Structure of polyethylene after pulse ion beam treatment

Abstract

Pulse ion beam treatment was employed for polyethylene (PE) surface modification. Ultraviolet, infrared (IR), IR–attenuated total reflection spectroscopy (IR–ATR), and X‐ray photoelectron spectroscopy methods, as well as wetting angle measurement, were used for the analysis of PE structural changes. Theoretical calculations and experimental data showed treated PE surfaces to have a layered structure. It was found that the upper layer contains various products of PE oxidation and the lower layer contains products of PE decomposition, that is, condensed aromatic structures. © 1998 John Wiley & Sons, Inc.

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.…”

Properties of ultra high molecular weight polyethylene fibers after ion beam treatment

“…1(b)], so it can be concluded that applied irradiation dose caused local overheating, i.e., melting followed by recrystallization, which led to the shrinking of initially ultradrawn polyethylene chains. The undestructive effect of the pulsed ion beam treatment was shown at the example of low density polyethylene film3 using XPS, UV, and IR ATR spectroscopy as well as TRIM (Transport and Range Ions in Matter) simulation 23. Thus, though the surface layer ca.…”

“…It was shown before3 that the chemical composition of the surface of commercial polyethylene film changes drastically after ion‐beam treatment carried out using the ion source. IR ATR spectra of the initial and irradiated samples of UHMWPE woven material are presented in Figure 6.…”

“…Recently modification of polymer materials by ion beam surface treatment (IBST) has drawn increasing attention of the researchers. IBST induces structural changes in the surface layer of the polymer film, the depth of the modified layer, and its chemical composition being dependent on the treatment conditions and type of the ion 3, 4. For example, in Ref 3.…”

“…IBST induces structural changes in the surface layer of the polymer film, the depth of the modified layer, and its chemical composition being dependent on the treatment conditions and type of the ion 3, 4. For example, in Ref 3. the number of crosslinks is supposed to be dependent on linear energy transformation (LET), ion energy and irradiation dose.…”
