Thin polymer layers consisting of a polyimide matrix with bismuth nanoparticles were synthesized in situ by hydrogen reduction using an ion-doped precursor. The mean nanoparticle size could be systematically controlled from 12 to 25 nm simply by variation of the heat treatment temperature. These relatively large nanoparticles have a narrow size distribution with a standard deviation of almost 10%. The melting temperature of the embedded bismuth nanoparticles decreased as the particle size decreased, which suggests that the nanocomposite could be utilized as a phase change composite material.
