In the article «Influence of Ultraviolet Radiation Exposure Time on Styrene-Ethylene-Butadiene-Styrene (SEBS) Copolymer» Daniel Garcia-Garcia , José Enrique Crespo-Amorós, Francisco Parres and María Dolores Samper describe how they studied the effect of ultraviolet radiation on styrene-ethylene-butadiene-styrene (SEBS) at different exposure times in order to obtain a better understanding of the mechanism of ageing.*
The results obtained for the SEBS, in relation to the duration of exposure, showed superficial changes that cause a decrease in the surface energy (s) and, therefore, a decrease in surface roughness. This led to a reduction in mechanical performance, decreasing the tensile strength by about 50% for exposure times of around 200 hours.*
NanoWorld Pointprobe® NCH AFM probes were used in the Atomic force microscopy (AFM) applied to determine the surface topography and roughness of the aged samples.
