Interpretive Summary:

Technical Abstract: This invention describes the creation of a unique matrix produced by compounding gypsum (CaSO4.H2O -also known as “Plaster of Paris”) and starch. Created matrix is a massive three dimensional structures containing pores and tunnels of macro, micro and nano size. Such matrices are ideal for encapsulation of chemicals, biological agents, enzymes, active microbes, and could serve as filtration aid for liquids and organic solvents. Gypsum is currently used in construction/building materials such as dry-walls and sheet rocks, etc. In the presence of starch, pores and tunnels in the gypsum will decrease the overall density of the matrix and would greatly enhance its insulation and sound barrier properties as well. Developing novel biobased products and finding new and high-end use of commodities grown in abundance will improve the rural economy, directly benefiting American Farmers. Furthermore, adding new and useful functionalities in the existing building materials would equally benefit American industry that relies on gypsum products as well as consumer’ world-wide.
