Summary
Knowledge about crystal structure and chemistry of phyllosilicates are necessary to make proper modification for preparation of nanoparticles, organo-silicates, nanomaterials with optical and antibacterial effects, and clay minerals exfoliated in polymers.
Learning Outcomes of the Course Unit
Classification and characterization of the layered silicates (phyllosilicates).
Modification procedures of phyllosilicates used for the nanosilicates preparation.
Methods applied for the characterization of original and modified materials.
Prediction of procedures and new silicate nanomaterials for their further application.
