Abstract
Methods for isolating cellulose nanocrystals (CNCs) from the plant Miscanthus Giganteus (MxG). Impressive yields are obtained through a combination of processing steps including base hydrolysis, bleaching and acid hydrolysis. MxG-CNCs are produced having high aspect ratios, are biorenewable and can be used for a wide range of applications such as nanofillers in composites. MxG-CNC-containing composites are also disclosed.
Claims4
A composite composition, comprising:
- a matrix material;
- and cellulose nanocrystals from Miscanthus Giganteus,
- wherein the matrix material comprises one or more polymers or copolymers,
- wherein the polymers or copolymers comprise an alkylene oxide (co)polymer, a vinyl aromatic (co)polymer, a polyolefin (co)polymer, a diene (co)polymer, a polyacrylate (co)polymer, poly(vinyl acetate), poly(vinyl alcohol), a polyamide, a polyurethane, a polyester, or a combination thereof, and
- wherein the cellulose nanocrystals from Miscanthus Giganteus are present in an amount of 1 to 20 parts based on 100 parts by weight of the matrix material.
