• Resumen

  • We report two selective morphologies of CaCO3 crystals using poly(potassium 2-acrylamido-2-methylpropanesulfonate) [poly(KAMPS)] as template through gas diffusion method. The presence of anionic sulphonte groups on poly(KAMPS) determined the kinetic crystallization and was fundamental for stabilizing oriented triangle and tubular shape of calcite. The modified CaCO3 were followed by SEM and XRD techniques. Inorganic architectures with hierarchically complex shape and optimized properties have great potential as agents in optical, electronic, magnetic and biomedical applications.
