    • Electroless plating was carried out using a multi-step processes which included: etching, rinsing, conditioning, sensitization, activation, acceleration and electroless silver plating. MMA (5 g) beads were etched in NaOH (1 M, 500 mL) at 70°C for 4 h prior to use, rinsed in distilled water, and conditioned in a solution of PEG-1000 (1 g) and water (500 mL) for 5 min. Surface sensitization was performed by immersing these beads on an aqueous solution containing SnCl2 (2 g) and water (100 mL) for 3 min. Beads were then rinsed in a solution of PdCl2 (1 g) and distilled water (1000 mL) for 3 min, and treated with 10% HCl (the accelerator, They were then rinsed with distilled water and completely dried at 40°C. These pretreated MMA beads (0.5 g) were then dispersed in a solution of PVP (0.1 g)/methanol (40 mL) in a polypropylene container (to avoid silvering of the reaction vessel, To this dispersion was added a solution of silver 2-ethylhexylcarbamate 0.3 g

These pretreated MMA beads (0.5 g) were then dispersed in a solution of PVP (0.1 g)/methanol (40 mL) in a polypropylene container (to avoid silvering of the reaction vessel). To this dispersion was added a solution of silver 2-ethylhexylcarbamate (0.3 g, silver content 10%) in methanol (10 mL) and a solution of hydrazine (0.2 g) in methanol (10 mL) with stirring to increase the density and thickness of the silver coating for 30 min. Finally, the PMMA-Ag composites were filtered and washed with methanol by centrifugation.
