“…At the moment when sufficient charges accumulate to break the dielectric strength of the gas, a micro discharge occurs at that point, which is a kind of plasma 8 . Other types of plasma commonly used to treat the surface of polymeric materials are based on the use of low pressures, 9 radio frequency 10 or microwaves, 11 which can hinder the process because they are techniques that require more severe operational conditions.…”

The modification of the surface characteristics after treatment with plasma in polymeric materials, such as the aging phenomenon, calls the attention of research in the area of nonthermal plasma technology. In this work, a direct treatment with dielectric-barrier discharge plasma was used on the surfaces of ultrafiltration membranes. The measurements of the contact angle with water, attenuated total reflectance accessory, zeta potential, atomic force microscopy and scanning electron microscopy-MEV were performed on the surfaces to verify changes after plasma treatment and to understand the occurrence and timing of the plasma aging effect. In the analysis of the membrane performance, hydraulic permeation and protein retention tests were performed. The results showed an improvement in wettability and hydrophilic properties in the post-treated membranes. The study of reversibility/aging of the postplasma surface is important for research that deals with the modification of polymeric membranes. Changes in surface morphology, topography and wettability of the membranes were observed up to seven days after treatment, with a tendency to return to the initial characteristics of the membranes.

“…14 The peaks at 2850 and 2920 cm –1 corresponded to the C–H stretching, and the peaks at 1452 and 1490 cm –1 were related to the C–H bending. 13,17 The C–H groups of PM and PBM were resulted from an acrylic acid binder, while for the CGM and PCGM, the groups were resulted from both the binder and the TPMMC. While, as grafted onto the glass fiber, the TPMMC only existed in the samples of CGM and PCGM.…”

This paper reports a novel glass fiber membrane with an effective antibacterial performance by chemical grafting of quaternary ammonium salt (QAS) which is enhanced by a plasma bombardment technique. Plasma bombardment as a pretreatment of the membrane can increase the QAS anchored on the membrane from 0.8 to 1.3 wt %. The chemical grafting technique can increase the membrane zeta potential from negative values to positive values in aqueous solutions at various pHs. Furthermore, the plasma-enhanced chemical-grafting membrane has more positive zeta potentials (49.0 mV at pH = 7) than the chemical-grafting membrane without the plasma bombardment technique (38.9 mV at pH = 7). In the antibacterial performance evaluation, the Escherichia coli survival rate decreased from 127.0% of the pristine membrane to 4.1 and 11.3% of the plasma-enhanced chemical-grafting membrane and the chemical-grafting membrane, respectively. In addition, the plasma-enhanced chemical-grafting membrane shows durable antibacterial activity against E. coli with copious water rinsing as much as 3 L·cm–2.

P OLYPROPYLENE (PP) is a cheap fabric, bearing chemical resistance and excellent mechanical properties. PP is hydrophobic in nature, inactive synthetic fabric due to the absence of reactive functional groups in the molecular structure, thus preventing its dyeing. For this reason, PP fibers are modified by irradiation methods to form free radical centers onto the surface and graft copolymerization of selected vinyl monomers. Different irradiation techniques are adopted involving plasma discharge, electron beams, ozone, UV, γ-rays and others. PP is grafted with selected monomers including methacrylate derivatives such as (2N-Dimethyl amino ethyl methacrylate, 2N morpholino ethyl methacrylate, 2-ethyl methacrylate phosphoric acid, methyl methacrylate, 2-hydroxy ethyl methacrylate) acrylic acid, styrene, chloro methyl styrene, vinyl acetate etc... The different variable factors affecting irradiation and grafting reactions are considered such as irradiation dose, storage time of irradiated fabric, monomer concentration, reaction time and temperature. Physical properties of grafted and those containing tertiary amino quaternized groups are improved for increase of moisture regain, melting point and enhancement affinity to dyeing by different classes of dyestuffs. The important properties improvement include ion exchange capacity, electrical conductivity, antistatic, insect repellent activity antibacterial property. PP containing Ag, Zn, ZnO, TiO 2 , Cu, Cu 2 O nano particles are antibacterial fabrics which are used as wound healing dressings.
