Amsterdam researchers have made a breakthrough in the production of biobased polyesters, which could pave the way for commercial bioplastics

 E-Mail IMAGE: The UV-induced deformation of the polycinnamate was analyzed by time-resolved IR spectroscopy, and it was confirmed that photoexpansion occurred based on the trans-to-cis isomerization of main chain cinnamate units.... view more  Credit: Image courtesy: Tatsuo Kaneko and Kenji Takada from Japan Advanced Institute of Science and Technology. A phenomenon of "photoexpansion" in hard plastic films with a high glass transition temperature in the dry state was established, which was essentially different from very soft actuators, such as elastomers or gels. The photoexpandi...

Producing Biobased Polyesters with Tunable Properties Written by AZoMMar 3 2021 As far as green chemistry is concerned, identifying novel and lasting solutions to the material needs is one of the main targets.

The countless plastics used by people in their everyday life, right from mattresses to food and cars, are mainly made from oil-based monomers that form the building blocks of polymers. Determining bio-based monomers for polymer synthesis is an appealing way to realize more lasting solutions in the area of materials de...
