Polyethylene (PE) is characterized by low surface energy as a consequence of its non-polar nature. This characteristic is responsible for poor adhesion properties on polyethylene substrates. It is well known that some industrial applications such as coating, painting and formation of adhesion joints require high surface energy to promote good anchorages, so that, the use of polyethylene in these applications needs a previous surface treatment. In this work atmospheric plasma has been used to promote surface activation on polyethylene substrates for improved adhesion properties. The work has been focused on analyzing the influence of some variables (treatment rate and nozzle-sample distance) on mechanical performance of PE-PE adhesion joints subjected to shear and T-peel tests.

“…Depending on the type and nature of the gases used, different varieties of surface modifications can be achieved. Improved interfacial adhesion and mechanical properties of bio-composites have been reported using plasma techniques (43)(44)(45)(46)(47)(48). More recently, the combination of chemical pretreatments, like alcohol with plasma treatment has been found to be effective to reduce the surface hydrophilicity of natural fibers and thus enhance the interface strength of the composites (49)(50)(51).…”

“…Physical methods like steam explosion and thermo-mechanical processes are used to separate natural fiber bundles into individual filaments, while plasma, corona and dielectric barrier techniques are to modify the surface structure of the fibers (41). Plasma treatment is a clean and environmentally friendly method, allowing significant surface modifications of fibers such as cleaning, etching, deposition and polymerization (42,43). The etching effect of plasma can increase the surface roughness of fibers and enhance the mechanical interlocking between fiber and matrix.…”

Lightweight composites produced from renewable and biodegradable materials have been very promising to find wide applications in automotive industries and to lessen the dependence on exhausting petroleum resource. In this chapter, various natural fibers, traditional polymer and bio-polymer matrix systems are presented. Potentials and limitations of modification methods on natural fiber and manufacturing techniques for lightweight composites are reviewed in details. Major technical concerns and challenges regarding natural fiber reinforced composites are addressed. Examples of recent automotive industrial applications are given and future trends are outlined.

“…In the last decades, the application of cold plasmas to modify the surface properties of textile materials is experiencing rapid growth (Chen et al 2008;De Geyter et al 2006;Morent et al 2008;Samanta et al 2009). Non-thermal plasmas are able to alter the physico-chemical properties of a polymer surface: the main effects of interaction between active plasma species and polymeric surfaces is breaking polymer molecular chains, inducing new functional groups and altering morphological properties (Caiazzo et al 1996;Keil et al 1998;Toufik et al 2002).…”

This paper focuses on the modification of cotton fabrics using a low pressure DC glow discharge obtained in air. The influence of different operating parameters such as treatment time, discharge power and operating pressure on the chemical and physical properties of the cotton fabrics is studied in detail. Surface analysis and characterization of the plasma-treated cotton fabrics is performed using vertical wicking experiments, X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and weight loss measurements. The cotton fabrics show a significant increase in wicking behaviour; an effect which increases with increasing treatment time, increasing discharge power and increasing pressure. Results also show that low pressure DC glow treatment leads to surface erosion of the cellulose fibres, accompanied by an incorporation of oxygen-containing groups (C-O, C=O, O-C-O and O-C=O) on the cotton fibres. The DC glow treatment has thus the potential to influence not only the chemical but also the physical properties of cotton fabrics and this without the use of water or chemicals.
