“…The solvent total surface tension was measured by Wilhelmy method and compared with literature data. Table 2 reports the literature surface tensions of the tested liquids with their relative disperse and polar components [36][37][38][39][40][41][42]. The choice of the more suitable solvents for each siloxane film was made on the grounds of both numerical elaborations (total surface tension and polar/disperse ratio) and chemical compatibility; for example, toluene and diethylene glycol, in some cases, dissolved the siloxane layer and they were consequently not considered.…”

“…The hydrophilic, polar fibers show incompatibility with the hydrophobic, non-polar matrix. The interfacial adhesion between fiber and matrix may be improved using physical (corona, plasma, electron beam or UV-treatment) and/or chemical (maleic anhydride, organosilanes, isocyanates, sodium hydroxide, permanganate and peroxide) treatments [5,[13][14][15]. Maleic anhydride (MA) treatment in form of maleic anhydride-polypropylene (MAPP) copolymer was found to be the best for improving the mechanical properties of cellulose fiber reinforced PP [16].…”

Mechanical properties of hemp fiber reinforced polypropylene were investigated. Hemp fibers were carded together with polypropylene fibers, and needle punched. Composites were prepared by hot pressing of the PP/hemp mats. Hemp content was varied between 0 and 50 % by weight, in 10% steps. A treatment with two different maleic anhydride grafted polypropylenes was applied in order to increase the fiber/matrix surface adhesion. Tensile, three-point bending and Charpy tests were carried out on the treated and untreated composites.

The aim of this study was to investigate the adhesion behavior of polyphenylquinoxaline (PPQ) foils. PPQ foils were initially produced and then annealed in vacuum furnace at different temperatures. The surface of PPQ was activated with GHz-low pressure plasma (lp-plasma) using oxidative (O 2 ) and noble (Ar, Ar=He) gases. An epoxy adhesive was used to glue the PPQ foil with a sheet of steel. The adhesions of foils were examined using 90 -peel test. Observations from scanning electron microscopy (SEM) and atomic force microscopy (AFM) in addition to the gravimetry measurements were used to interpretate the effects of plasma treatment of adhesion of foils. The results showed that the peeling resistance values were significantly dependent on plasma treatment time and power as well as annealing conditions. In case of PPQ foils where the adhesion was significantly enhanced, it was observed that the fracture changed from adhesion mode at the interface between the adhesive layer and the PPQ foil to cohesive mode, which was seen either in the layer nearby the PPQ surfaces or in the foil itself. Furthermore, furrowed structures were observed at the fracture surface and they were oriented transversely to the peeling direction. SEM and AFM graphs showed that the surface roughness of PPQ foils increased significantly with increasing plasma treatment time and it was more pronounced when using oxidative than noble gas.
