Abstract
An in situ ionic interaction between two additives, one a cationic strength enhancing additive and one an anionic crosslinking additive, is used to improve the mechanical properties of an article formed from a composite material. The composite has a discrete phase bound together with a film of the additives, such as gypsum crystals bound together by a film of substituted starch or cellulose ether.
Claims20
An organic-inorganic composite, comprising an inorganic phase and an organic phase, wherein the organic phase is formed of a strengthening additive ionically crosslinked by a crosslinking additive in situ, wherein the crosslinked strengthening additive forms a polymer network and the ionic interactions between the strengthening additive and the crosslinking additive substantially strengthen the organic-inorganic composite.
A cationic cellulose, comprising a cellulose having one or more the hydroxyl groups substituted by a cationic substituent.
