The recent journal article ‘Plasma-assisted surface engineering for value added in starch bioplastics: A study on enhanced surface properties and natural dye’ by Bidhari Pidhatika et al. analyzes how starch-based bioplastics can be coloured using natural dyes. Thus, this study aims to support the search for sustainable alternatives to petroleum-based plastics.

This study demonstrates how plasma treatments and an additional binder can enhance stable colouration with natural dyes on starch bioplastic surfaces. Specifically, the researchers examined  two natural dyes – telang and curcumin – and their performance on bioplastics made from cassava. They found that curcumin adhered well to the bioplastic surface, even without plasma treatment and additional binder. Telang, on the other hand, required plasma treatment and an additional binder to adhere strongly to the surface.

In this paper, the ZPA 20 Zeta Potential Analyzer from DataPhysics Instruments was used to obtain important data on the surface charge of the samples.
