“…At the end of the grafting process, the unreacted monomers and the homopolymer formed were extracted from the obtained treated PP through repeated washing with hot water to a constant weight. The degree of grafting (%) was calculated according to the following equation

italicGraft Yield (() %) = ([], ((), W g prefix- W_{o}) true/ W_{o}) X 100

where W o and W g represent the weights of initial and grafted fibers, respectively.…”

Polypropylene fibers were treated against microbial effects by gamma radiation-induced grafting of acrylic acid, followed by metal complexation with Zn 2+ or Ag + metal ions. The treated polypropylene fibers were characterized by using Fourier transform infrared spectroscopy and scanning electron microscopy. The effect of the treatment on the thermal stability was investigated by using thermogravimetric analysis, in which a slight increase in the major thermal stability was observed. The antimicrobial activity of the treated fibers was also evaluated. On the basis of the obtained results, it was found that the antimicrobial properties of the treated fibers were enhanced both qualitatively, as indicated by the distinct inhibition zone diameter towards Gram-positive as well as Gram-negative bacterial strains under study, and quantitatively, in which 100% inhibition of Staphylococcus aureus and Escherichia coli was achieved.

“…1 Glow discharge vacuum plasma was used in pre-treating nylon for surface activation followed by grafting 2-hydroxy ethyl methacrylate (HEMA) at 7.6% add-on to increase fibers hydrophilicity [23]. Graft polymerization of glycidyl methacrylate (GMA) onto nonwoven polypropylene was achieved by radiation-induced methods [24], and plasmagraft polymerization of Kevlar 49TM followed by reaction with triethylenetetramine (TETA) as a curing agent [25]. The tail portion of a glow discharge vacuum plasma was also used for surface activation of nylon 6,6 and grafting poly (acrylic acid, PAA) followed by grafting ethylene diamine and hexylamine to PAA [26].…”

Oxidative atmospheric pressure plasma was utilized to activate surface of PA 6,6 fabrics followed by graft copolymerization of glycidyl methacrylate (GMA) and further reacted with triethylene tetramine (TETA), quaternary ammonium chitosan (HTCC) or β-cyclodextrin (β-CD). The inner CD cavity was complexed with some insecticidal perfumes. Modified PA6,6 fabrics were analyzed by differential scanning calorimetry, thermogravimetric analysis, Fourier transform infrared spectroscopy and scanning electron microscopy. Antimicrobial activity and insect repelling assay were conducted and showed efficient antimicrobial and insect repelling properties.

ABSTRACT:In this investigation, modification of polypropylene (PP) with an objective to obtain packaging film with improved gas barrier properties has been studied. The chemical reaction of PP resin with hexamethylene diisocyanate and toluene diisocyanate was monitored by Fourier transform infrared spectroscopy, wherein the appearance of new peaks at 3333 cm −1 for N H stretching, 1620-1641 cm −1 for (C O) NH stretching and 1552-1578 cm −1 corresponding to N H bending in an amide moiety was observed for both the modified PP films. Films of excellent clarity and uniform thickness were obtained by the extrusion of cross-linked polypropylene. The barrier, mechanical, optical, and thermal properties of the modified PP films were studied. The results clearly indicated significant changes in gas barrier and mechanical properties. Food

Radiation-Induced Graft Polymerization of Glycidyl Methacrylate onto Nonwoven Polypropylene

Abstract: The influence of the major grafting parameters (irradiation dose, reaction time, and inhibitor concentration) on graft polymerization of glycidyl methacrylate from its 10% solution in methanol onto nonwoven polypropylene upon irradiation with an electron accelerator in air was studied.
