Abstract

Particles derived from lignins and tannic acids as well as nano-polysaccharides are renewable and sustainable answers to some of the demands of the future bio-economy. They have been at the center of our interest in efforts to reveal their remarkable opportunities, especially for the formulation of multi-phase systems, including emulsions and foams. Various options for deployment of related, emerging nano- and micro structures are anticipated considering their morphogenesis, interfacial activity and their ability to network and self-assemble in aqueous suspension, especially applicable to nanocelluloses and nanochitins. The combination with surfactants and surface functionalization expands further the possibilities, for example, in converting emulsions into high order, 3D structures, stimuli-responsive and bioactive materials. In these and other applications, we consider cost drivers and scalability, both of which are quite promising. Our recent research in these areas will be summarized, providing some leading examples of the potential of such fascinating bio-based materials.
