Thermally triggerable, anchoring block copolymers for use in aqueous inkjet printing

This publication is dedicated to Prof. Brigitte Voit on the occasion of her 60th birthdayThe contamination of wastewater by microplastic particles (MPs) is an unresolved environmental problem. In order to resolve this problem, a concept is developed for the microbial remediation of MPs. To realize this concept, degradable block copolymers are required, which adhere on MP surfaces and contain segments of carbohydrate moieties (here galactose) for the attraction of degrading microbes and accelerated biofilm formation. Therefore, in this study, a versatile synthesis route for amphiphilic carbohydrate block copolymers from poly(d,l-lactic acid) (PLA) and galactose moieties is presented. The properties of the block copolymers are investigated by thermal analysis, as well as regarding their colloidal properties, their adhesion behavior on MP surfaces, and their potential for support of microbial growth (using Lacticaseibacillus zeae).

Thermally triggerable, anchoring block copolymers for use in aqueous inkjet printing

Abstract: Towards the goal of shifting from toxic organic solvents to aqueous-based formulations in commercial inkjet printing, a series of well-defined amphiphilic block copolymers have been synthesized via RAFT polymerization.
