Researchers created a new type of paint made from plant-based materials using a core-shell approach.
The team synthesized a bio-based alkyd-acrylic hybrid emulsion using a core-shell approach, where an acrylic shell surrounds a bio-based alkyd core. The alkyd core was made from bio-based sebacic acid through a step-by-step growing polymerization process. The acrylic shell was created through emulsion polymerization in the presence of the alkyd resin.
Abstract
The main objective of this work was to synthesize bio based alkyd-arcylic hybrid emulsion by using core shell approach. Step by step growing polymerization was used for the preparation of the bio-based alkyd resin. Bio-based sebacic acid was used in the synthesis. In the core shell approach; shell part contains acrylic polymer, core part contains bio based alkyd emulsion, which was synthesized by phase inversion. The acrylic shell was synthesized in the presence of the alkyd resin by the emulsion polymerization method.
