Reinforcement of Thermoplastic Corn Starch with Crosslinked Starch/Chitosan Microparticles

Tailoring barrier properties of thermoplastic corn starch-based films (TPCS) by means of a multilayer design.

This work compares the effect of adding different biopolyester electrospun coatings made of polycaprolactone (PCL), polylactic acid (PLA) and polyhydroxybutyrate (PHB) on oxygen and water vapour barrier properties of a thermoplastic corn starch (TPCS) film. The morphology of the developed multilayer structures was also examined by Scanning Electron Microscopy (SEM). Results showed a positive li...

Green Composites Comprising Thermoplastic Corn Starch and Various Cellulose-Based Fillers

Starch microparticles (SM) were prepared by delivering ethanol as the precipitant into a starch paste solution dropwise. Chemically modified starch microparticles (CSM) were fabricated by a reaction with malic acid using the dry-preparation technique. Composites were prepared using CSM and various cellulose materials as fillers within glycerol plasticized– corn starch matrix through the casting...

Retrogradation and Antiplasticization of Thermoplastic Starch

Petrochemical-based plastics are widely used in modern society due to their high effective mechanical and barrier properties (Farris et al., 2009; Siracusa et al., 2008). However, petrochemical-based plastics have become an environmental concern as they are not biodegradable or recyclable. Replacing the petrochemical-based polymers with biopolymers which are renewable has become an attractive i...

Crosslinking of oxidized thermoplastic starch films

Reusable biocatalytic crosslinked microparticles self-assembled from enzyme-nanoparticle complexes.

Emulsions stabilized by enzyme-nanoparticle (NP) complexes were used to fabricate robust biocatalytic scaffolds after core solidification via crosslinking. These biocatalysts feature ease of formation, high retention of enzymatic activity and reusability.
