Water-based polyamide-imide (WPAI) resin has received extensive attention due to its greenness, safety, and favorable comprehensive properties. However, its low degree of molecular chain crosslinking results in poor heat resistance and mechanical strength, which seriously restricts its application as a matrix material for composite membranes. In this work, WPAI composite membranes were fabricated via the incorporation of artificially cultured diatom frustules (DFs), a biomass-based silicon dioxide material with a 3D penetration network structure. The prepared DFs@WPAI nanocomposite membranes are a novel green water-based material, which notably minimizes the utilization of toxic organic solvents. Moreover, the DFs-5@WPAI nanocomposite membrane after systematic optimization of structure and composition exhibits superior thermal stability (maximum servicing temperature of 514C) and mechanical strength (especially hardness of 0.39 GPa), which is comparable to those of the organic solvent-based composite membranes. The strengthening mechanisms of the DFs@WPAI nanocomposite membranes are attributed to the dual effects of physical riveting and in-situ chemical bonding between the DFs and the WPAI resin.
