一般描述

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.

应用

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。

特点和优势

  • 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。

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

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
