摘要：
Nanocomposites of poly(BA/MMA) reinforced with up to 3 wt % grahene sheets were used as targets for laser ablation. The target was ablated using TEA CO2 laser with fluence of 1,00 J/cm(2) and thin films of crosslinked polymer/graphene with large specific surface area were obtained. The polymer-graphene deposit was covered with silver nanoparticles by excimer laser ablation in order to prepare active substrates for Surface-Enhanced Raman Scattering (SERS). The nanocomposites were characterized by means of spectroscopy, microscopy and diffraction techniques. The SERS substrate performance was tested using Rhodamine 6G as a probe compound. Highly enhanced signal was achieved, and sensoric properties of the prepared substrates were demonstrated.
