What is it about?
This study is aimed to use biologically renewable cellulose nanocrystals (CNC) as a reinforcing agent to enhance the properties of polyurethane foams (PUF) based on solely palm-polyol.

Why is it important?
The preliminary results showed that the effect of CNC on the mechanical properties afforded a significant improvement on the compressive strength and modulus without affecting much their tensile strength. The results on thermal stability and thermal transitions were found unchanged whereas the storage modulus revealed substantial improvement with the presence of CNC with almost twofold from 0.7 MPa to 1.3 MPa (∼86 %).
Perspectives
The increasing awareness of the environment and the economy of petroleum resources has driven the development of alternative processes and raw materials based on sustainable and renewable biomaterials with excellent properties.
