NCC AS A FUNCTIONAL SCAFFOLD FOR AMINE-CURED EPOXY NANOCOMPOSITE MATERIALS OF TUNABLE PROPERTIES |
摘要 |
The disclosure relates to a novel process for functionalizing NCC, a method for producing amine-cured epoxy-based nanocomposites through the use of said functionalized NCC, and nanocomposites thereof. The process for functionalizating NCC comprises providing a mixture of NCC and one or more monomers. The mixture is suitable for free radical polymerization and the monomer is cross-linkable with epoxy and is aqueous soluble. The polymerization takes place in the presence of a free radical initiator and oxygen is purged from the mixture and the initiator solution. The epoxy-based nanocomposite is produced by mixing the funtionalized NCC with an amine-curable epoxy resin and a hardener, in a solvent, and allowing the mixture to cure. |

1. A process for functionalizing NCC comprising:
(i) providing a mixture of NCC and one or more monomers, wherein said mixture is suitable for free radical polymerization and said monomer is cross-linkable with epoxy and is aqueous soluble; (ii) providing a free radical initiator or a solution thereof; (iii) purging oxygen from the mixture of (i) and the solution of (ii); (iv) mixing (i) and (ii) after step (iii) to allow polymerization; and (v) isolating said functionalized NCC. |
