Acrylic/casein latexes with improved coating performance

Tuesday, 8 November 2016

The production of acrylic/casein nanocomposites constitutes a promising alternative for developing new materials from renewable resources and with an important substitution of petroleum based monomers.

Unfortunately, a low degree of grafting between both components limits their successful application in many fields.

Hybrid film properties were enhanced

This proposal opens the opportunity for synthesizing polymer/casein nanocomposites with controlled degree of grafting by using, in the emulsifier-free emulsion polymerization of acrylic monomers, highly-methacrylated casein with varied degree of functionalization. The benefits of this strategy are assessed by analysing the performance of the obtained hybrid nanocomposites for their application as bio-based waterborne coatings.

The study is published in: Progress in Organic Coatings, Volume 101, December 2016, Pages 587–596
