Technical Abstract: Most industrially promising nanocomposites have been derived from clay-polymer hybrid materials. This reports discusses the alternative of using cellulose microfibrils as the reinforcing matrix within polymer nanocomposites. Cellulose microfibrils are single-crystal, needle-like fragments isolated from cellulose-rich pulps, ranging in diameter from 3-20nm in length from 50-500nm. At loadings of 2-10%, these particles improve tensile and bending modulii by 10-20 fold, and improve polymer film flexibility. As will be discussed, surface chemistry, such as reaction with malic anhydride, enhances polymer-cellulose miscibility.
