Gel Template Synthesis

High-temperature superconductor nanowires have been obtained in a similar way as the alginate-assisted synthesis, the chitosan acting as gel-template (Schnepp et al. 2008). The polymer ability to capture and bind metal ions and thus to provide preferred nucleation and crystal growth sites allows the control of the high-temperature superconductor YBa2Cu4O8 particles morphology and prevent the particles sintering during the heating treatment (Hall 2006).
