Synthesis, Characterization and Thermal Properties of Phenol-formaldehyde Polymer Based Nickel Nanoparticles

In this scientific research, thermally stable nickel nanoparticles were synthesized and characterized. Nickel nanoparticles were synthesized using phenol –formaldehyde by chemical method followed by calcination. The polymer metal complex was confirmed by FTIR and NMR. The spherical morphology of nickel nanoparticles confirmed by SEM. The crystallographic structure is confirmed by XRD and size of cobalt nanoparticles is 24.0 nm. The TGA analysis was performed over a range of 29-600OC. The TGA thermograph predicts mass decomposition of 11%, for nickel phenol-formaldehyde nanocomposite. The decomposition rate of composites is very low 2% weight loss per 100OC increment in temperature.

Chemical modification utilizing a terminal structure exposed on the specific surface of polymer-metal complex nanocrystals

We modified the surface of polymer metal complex nanocrystals (PMC NCs) with the alkylation reaction by utilizing coordinatively unsaturated bipyridine ligands exposed on the (010), and successfully changed the luminescence properties of PMC NCs.

Attempt to visualize terminal structure on a specific facet in polymer–metal complex nanocrystals

We have successfully visualized the surface terminal structure of polymer–metal complex [{Cu2(μ-Br)2(PPh3)2}(μ-bpy)]n nanocrystals (NCs) using Prussian blue (PB) nanoparticles (NPs).
