“…They also inferred that the surface chemistry and wettability characteristics of a material could be significantly altered through exposure to atomic oxygen ions. On account of the large variations in wettability characteristics which this technique can elicit, a large amount of investigations have been carried out in to how plasma surface treatment can modulate the adhesion characteristics of materials [137,[141][142][143]. An interesting and important hypothesis came from the work of Lai et al [142] who concluded that the C=O double bond ratio was an important driver for and the wettability characteristics of polymeric θ surfaces.…”

This is of major interest as it does suggest that the bond ratio could have implications in the adhesion characteristics of the material and may need to be investigated in relation to biological and microbiological adhesion.…”

On account of the recent increase in importance of biological and microbiological adhesion in industries such as healthcare and food manufacturing many researchers are now turning to the study of materials, wettability and adhesion to develop the technology within these industries further. This is highly significant as the stem cell industry alone, for example, is currently worth £3.5 million in the United Kingdom (UK) alone. This paper reviews the current state-of-the-art techniques used for surface treatment with regards to modulating biological adhesion including laser surface treatment, plasma treatment, micro/nano printing and lithography, specifically highlighting areas of interest for further consideration by the scientific community. What is more, this review discusses the advantages and disadvantages of the current techniques enabling the assessment of the most attractive means for modulating biological adhesion, taking in to account cost effectiveness, complexity of equipment and capabilities for processing and analysis.

“…It was shown that the polyester material gained a better hydrophilicity in a short time with the generation of new function groups. According to the research of Lai et al [10] they founded that C=O, C-O, COOH and C-NH2 appeared on the polymer film under the plasma process. Furthermore, the carbonyl group was an important factor to improve the hydrophilicity; the contact angle decreased with the increase of the carbonyl.…”

Surface modification of fiber fabric sometimes needs a large volume of cold plasma to improve its efficiency. This experimental study is based on the treatment of polyamide 66 (PA66) fabrics using large contact-area glow-like plasma, which are produced in the atmospheric air without any dielectric barriers. The atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS) are adopted, respectively, to detect the surface changes in physical microstructure and the variations in the type and quantity of chemical functional groups. The results show that the PA66 fabric surface will be etched remarkably by the glow-like plasma, and the surface roughness and the surface energy are augmented. On the surface of the processed PA66 fabrics, the oxygen-containing functional groups' content rises together with the decrease on the total primary C-C and C-N bonds. After 30 seconds of sterilization by the glow-like plasmas, most of the bacterial colonies on the fabric vanish. The effectiveness of this kind of plasma treatment could last for three days in a sealed environment.

“…Noeske et al (2004) modified the polyethylene terephthalate (PET), polyamide 6 (PA6), polyvinylidenefluoride (PVDF), polyethylene (HD-PE), and polypropylene (PP) polymers surface by plasma jet treatment, revealed that hydrophilicity of polymers have been improved. Subsequently, Lai et al (2006) reported that hydrophilicity of polycarbonate, PP and PET samples were improved by microwave-induced argon plasma treatment. Similarly Hegemann et al (2003) and Cheng et al (2006) improved the surface and adhesion property of the PP, PC, PET and PMMA polymers by plasma treatment.…”

The present study describes the fabrication of polyaniline (PANI) coated high power plasma treated polypropylene (PP) filter for antibioaerosol application. PANI was synthesized by emulsion polymerization method. PP filter was modified by plasma treatment followed by coating of PANI was performed by dip coating method and successfully characterized using SEM and FT-IR analysis. Antibioaerosol property of PANI coated plasma modified PP filter was assessed against E. coli, B. subtillis and S. aureus bioaerosols. Results revealed that water absorption property of plasma modified PP filter was significantly increased (2488%) as compared to unmodified PP filter (404%). Stability study shows that PANI coating is highly stable; concentration of PANI is higher on modified PP filter than the unmodified counterpart. PANI coated modified PP filter showed higher antibacterial efficiency than unmodified filter. It revealed nearly 100% inhibition efficiency against E. coli and B. subtillis and lower for S. aureus, but completely inhibited at high PANI concentration. Bioaerosol filtration study showed that after 120 min standing both E. coli and B. subtillis were completely inhibited by PANI coated modified PP filter. It is concluded that PANI coated plasma modified PP filter is an efficient antibioaerosol agent for above mentioned bioaerosols under given reaction conditions, could be further applied in the indoor air quality control.
