The present invention discloses a cross-linked nanoporous saccharide-based material comprising saccharides as building blocks, also referred as nanoporous Nanosponge materials. The reaction of saccharides with cross-linkers at different saccharides to cross-linker ratios in one-pot shall allow formation of nanoporous Nanosponge material. This method further allows introduction of new functional groups on this material by the use of suitable cross-linkers and surface grafting agents, and these functional groups shall be able to provide different interaction forces with water, volatile organic vapors (VOCs) and metal ions. Along with larger inner surface area owing to the presence of nanopores or nanocavities in comparison to porous materials, saccharide-based nanoporous Nanosponge materials shall find broad applications in thermal insulation, water retention, hydrophobic finishes, odor removal properties, and metal ions exchange or absorption from water or soil. The nanoporous Nanosponge materials shall be eco-friendly, biodegradable, and allowing recycle or reuse of spent materials. |
