Technical Innovation
Development of an advanced material matrix infused with functionalized nano‑additives (e.g., graphene oxide, nano‑silica) to achieve >50 % improvement in tensile and flexural strength over conventional binders.Research Approach
Formulation: Surface‑functionalize nano‑additives with silane or phosphate coupling agents for chemical bonding to aluminosilicate network.
Processing: Disperse nano‑additives via ultrasonication into alkali‑activated metakaolin precursor. Cast and cure under controlled humidity and temperature.
Characterization: Use nanoindentation, 3‑point bend, and fracture toughness testing; analyze microstructure by SEM/TEM and X‑ray tomography.
Potential Patent Claims
A method for producing a nano‑reinforced geopolymer composite comprising steps of functionalizing and dispersing nano‑additives into an alkali‑activated aluminosilicate matrix.
The composite material exhibiting specific ranges of improved tensile strength (e.g., 20–30 MPa) and fracture toughness (>2 MPa·m^0.5).
Use of such composite in high‑performance structural panels, load‑bearing elements, or 3D‑printed construction components.
