Abstract
Diblock copolymer templates were synthesized using norbornene and 5-norbornene-2, 3-dicarboxylic acid by ring-opening metathesis polymerization. By introducing bismuth salt into these prepared diblock copolymer template, the Bi2O3-based composite nanoclusters were achieved. XRD, FTIR, and TEM were used severally to characterize the Bi2O3 particles, the process of oxide formation, and the size of nanoclusters.
