Micrometric acrylic beads were produced in polymethylmethacrylate foils through complex physical and technical procedures in order to enhance the absorption coefficient in the IR region. Moreover, Au nanoparticles were embedded in the polymer in order to induce surface plasmon resonance absorption and plasma electron density enhancement. The suitably prepared polymers were investigated at low laser intensity to have evidence of their capability to absorb IR wavelength radiations and promote enhancement of the plasma temperature and density. Results indicate that the high transparence of PMMA foils can be strongly reduced by the presences of the micrometric acrylic beads and that the obtainable laser-generated plasma improves the ion acceleration when high beads density and high Au nanoparticles concentrations are employed.
