This study investigated on ligand integration effect of poly(amidoamine) (PAMAM) dendrimers working in the solid composite systems, which was significant for stabilizing Pd nanoparticles (PdNPs). To carry forward this research, the PAMAM dendrimer (typically for the fourth generation) was modified with polymerizable functions and tied to polymer networks constituting porous composites through the polymerization-induced phase separation (PIPS) strategy. The obtained results indicate that creation of PdNPs is strongly affected by the dendrimer template. Also, the crucial importance from perspective of catalytic applications is strong suppression of Pd leaching for the dendrimer-utilized porous polymer composites. All these characteristics are in marked contrast to those of the composite that was fabricated with a non-integrated, small molecule ligand system.
