Building self-supporting all-liquid hierarchical constructs using polysaccharide nanoparticles-stabilized interfaces

Project description

Using nanoparticles to create stable structures within liquids

Crafting advanced multifunctional materials from liquids is difficult owing to their inherent lack of structural order. Funded by the Marie Skłodowska-Curie Actions programme, the INTERLAYER project plans to assemble nanoparticles to stabilise liquid interfaces, enhancing their elasticity and mechanical strength. Current nanoparticle-stabilised multiphase materials suffer from low particle concentration at interfaces, limiting their potential. INTERLAYER introduces a novel processing technique to increase nanoparticle concentration, enabling stable, self-supporting liquid structures. By utilising sustainable polysaccharide nanoparticles from plants, the project will not only boost material properties but also offer an eco-friendly alternative to traditional fossil-based materials.

Objective

Liquids lack the spatial order required for advanced multifunctional materials with spatial resolution. However, self-supporting structured all-liquid multiphase systems would create a new class of biomimetic and reconfigurable materials. This can be achieved by assembling nanoparticles (NPs) at the liquid-liquid interfaces providing enhanced interfacial elasticity and stability. However, NPs-stabilised multiphasic materials currently suffer from low mechanical strength owning to the limited particle concentration that can be achieved at the interface, ultimately limiting the structure-property space. To remove these limitations, INTERLAYER sets out to localise NPs at the interface with much higher concentration via novel advective processing for the first time, enabling non-equilibrium kinetically trapped stabilized states. This will impart enhanced interfacial and bulk mechanical properties, while offering a unique and material-efficient route to create novel self-supporting all-liquid hierarchical constructs. The choice of polysaccharide nanoparticles (PNPs) in INTERLAYER, isolated top-down from plant-based sources, offers a promising platform with adaptability in particle shape, size, and surface chemistry. PNPs are also a sustainable alternative for fossil-based surfactants and inorganic particles, and are gaining increasing attention from industry. INTERLAYER will establish static state diagrams linking PNP physico-chemical properties to the multiphase material structure (Objective 1). Elucidating the physics-chemistry-processing relations will allow the production of novel self-supporting all-liquid hierarchical constructs stabilized by PNPs-laden interfaces (Objective 2). These constructs will then be used to build multiphase materials with more complex structures and advanced functionalities via 3D printing (long-term vision). INTERLAYER will pave the way to the next-generation sustainability-by-design materials, contributing to a more sustainable world.
