Summary Pulsed laser, such as the second harmonic emission of a Nd+:YAG laser at 532 nm, is used for surface modification of composite material consisting of elastomer and carbon black. Morphology and chemical compositions of the composite were probed by scanning electron microscopy (SEM). Microstructures such as conical, flat conical and dome-like structures were produced on the ablated surface at a pulse energy of 23 mJ/pulse and pulse width of 10 ns. For each of these microstructures, the origin of the ablated process is particularly addressed and a model describing their nucleation and growth process is proposed.
Keywords Nd+:YAG laser, composite polymer, carbon black, ablation, surface microstructure.
