Biocomposites of thermoplastic starch with surfactant

Carbohydrate Polymers, 2008
Abstract Thermoplastic starch films were prepared by a casting technique. Microfibrillated fibers from husks of corncobs were added as reinforcing agents and glyceryl monostearate (GMS) as surfactant. The films were characterized using X-ray diffraction studies, thermal and mechanical analysis and water uptake experiments.

Formamide as the plasticizer for thermoplastic starch

Journal of Applied Polymer Science, 2004
AbstractAs a novel plasticizer, formamide was tested in thermoplastic starch (TPS), in which native cornstarch granules were proved to transfer to a continuous phase by scanning electron microscope (SEM) and the hydrogen bond interaction between plasticizer and starch was proved by Fourier transform infrared (FTIR) spectroscopy. Mechanical tests showed

Gelatinization of Thermoplastic Starch Polymers [PDF]

This project was carried out in conjunction with Plantic Technologies, which has developed and now manufactures a new low cost, starch-based biodegradable plastic. The aim of this project was to determine the effect of varying the number of extrusion stages on the degree of gelatinization of the extrudate to be used in injection moulded, starch-based ...

The processing of starch as a thermoplastic

Macromolecular Symposia, 2003
AbstractThe thermoplastics processing of native starch in the presence of water is a recent development with very wide possible applications. Eventually, oil‐based polymer materials have to be replaced in many applications by sustainable, inexpensive, natural materials from renewable resources.

Thermoreversible crosslinked thermoplastic starch

Polymer International, 2015
AbstractA novel furan‐modified thermoreversible crosslinked thermoplastic starch was synthesized. The crosslinking mechanism was based on a thermoreversible furan/maleimide adduct formed by the Diels − Alder reaction. Thermoplastic starch (TPS) was first modified by forming a urethane linkage between the product of the reaction of furfuryl alcohol with

Thermoplastic Starch Polymer Blends and Nanocomposites

2012
This paper reviews the development of bio-based thermoplastic starch polymer blends and nanocomposites at the University of Queensland. Starch-based thermoplastics are relatively cheap and more importantly manufactured using a renewable biomaterial. However traditionally most thermoplastic starch polymers suffer from low water resistance and loss of ...

Effects of hydrophobized starches on thermoplastic starch foams made from potato starch

Carbohydrate Polymers, 2018
Single use food packaging made from expanded polystyrene (EPS) is generally discarded after use and, since it is a difficult material to recycle, generates a large amount of waste. The EPS can be replaced by thermoplastic starch (TPS) foams, which are made from renewable sources and are biodegradable. However, TPS foams are hydrophilic and absorb large

Understanding the Processing of Thermoplastic Starch

Macromolecular Symposia, 2006
AbstractThe thermoplastics processing of native starch in the presence of water is a recent development with very wide possible applications. Eventually, oil‐based polymer materials have to be replaced in many applications by sustainable, inexpensive, natural materials from renewable resources. The present contribution focuses on the injection moulding

Chemical Modification of Thermoplastic Starch

2015
Thermoplastic starch (TPS) has been used since the 1990s as a thermoplastic material produced from native starch by its processing in the presence of a plasticizer, usually glycerol. The great advantage of TPS is the possibility of using conventional equipment from the plastics industry, either for its production or transformation into an end product ...
