“…First, as confirmed by surface analysis (13,14), after creation and recombination of free radicals, oxy-gen containing groups are bonded to the polyethylene chains. This improves fiber wettability because of an increase in polyethylene superficial energy and allows for chemical bonding with appropriate resins.…”

The effect of plasma treatment duration on adhesion promotion of high modulus polyethylene fiber to a polyester resin matrix has been studied. The adhesion level was evaluated using pull-out tests. The relevant parameters are the average interface shear strength and the critical embedded length. Particular attention was paid to the sample preparation and testing procedure to minimize data scatter inherent to this method due in part to structural and surface defects of the fiber. The results demonstrate that adhesion is enhanced for plasma treatment times as short as 2 s, mostly because of chemical bonding. Interfacial shear resistance gradually increases for the longer times considered, up to 10 min, In the latter case, improvement may be due to fiber surface etching and roughening, rather than chemical bonding.

over the whole energy range. The plasma surface modification occurs by removal of any surface contaminants and highly oriented surface layers, the addition of polar and functional groups on the surface, and the introduction of surface roughness . These modifications enhance the polarization processes in the samples which increase the dielectric parameters following the polar dielectric behavior.…”

Carboxymethyl cellulose film doped with 40 wt% nickel chloride (NiCI2·6H2O) has been prepared by casting technique. The prepared film sample has been treated with nitrogen plasma at different exposure times. The optical absorption was recorded at room temperature in the wavelength range of 190–2,500 nm. From the absorption edge studies, the values of the Urbach energy (Ee) were found to be 0.99eV in case of the pristine film; however, the Urbach energy values were found to be in the range of 0.72–0.92 eV under different plasma treatment times. These energy values indicate that the model based on random fluctuations of the internal fields associated with structure disorder is preferable and consequently transitions occurred through localized and extended states. Modulation of refractive index and complex dielectric constants has been also studied. Variation of color parameters under effect of the plasma treatment are discussed in the frame work of CIE L* u* v* color space. POLYM.
