In this work, an onion-like carbon (OLC) nanoparticle coating with a micron-sized thickness was fabricated via aerosol deposition (AD). During the room temperature impact consolidation (RTIC), the OLC nanoparticles (5–10 nm) experienced remarkable deformation along both the perpendicular and parallel directions to the coating-substrate interface. Particle deformation, mechanical interlocking, and van der Waals forces between the OLC particles were revealed as the major regimes for coating formation. The aerosol deposition technique might open new avenues for fabricating carbonaceous nanostructures for various functional applications.

通过气溶胶沉积有效制备洋葱状碳纳米颗粒的涂层

在这项工作中，通过气溶胶沉积（AD）制备了微米级厚度的洋葱状碳（OLC）纳米颗粒涂层。在室温冲击固结（RTIC）过程中，OLC纳米颗粒（5-10 nm）沿与涂层-基材界面的垂直和平行方向均发生了明显的变形。揭示了OLC颗粒之间的颗粒变形，机械互锁和范德华力是形成涂层的主要机制。气溶胶沉积技术可能为各种功能应用领域的碳纳米结构的制造开辟新途径。
