Abstract: Nanocellulose is a class of materials derived from trees, plants and many other organisms that are prismatic to fibular in habit depending upon the extraction method and have promising mechanical, physical, electrical, and optical properties.1 Nanocellulose is used in these organisms as the primary component of their reinforcing phases. In their pure crystalline form, they are single crystals of cellulose referred to as cellulose nanocrystals (CNCs). Those extracted from trees are 3-5 nm in width and thickness, and 100’s nm in length. CNCs have modulus and tensile strength on par or better than aramid fiber, low den-sity and thermal expansion, and have refractive index simi-lar to most polymers.1 Thus, they are potentially ideal for use in polymer matrix composites. A key challenge in this regard is their hydrophilic surfaces that must be converted for compatibility and curtailed hygroscopicity. Herein we report the conversion of CNC surfaces and the properties of the resultant epoxy – nanocellulose elastomers.
