Making Polymers Colored and Stiffer by Dyed Regenerated Cellulose Employing Pickering Emulsions

We describe how uniformly colored PMMA-cellulose composites with high transparency in the visible range can be obtained. We provide detailed characterization of the resulting composites. Thermogravimetric analysis shows an increase of onset of degradation temperature, thus indicates improved thermal stability. Also the mechanical properties become improved, as indicated by flexural strength enhancement. The Pickering emulsion-based procedure is simple and cost effective, and could be easily adopted to prepare other polymer-nanocomposite systems.Graphical abstractThis work presents the preparation of well-defined composites of polymethyl methacrylate and dyed regenerated cellulose via a Pickering emulsion approach. The Pickering emulsion-based composition procedure is simple and cost effectively, and could be easily adopted to the preparation of similar polymer-nanocomposites.
