Multiwalled carbon nanotubes(MWNTs) have the excellent mechanical, electrical, thermal, and optical properties. Palladium nanoparticles with POSS (Pd-POSS) are good candidate for chemical, optical, magnetic, and electronic devices with useful properties. Organic-inorganic hybrid nanocomposites have high performances regarding the thermal stability, mechanical property, high gas barrier, flame resistance, transparency, and excellent solvent resistance property. In this study, we have prepared the composite of poly(acrylic acid)-grafted MWNTs (PAA-MWNTs) and POSS-NH3+ (MWNT-POSS) through the ionic interaction between positively charged POSS-NH3+ and negatively charged PAA-MWNTs. POSS-NH3+ was physically attached to the surfaces of PAA-MWNTs to make MWNT-POSS. MWNT/Pd-POSS was produced from the reaction of MWNT-POSS and palladium(Ⅱ) acetate in methanol at room temperature. The characteristics of the hybrid nanocomposites (MWNT/Pd-POSS) were characterized by various analytical tools.
