Antimicrobial Polypropylene Loaded by Cubic Cuprous Oxide Micro Particles

Abstract

R ECENTLY, nanotechnology of metals and their oxides is increased and became important for production of antimicrobial textiles. In situ synthesis of micro cuprous oxide particles (Cu 2 O), 1-30 mM/L onto non-woven polypropylene and study the antimicrobial activity were investigated. Cu 2 O micro particles were prepared by chemical method using copper sulphate pentahydrate, sodium hydroxide and glucose as a reducing agent at 90 o C for 2 hrs, followed by pad-dry-cure at 150ºC for 5min. C u 2 O content onto PP was estimated before and after five washings and drying. Characterization of Cu 2 O Micro particles onto PP was done by XRD, SEM, EDX and which had revealed the presence of Cu 2 O micro particles in cubic shape, with face dimeter 0.6-0.8μm. Characterization of polypropylene color before and after Cu 2 O treatment was determined at λ max 410 nm using the colorimetric data (L*, a*, b*, ΔE) and the color strength ( K/S). The antimicrobial activity of treated PP against pathogenic microbes such S. aureus, E. coliand C. albicans was evaluated after 24 hrs contact time and gave very good antimicrobial results.

Hydrophilic cloth by surface modification of polypropylene fabrics with mineral particles

“…As the heating proceeds from an external source, the surface is first melted, then particles could be attached to it without significant changes in NWF crystal morphology. [ 19 ]…”

“…As the heating proceeds from an external source, the surface is first melted, then particles could be attached to it without significant changes in NWF crystal morphology. [19] Micrographs of modified NWF using Methodologies A and B, as well as, particles and neat NWF are presented in Figure 2. A wide particle distribution of minerals is evident from Figure 2A; meanwhile, at high magnification, zeolite-rich sectors can be distinguished over volcanic glass (Figure 2B).…”

Utilizing some synthesized nanostructured materials to improve the functional properties of cotton fabric for possible applications

“…The particle size of CuO NPs was obtained by TEM analysis figure (10), the distribution ranges of CuO NPs were approximately from 5 nm to 50 nm. This indicated that the synthesized CuO NPs were a narrow distribution of diameters and the average particle size approximately 50 nm was of achieved [21]. FTIR spectrum FTIR spectrum of the CuO NPs and pretreated CuO NPs -cotton fabric is given in figure (11).…”
