“…Plasma treatment of polymer surfaces-a technique used for modifying the surface properties without modifying the bulk properties 2 -enhances the adhesion properties 3,4 and particularly improves biocompatibility 5,6 and metal adhesion. 7,8 The presence of surface species (radicals and functional groups) also can initiate a post-grafting reaction of any kind of vinyl monomer 9,10 or allows the covalent attachment of specific species (chelating molecule or catalyst, for example 11,12 ).…”

High-density polyethylene (HDPE) and polypropylene (PP) films were analysed by time-of-flight secondary ion mass spectrometry (ToF-SIMS) in a quantitative way in order to study chemical modifications produced by CO 2 plasma surface treatments. Although there are many works devoted to the study of surface modification by plasma treatments, this contribution aims at proving the SIMS ability to quantify superficial functions.For that purpose, results obtained by spectrochemical titration (fluorescence labelling with thionine acetate), XPS measurement and ToF-SIMS analyses were compared. The results obtained with these three different techniques showed the same behaviour, i.e. a fast carboxylic functionalization of the polymer surface with the plasma treatment time.The good correlation between the spectrochemical titration and ToF-SIMS results brings out clearly the capacity of the ToF-SIMS technique to quantify surface chemical species. But this requires that we should be able to identify the secondary ions originating from the studied functions.

“…Surface treatment of carbon fibers, such as anodization [2][3][4][5][6][7] or plasma [8][9][10][11][12][13][14] or γ-ray [15,16] treatment, is conventionally used to improve the bonding strength between the carbon fiber and epoxy resin. Park et al [2] showed that the anodic oxidation of carbon fibers led to an increase in the surface free energy of the fibers and played an important role in enhancing adhesion at the interfaces between the fibers and resin matrix.…”

“…Other researchers have investigated the effects of various plasma surface treatments, such as nitrogen, argon, oxygen, and tetrafluoromethane treatments, on carbon fiber surfaces [8][9][10][11][12]. Bogoeva-Gaceva et al [8] showed that plasma treatment increased the IFSS of fiber-epoxy composites by more than 10% relative to that of an untreated composite.…”

“…Lin and Yip [11] posited that nitrogen surface functionalities could easily be formed by nitrogen ion bombardment, and the treated carbon fiber composites exhibited higher transverse tensile stress. Bian et al [12] reported that oxygen and nitrogen/hydrogen plasma treatments were the most effective for introducing oxygen-containing functionalities on the fiber surface and for improving the IFSS of the composites with the treated fibers. Another plasma approach is copolymerization of the carbon surface by acrylic acid-hexane, allyl alcohol-hexane, or allylamine-octadiene [13][14].…”

Matrix resins of carbon fiber-epoxy composites with different numbers of epoxy functional groups were prepared, and their properties were compared to optimize the matrix resin composition. To understand the bonding strengths between the carbon fiber and epoxy resins in monofilaments and micro-sized resin beads, the interfacial shear strength (IFSS) was measured using the microdroplet technique. The bonding strength for the T800SC carbon fibers was maximized for a 50:50 (wt/wt) ratio of epoxy resins containing four and three epoxy groups per molecule, respectively, and that for the IMS60 carbon fibers was maximized for a 70:25:5 (wt/wt/wt) ratio of epoxy resins containing four, three, and two epoxy groups per molecule, respectively. The transverse tensile, in-plane shear, interlaminar shear, and compression strengths were higher for the interfacial-shear-strength-optimized T800SC-epoxy mixture than for the T800SC-100% basic bisphenol A epoxy material. These composite materials exhibit a potential to be used in applications such as automobiles and aircraft as lightweight, high-strength, and rigid materials.
