Starch and cellulose nanocrystals together into thermoplastic starch bionanocomposites
Carbohydrate Polymers, 2015In the present work, thermoplastic maize starch based bionanocomposites were prepared as transparent films, plasticized with 35% of glycerol and reinforced with both waxy starch (WSNC) and cellulose nanocrystals (CNC), previously extracted by acidic hydrolysis. The influence of the nanofiller content was evaluated at 1 wt.%, 2.5 wt.% and 5 wt.% of WSNC.

Effects of hydrophobized starches on thermoplastic starch foams made from potato starch
Carbohydrate Polymers, 2018Single 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

Thermoplastic starch/natural rubber blends
Carbohydrate Polymers, 2003Thermoplastic starch/natural rubber polymer blends were prepared using directly natural latex and cornstarch. The blends were prepared in an intensive batch mixer at 150 °C, with natural rubber content varying from 2.5 to 20%. The blends were characterised by mechanical analysis (stress-strain) and by scanning electron microscopy.

Influence of oxidized starch on the properties of thermoplastic starch
Carbohydrate Polymers, 2013Thermoplastic starch was prepared by adding oxidized starches and glycerol together into starch. The addition of oxidized starch improved the rheological properties and also increased the toughness of thermoplastic starch. Compared with TPS30, the elongation at break increased from 126.8% to 152.5% when 5wt% OS 117% was added.

Potato Starch Based Resilient Thermoplastic Foams
2001Assuming a starch based material can be found able to replace extruded polystyrene foam, a renewable alternative would be available that strongly reduces the amount of foamed plastics in waste streams. In this study it is shown that by the foaming of potato starch based expandable beads such a material can be produced.

Film blowing of thermoplastic starch
Carbohydrate Polymers, 2008Thermoplastic starch materials are often based on a combination of starch, glycerol and water. In the present study, two potato starch grades were employed; a native (natural) grade and an oxidised and hydroxypropylated grade of the native material, in order to produce the thermoplastic material.

Thermoplastic Starch Processing and Characteristics—A Review
Critical Reviews in Food Science and Nutrition, 2014Canola Council of Canada, Winnipeg, Manitoba, Canada The rising costs of nonrenewable feedstocks and environmental concerns with their industrial usage have encouraged the study and development of renewable products, including thermoplastic starch (TPS).

Biodegradation of thermoplastic starch/eggshell powder composites
Carbohydrate Polymers, 2013Thermoplastic starch (TPS) was prepared using compression molding and chicken eggshell was used as a filler. The effect of the eggshell powder (EP) on the properties of TPS was compared with the effect of commercial calcium carbonate (CC). The organic compound on the surface of the eggshell powder acted as a coupling agent that resulted in a strong ...
