“…Cyclohexane plasma may increase the compatibility and intimate molecular contact between the polypropylene and cellulose, but the lack of hydrogen and/or covalent bonding results in no strength development in the laminated structures. This reinforces the idea that polarity plays a significant role in the overall strength of these types of composites [22].…”

“…Using this method, a 180% increase was obtained (from 5 to 13 g/cm), which was likely provided by hydrogen bonding and correlated with the highest level of CAOH bonding that was introduced onto the PET surface [21]. A similar result was obtained for the oxygen and argon plasma treated polypropylene (PP) [22]. Another strategy to improve the adhesion between cellulose and PP was based on the modification of the cellulose surface via the deposition of a hydrophobic polymer layer using cyclohexane plasma polymerization.…”

“…This interpretation is confirmed by the weaker peel strength obtained for the laminates prepared from the cellulose coated with poly(L-lactide-g-vinyl alcohol) copolymer in which only entanglements and polar interactions take place. Comparatively, the air, oxygen, argon, nitrogen and monomer plasma treatments of cellulose developed in the literature enhance either functionalization or compatibility with a hydrophobic polymer resulting in moderate adhesion [20,22]. Plasma-induced grafting of L-lactide may contribute to a better understanding of the nature of requisite interfacial interactions to improve adhesion.…”

“…Cold plasma is already a very effective method to modify the surface of natural polymers without changing their bulk properties . This method has been used to increase adhesion and compatibility between two polymers [37][38][39]. Physical treatments change structural and surface properties of the fiber and influence the mechanical bonding with the matrix.…”

Abstract:Plants, such as flax, cotton, hemp, jute , sisal, kenaf, coir, pineapple , ramie, bamboo , banana, as well as wood, are a source of lignocellulosic fibers. Their availability, renewability, low density and price as well as satisfactory mechanical properties make them attractive reinforcing fibers in the manufacture of composites . The natural fiber containing composites are used in transportation (automobiles , railway coaches, aero-space), military applications, building and construction industries (ceiling paneling, partition boards), packaging, and consumer products. INTRODUCTIONNatural fiber reinforced composites can be divided into groups: 1) conventional panel type composites where lignocellulosics serve as the main ingredient, e.g., particleboards, fiberboards, and insulation boards, with organic binding materials, including natural binders like lignin and tannin; 2) lignocellulosic-mineral composites which are based on inorganic binding materials; 3) natural fiber reinforced polymers, in which the lignocellulosics serve as reinforcing fillers within matrix materials such as thermoplastics , thermosetting plastics and rubbers; and 4) nonwoven textile type composites.The most important natural fiber composites are listed in Table 1 [1, 2]. The properties of composites depend on those of the individual components and on their interfacial compatibility . CONVENTIONAL COMPOSITE BOARDSConventional composites fall into two main categories based on the physical configuration of the lignocellulosics: particleboards and fiberboards. Within each category are low, medium, and high density classifications. Also, both wet and dry processes are used for each category of composite. Conventional composites typically use a heat-curing adhesive to hold the lignocellulosic component together [3].Table1. Composites ParticleboardsThe main lignocellulosic raw material used in the particle and fiberboard industries is wood, but in many countries other agriculturally based materials are successfully utilized. Annual plant waste such as flax and hemp shives, jute stalks, bagasse, reed stalks, cotton stalks, grass-like Miscantus, vetiver roots, rape straw, oil flax straw, small grain straw, peanut husks, rice husks, grapevine stalks and palm stalks are cheap and valuable raw materials for lignocellulosic board production.The production technology is similar to that for lignocellulosic board production from wood particles. All particleboards are currently made using the dry process, in which air is used to randomize and distribute the particles prior to pressing. The specifics of board production from annual plant waste are concerned with raw material preparation, including purification and sorting of the material [I, 2].One of the most important advantages of these boards is the ability to produce a wide spectrum of densities from 300 to 750 kg/m' (see Table 2). Annual plant waste boards are mainly used in the building and furniture making industries, and in transportation [4]. Particleboards, readily made from a vari...

“…Gas plasma treatment of fibres is the next possibility of cellulose fibre surface activation for later chitosan adsorption. Cold plasma treatment is an extremely versatile technique for modifying the polymer surfaces of totally different shapes (Clark 1979et al, Wertheimer et al 1996, Kunaver et al 2004, Mozetic 2004, Morales et al 2006, Sharnina et al 1996, Tu et al 1994, Prabaharan et al 2005. It has been reported that plasma treatment can improve polymer-polymer adhesion (Clark et al 1979, Wertheimer et al 1996, the best results being obtained when using oxygen plasma (Carlsson 1991, Felix et al 1994, Couto et al 2002.…”
