“…Ultrahigh molecular weight polyethylene (UHMWPE) is a useful material in medicine, engineering, microelectronics, biology, etc. Irradiation and ion implantation by C, N, O, Ne and Si ions of polymeric materials reveal improvements in their surface properties [2][3][4]. However, only few reports are known on the influence of fast atom beam treatment (FAB) on the surface properties of polymers [5][6][7].…”

“…The absorption, fluorescence, and phosphorescence phenomena become possible only owing to the appearance of defect electronic levels localized in the energy gap. Such defects may include diene and polyene structures [22][23][24][25]. They can arise as a result of the interaction between the macromolecules and the fillers, first of all in the considered immobilized layers.…”

Дослiджено динамiчнi модулi пружностi, зсуву в нанокомпозитах полiетилену низької густини з багатостiнними вуглецевими нанотрубками (ПЕНГ-БВНТ). Показано, що поведiнка динамiчного модуля пружностi Юнга E′ та модуля зсуву G′ при збiльшеннi концентрацiї нанотрубок має немонотонний характер. Зi збiльшенням вмiсту БВНТ важливу роль вiдiграє орiєнтацiйна структурованiсть макромолекул, адсорбованих на нанотрубках. Це супроводжується перебудовою коливних спектрiв та електронної структури i, як наслiдок, може впливати на покращення фiзико-механiчних та транспортних властивостей вказаних нанокомпозитiв.

“…ion beam)-linear energy transfer (LET) radiation has been extensively studied. [4][5][6][7][8][9][10][11][12][13][14][15][16][17] Ion beam seems to be a very promising option due to its large LET as well as its ease adjusting of penetration depth. The damage processes triggered by low-LET radiation can be different from those induced by high-LET radiation.…”

In the present work, ultra-high-molecular-weight polyethylene (UHMWPE) films were irradiated with 130 keV He ions. The fluence of the ion beam was ranged from 1 × 10 12 to 1 × 10 16 cm −2 . The chemical, morphological, and crystallite structure changes resulted from the ion bombardment were obtained using different spectroscopic techniques. These techniques were Fourier transform infrared spectrometer, scanning electron microscope, X-ray diffraction, and UV-vis spectrophotometry. The surface free energy for untreated and ion-beam-treated samples was determined by means of contact angle measurements of three different liquids. Our results showed a decrease in the crystallinity of UHMWPE and formation of C=O groups on the polymer surface for modified samples as well. A remarkable shifting in the UV-vis spectra toward lower energy and increase in the optical absorption were observed as the ion fluence increases. Measurements of the contact angle indicate remarkable increase in the surface free energy as a function of ion fluence.
