Application
Aluminum nanoparticles can be used to prepare:

• Water-based nanofluids, which are used in engine cooling, heat exchangers, and nuclear cooling system. In graphene oxide/alumina nanofluid, the addition of aluminum nanoparticles improves the physical structure of graphene oxide and reduces the viscosity of the composite.
• Polysiloxane-aluminum oxide composites, applicable as an elastomeric thermal pad for light-emitting diodes.

It can also be used as an additive to improve the mechanical properties of polyvinyl chloride. The Al2O3 nanoparticles act as a solid inert phase in the polymer matrix and restrict the mobility of chains. As a result glass transition temperature increases and elastic modulus decreases.

Features and Benefits

• Stable in a harsh non-biological environment.
• They can be easily prepared through established synthesis methods.
• A vast surface area allows conjugation with chemical and biological molecules.
• Their surface modification protocols are straightforward.
• They can easily interact with biological interfaces.
