摘要： The present invention relates to biodegradable hydrophobic composite materials and a process for the preparation of said hydrophobic biodegradable materials from the seaweed polysaccharides through grafting reaction with vinylated monomers e.g. vinyl acetate. The said composites can be used as a substitute for synthetic ropes for varied applications including seaweed cultivation in the open sea. The results of cultivation experiments showed that ropes are suitable for cultivation of seaweeds in the sea environment, and exhibit higher biomass yield as compared to synthetic ropes. The prepared composites are very flexible and can be used for making handles for carry bags and for the preparation of biodegradable designs, bowls, pots, jars, gift items, stud caps and bracelets.

摘要： The present invention relates to a superhydrophilic biodegradable cross linked foam membrane and a process for preparation of said foam membrane from a seaweed polysaccharides by blending with amino biopolymers/amino acids/proteins/amino compounds followed by crosslinking with a naturally occurring cross linker, genipin. The foam membrane can be used as a substitute for synthetic membrane for varied applications including membrane separation for oil-water emulsions, oil-water mixtures and other aqueous-organic mixtures under ambient conditions. These foam membranes can be recycled and reused more than three times without considerable decrease in flux rate and stability. The separation methodology of the mixtures using the foam membrane of the present invention is gravity-driven and therefore, simple and energy-efficient.
