Dr Pratheep Kumar Annamalai
Dr. Pratheep Annamalai is a polymer and nanomaterials scientist with a keen interest in engineering materials for sustainable living.
He has extensive expertise in both translational and fundamental research using nanotechnological tools towards sustainability. As a senior research fellow at the AIBN, he is interested in valorisation of native (spinifex grass) and alternative feedstock into reactive, nanoscale building blocks for improving the performance and utility of materials for infrastructure, agriculture, and food. Thematically, his research focuses on:
- Bioproducts (from lignin and cellulose)
- Nano-enabled construction materials (cement, gypsum, and bitumen)
- Engineered polymers (elastomers, carbon fibre),and
- Insulation materials (rigid polyurethane foam, lignocellulose)
Collaborations and Industry Engagement
- Bulugudu Limited (Formerly known as Dugalunji Aboriginal Corporation) (2016 -)
- Spantech Building Innovation (2021)
- Department of Transports and Main Roads (2016 - 2019)
- Australian Road Research Board (2016 - 2019)
- Dow Chemicals, MI, USA through UQ-Dow Centre (2014-2015)
- TenasiTech Pty Ltd (2012-2014)
Under the ARC sponsored project, the collaboration with Deakin University (IFM-Carbon Nexus) involves developing spinifex nanocellulose based carbon-fibre presursors. With ANSTO, the collaboration involves studying the understanding the native spinifex cellulose fibril structure through small-angle scattering techniques.
Within UQ, the collaboration involved with the School Chemical Engineering and School of Civil Engineering is on several engineered polymer and nanomaterials for industrial applications.
