermal shock resistance and high abrasion resistance [25].…”
