Seaweed-derived polymeric materials for multiapplications including marine algal cultivation

This study described the preparation of phycocolloids based polymeric materials for multiapplications including seaweed cultivation in open sea water conditions via grafting reaction of phycocolloids with vinyl acetate (VAc). Best materials were obtained with high gel strength G. dura agar and the composite polymeric material showed good extrusion characteristic in softened state, high mechanical strength, and low moisture sensitivity. The material could be degraded by burying in the soil making it advantageous both from the perspective of utilizing a marine bioresource as raw materials for preparation of polymeric materials having the desired property of required stability under conditions of use.
