Abstract :
[en] Fossil fuels have been the main source of starting materials for the chemical industry over the last century. Especially synthetic polymers rely on this feedstock and are indispensible for mankind’s technological advances and status quo. However, a shift to renewable and sustainable resources is needed, as the end of the fossil fuel era is in sight. Biomass presents one possible alternative to fossil fuels, as it consists of a large pool of different chemicals and is inexhaustible. Cellulose, and the closely related starch and amylose, are available cheaply from plants and have favourable properties, such as high strength, thermal stability and biodegradability. However, such poly(saccharides) have been difficult to use directly as materials because of the lack of thermoplasticity, low solubility and high hydrophilicity. Modifications are thus necessary to be able to exploit their advantageous properties. Recently, our group published the catalytic transesterification of maize starch with different plant oils to obtain fully renewable fatty acid starch esters in a sustainable fashion. Polymeric materials with glass transition temperatures (Tgs), soluble in common organic solvents and an increased hydrophobicity were obtained. Compatibilisation tests of the modified starch and amylose with low-density poly(ethylene) (LDPE) and cellulose are being investigated to obtain composites of commodity plastics with improved mechanical properties.
