Application

铝纳米颗粒可用于制备：
  • 水基纳米流体，这种纳米流体被用于发动机冷却、热交换和核冷却系统。氧化石墨烯、铝纳米流体，其中添加铝纳米颗粒改善了氧化石墨烯的物理结构，降低复合材料的粘度。
  • 聚硅氧烷-氧化铝复合材料，可用于作为发光二极管的弹性导热垫片。
它还可被用作添加剂。改善聚氯乙烯的机械性能。Al2O3 纳米颗粒在聚合物基体中作为惰性固相，限制了高分子链的移动。因此提升了玻璃化温度，并降低了弹性模量。

Features and Benefits

  • 在严苛的非生物环境中性质稳定。
  • 它们可以通过已有的合成方法轻松制备。
  • 它表面积很大，可以与化学和生物分子结合
  • 它们表面改性方案非常直观。
  • 它们很容易与生物界面相互作用。

General description

氧化铝纳米颗粒（AINPs）是多孔，刚玉结构的纳米材料。它们拥有高表面积、机械强度和良好的光学性能。此外，它们在恶劣条件下，如磨损环境和高温下，具有优异的化学稳定性。易于表面改性和生物惰性使它们适用于生物医学应用。这些纳米材料可以通过经济、简单的方法制备。
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.

Recent studies revealed higher polymer flooding performance upon adding metal oxide nanoparticles (NPs) to acrylamide-based polymers during heavy oil recovery. The current study considers the effect of TiO₂, Al₂O₃, in-situ prepared Fe(OH)₃ and surface-modified SiO₂ NPs on the performance of

Solution dispersions of two-dimensional (2D) black phosphorus (BP)--often referred to as phosphorene--are achieved by solvent exfoliation. These pristine, electronic-grade BP dispersions are produced with anhydrous organic solvents in a sealed-tip ultrasonication system, which circumvents BP degradation that would otherwise occur

We demonstrated a promising route for enhancing temperature sensitivity, improving saturation voltage, and reducing power consumption of the MOS(p) tunneling temperature sensors by introducing ultrathin Al2O3 into the dielectric stacks. Detailed illustrations of the working mechanism and device concept are

Glass formation in the CaO-Al2O3 system represents an important phenomenon because it does not contain typical network-forming cations. We have produced structural models of CaO-Al2O3 glasses using combined density functional theory-reverse Monte Carlo simulations and obtained structures that reproduce experiments
