20110257283POLYMERIC COMPLEX SUPPORTER FOR CONTROLLING OXYGEN-RELEASING SUBSTANCES AND METHOD FOR MANUFACTURING THE SAME - A polymeric complex supporter for controlling oxygen-released compounds (PCS-ORCs) and a method for manufacturing the same is disclosed. PCS possesses a porous surface and internal coralloid-like channel structure that can accommodate ORCs with a high ratio (up to 92 wt %) to polymers. In applications, the PCS-ORCs can be shaped as various types and be coupled with other solids that could be used as delivery tools. As PCS-ORCs is delivered into a water-containing environment, water molecules can diffuse into the internal channels through the surface pores and then react with ORCs. Due to the tunable structure properties of PCS, the produced oxygen can be release out through the surface pores for one to six months long. In comparison with powder-type ORCs, PCS-ORCs can exhibit better application potentials in terms of time-release technology, oxygen delivery and environmental responsibility.10-20-2011
