Abstract
Disclosed herein are additives made by modifying starch with different types of polyhedral oligomeric silsesquioxane (POSS). The starch-POSS additives can provide advantageous properties to polymeric materials.
Claims50
A starch-POSS additive comprising:
- a starch that is at least 30% by weight amylose, and
- a POSS coupled to the starch.
A method of making a starch-POSS material, the method comprising
- combining a starch and a POSS comprising at least a linking group in the presence of a catalyst and a solvent to form a starch-POSS material, and
- isolating the starch-POSS material,
- wherein the starch is at least 30% by weight amylose.
