Novel biobased micro- and nanomaterials in porous foam formed structures
Abstract
This work applies the knowledge on multi-scalelignocellulosic fibres and proteins to create novelporous fibre structures using a foam forming technology.In particular, the aim is to enable new materialproperties by combining multi-scale wood and agro fibres,fines, cellulose nanofibrils and surface active proteinswhen using foam-assisted forming process. The designdriven approach contributes to the selection of rawmaterials and tailoring of desired micro and macrostructures through the processes. The future applicationsinclude e.g. cushioning elements in packaging andacoustic materials in indoor construction. Thecompression strength is one of the most criticalmechanical properties in both applications areas.In our study, lignin-rich fines made of spruce wood andcellulose nanofibrils improved the compression strengthof foam formed structures made with SDS and PVA asfoaming agents. The used cellulose nanofibrils wereTEMPO-oxidised (TCNF) and native grades (CNF). In thiswork, the retention of CNF fibrils in foamed porousstructures was studied using x-ray tomography images andelementary analysis from iron-cobalt labelled mass andwater samples. The surface active proteins wereinvestigated as a mean to strengthen the lamella of airbubbles for stabilizing the aqueous fibre foams made withSDS. The produced stronger wet foamed structures canreduce drying time significantly allowing vacuum-baseddewatering. Overall, wide-range selection of novelbio-based micro -and nanomaterials significantly improvedthe important process and product properties of highlyporous foamed structures.
