Abstract

This disclosure provides a foam comprising at least one structuring component selected from lignin, cellulose fibres (CF), cellulose microfibrils (CMF), and cellulose nanofibrils (CNF), bio-based polymer, gelling agent, and closed pores comprising gas, wherein at least some of the bio-based polymers are present in non-covalent complexes with the gelling agent, providing a network structure in the foam. There is also provided a manufacturing method comprising mixing water, bio-based polymer, foaming agent, gelling compounds, and at least one such structuring component, introducing gas and subjecting the gelling compound to stimuli releasing gelling agents from the gelling compound. The foam may be used in a fish guide.
