Oxyde d′aluminium

Aluminum oxide nanoparticles (AlNPs) are porous nanomaterials with corundum-like structures. They possess high surface area, mechanical strength, and good optical properties. In addition, they have excellent chemical stability in harsh conditions such as abrasive environments and high temperatures. The ease of surface modification and bioinertess make them suitable for biomedical applications. These nanomaterials can be prepared by a cost-effective and simple protocol.

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Aluminum oxide serves as a multifunctional additive or coating in lithium-ion batteries, helping stabilize electrode–electrolyte interfaces, suppress side reactions, improve thermal stability, and extend cycle life. By enabling safer, longer-lasting cells, it reduces material waste and energy use across the battery lifecycle. Click here for more information.

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.
