Abstract
Experimental investigations of a diblock copolymer (polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) film doped selectively with tetrakis(4-carboxyphenyl)porphine (TCPP) into the nanoscale spherical domains of P4VP) used as target in a Nd: YAG laser (l = 532 nm) ablation process, were performed. The ionic current oscillations and the velocity of diblock copolymer plasma plume were experimentally obtained . Keywords: polymer, laser ablation
