Dr David Fengwei Xie focuses on various biodegradable, biobased, and natural polymers, including their fundamentals, processibility (rheology), blends and (nano)composites for desirable properties and novel applications.

His focus in recent years has been on the mechanistic characterisation of starch polymers and the rheology, processing, and product design of starch-based biomaterials. His goal is to expand the use of starch biopolymers as a substitute for traditional nonrenewable and nonbiodegradable petroleum-based synthetic polymers by solving the processing problems and product performance limitations associated with starch polymers.

Research Interests

  • Biopolymer fundamentals
    - Supramolecular structure of native starch granules - Phase transitions (gelatinisation, melting, dissolution, glass transition) of starch - Chemical and physical modification of biopolymers (starch, chitosan) - Non-derivitising dissolution of biopolymers
  • Biopolymer processing
    - Processing techniques and rheology for biopolymers - Plasticisation and structural evolution of biopolymers during processing - Reactive processing of biopolymers - 'Green' processes for biopolymers
  • Biopolymer-based/derived materials
    - Biopolymer-based blends and (nano)composites - Biopolymer-based/derived materials with novel structures and functionalities - Biopolymer-based/derived materials for high-value applications - Processing-structure-property relationships for biopolymer-based materials
