Abstract

Nanocellulose is a new class of sustainable nanomaterials that are typically obtained by carefully deconstructing the most-abundant lignocellulosic biomass into nanoscale level. Due to their excellent specific mechanical properties, high surface with tunable functionalities, and better optical properties at nanoscale level, they are explored for several industrial, value-added applications. The presentation will be demonstrate the use of nanocellulose as a functional additive in thermoplastic polyurethanes (TPU)1, rigid polyurethane foam (RPUF)2, cementitous and bituminous materials for enhancing the thermal insulation, rheological and mechanical properties. For example, incorporation of only 0.4 wt.% of rod-like cotton nanocellulose in a polyether based RPUF has improved the thermal insulation performance by 5% and the compressive mechanical properties  up to 9 -11 %.2-3 Similarly, the incorporation of 0.5 wt. % of spinifex nanocellulose in to TPU has improved tensile strength 43 %.  Further, the discussion will be made on the sustainable and low-energy consuming deconstruction methods for the production of nanocellulose with different morphologies a common cellulose sources cotton, wood and a unique grass source called ‘spinifex’ endemic to Australian continent.4-5 It will also include the organic-solvent free methods for incorporating cellulose in to polymers.
