'Green' Durable Starch-based Resins and Nanocomposites

Detailed Technology Description
A fully 'green' water-based process was developed to crosslink waxy maize starch withBTCA – a low-cost polycarboxylic acid commonly used in the textile industry –resulting in stronger, more durable and stable starches that can substitute forpetroleum-based materials in a broad range of applications.

*Abstract

‘Green’ thermosetresins and composites were fabricated from an abundantly available andsustainable bio-based polymer: starch. A fully 'green' water-based process was developed to crosslink waxy maize starch withBTCA – a low-cost polycarboxylic acid commonly used in the textile industry –resulting in stronger, more durable and stable starches that can substitute forpetroleum-based materials in a broad range of applications. These new starches are also tunable and canbe manipulated as desired by using additives such as nano-clays, nanotubes,plasticizers, and many other fillers. For example, theaddition of micro-fibrillated cellulose (MFC) resulted in nanocomposites withenhanced mechanical properties, which could be used as a resin to fabricate biodegradable,fiber-reinforced hybrid composites.

 

Potential Applications

Petroleum-based materials, e.g. plastics, polymers, resins, composites, etc.

 

Advantages

  • Sustainability, i.e. environmentally-friendly, biodegradable, low-toxicity
  • Low cost materials
  • Small carbon footprint
  • Scalable process
