Cellulose is the most abundant polymer and a very important renewable resource. Since cellulose cannot be shaped by melting, a major route for its use for novel materials, new chemical compounds and renewable energy must go via the solution state. Investigations during several decades have led to the identification of several solvents of notably different character. The mechanisms of dissolutio...

Single-use plastics are a major source of pollution and biodegradable polymers could be the best substitute, as they possess similar barrier functional properties. Aiming at improving properties providing antioxidant bioactivity, PLA (PolyLactic Acid) films were coated with crosslinked suspension plasticized gelatin incorporating phenolic compounds. The coating process induced weak modification...

Plasticizers are commonly used plastic additives. Deep understanding of their effect on the migration other substances is essential, especially for food contact materials. The kinetics four stabilizer-type additives from polypropylene (PP) and polylactic acid (PLA) with different tributyl acetyl citrate plasticizer content were investigated. results confirm that presence in plastics enhances sw...

The quartz crystal microbalance (QCM) is used as a non-destructive and efficient characterization tool for thin thermoplastic starch (TPS) films. Thin TPS films (1-2 ?m) were prepared with 30% (w/w starch) plasticizers using either glycerol or an ionic liquid, 1-ethyl-3-methylimidiazolium acetate ([emim+][Ac?]), the plasticizer. differences in mechanical properties environmental effects on plas...

The influence of the strain rate on plasticization effect (PE) ultrafine-grained (UFG) Al-1.47Cu-0.34Zr (wt%) alloy structured by high pressure torsion. A significant increase in plasticity (more than 2 times) while maintaining a level strength (ultimate tensile ~465 MPa) UFG was achieved as result additional deformation-heat treatment (DHT), consisting low-temperature annealing and small defor...
