Ion beam modification of polyethylene and adhesion to epoxy adhesive

Raman scattering of ultra-high molecular weight polyethylene treated by plasma-based ion implantation

“…Adverse effects like post-treatment oxidation set severe limitations to their applicability. In the last few years, it was also demonstrated that ion bombardment could also lead to significant improvement of the surface properties of polyethylene [3][4][5]. It is well known that ion bombardment significantly alters both the chemical composition and the structure of a polymer and in particular of polyethylene [5].…”

“…The energy transferred to the material, in addition to compositional and structural changes, induces sufficient heat, which may rise the temperature of the polyethylene target, even above the melting point. To eliminate problems connected with heating, pulsed ion beam was used [4] instead of a continuous one. Results on the feasible application of the plasma-based ion implantation have also been published [3].…”

“…Many attempts, involving physical and chemical interactions, have been made to improve the surface chemical and mechanical properties of polyethylene [1][2][3][4][5][6]. Irradiations by gamma photon and electron beams are among the most often used physical means and chemical agents improving cross-linking of the polymer chains were also applied.…”

Surface attachment of horseradish peroxidase to nylon modified by plasma‐immersion ion implantation

“…Ion‐beam implantation and PIII have been used for the modification of polyethylene, 13–21 polystyrene, 22–28 polytetrafluoroethylene, 29–34 poly(ethylene terephthalate), 35–38 poly(methyl methacrylate), 39–42 polyurethane, 43–47 and other polymers. Leading to increases in the hardness, electrical conductivity, and wettability, structural changes typical of ion‐irradiated polymers, such as carbonization, depolymerization, and oxidation, have been observed.…”

Adhesion

“…Such a model of the adhesion joints was applied for adhesion joints of different kinds of polymers at UV light, plasma discharge and ion beam modifications [11][12]. The initial strength of a joint is close to the strength of one of the polymers ( 0 = 1 ).…”
