Polyethylene film welding induced by a 532 nm pulsed laser (original) (raw)

Radiation Effects and Defects in Solids, 2010

Abstract

A Nd:YAG laser operating at 532 nm wavelength, 3 ns pulse duration, 150 mJ pulse energy and 10 Hz repetition rate is employed to irradiate in air polyethylene-based polymers and to induce thin film welding. Polyethylene thin films of different densities, with and without enclosed carbon nanotubes, have been irradiated at different exposition times. Measurements of static tensile, shear stress and morphology permitted us
