Influence of artificially accelerated ageing on the adhesive joint of plasma treated polymer materials

Czechoslovak Journal of Physics (impact factor: 0.42). 05/2012; 54:C533-C538. DOI:10.1007/BF03166446 pp.C533-C538

ABSTRACT An influence of simulated ageing on the adhesive joint of plasma treated polyethylene (PE) and polypropylene (PP) was tested.
Plasma surface treatment was performed in the rf-plasma reactor operating at 13,56 MHz. The simulated ageing of prepared specimens
for following tensile testing was carried out under conditions given by Volkswagen standard P-VW 1200. Temperature of ageing
was regularly oscillating between −40°C and 80°C (relative humidity 80%) for required time. The mechanical tensile properties
of adhesive joint were measured according to the standard ISO 527. Surface analysis of treated polymer substrates was characterized
by XPS measurement. The observation of surface structure and morphology was obtained using SEM. We used convenient cyanoacrylate
adhesive Loctite E 406 for PE and PP joints. Tested adhesive joints were prepared in compliance with the standard ISO 4587.
