Modified bio-based silica to improve the properties of polymeric matrices

One of the greatest challenges today is to move from a non-renewable fossil-based economy to a more sustainable model of economic development. Due to the depletion of natural resources, increasing greenhouse emissions and awareness of the need for sustainable development, the valorization of biomass feedstocks is emerging as an important trend in line with the circular economy concept. In this context, the ReInvent project aims at the valorization of different agroforestry residues for the development of novel bio-nanofillers for insulation in structural products used in buildings and lightweight soft foams for automotive interior components. As part of the project, bio-based silica nanoparticles will be extracted from agro-based biomass and subsequently modified to impart enhanced properties to the final products. The functionalized bio-based silica particles will be incorporated into polymeric matrices to be used to produce new advanced cellular and composite materials with improved hydrophobic, antifungal and flame-retardant properties.
