Mechanics of interfacial composite materials.
Recent experiments and simulations have demonstrated that particle-covered fluid/fluid interfaces can exist in stable nonspherical shapes as a result of the steric jamming of the interfacially trapped particles. The jamming confers the interface with solidlike properties. We provide an experimental and theoretical characterization of the mechanical properties of these armored objects, with atte...
متن کاملSilane Modified Diopside for Improved Interfacial Adhesion and Bioactivity of Composite Scaffolds.
Diopside (DIOP) was introduced into polyetheretherketone/polyglycolicacid (PEEK/PGA) scaffolds fabricated via selective laser sintering to improve bioactivity. The DIOP surface was then modified using a silane coupling agent, 3-glycidoxypropyltrimethoxysilane (KH570), to reinforce interfacial adhesion. The results showed that the tensile properties and thermal stability of the scaffolds were si...
متن کاملInterfacial propulsion by directional adhesion
The rough integument of water-walking arthropods is well known to be responsible for their water-repellency [1, 2, 3, 4]; however, water-repellent surfaces generally experience reduced traction at an air-water interface [5, 6, 7, 8]. A conundrum then arises as to how such creatures generate significant propulsive forces while retaining their water-repellency. We here demonstrate through a serie...
متن کاملEffect of Interfacial Slippage on Viscoelastic Adhesion
Peeling of a viscoelastic adhesive from a solid substrate poses a wonderful problem of polymer flow. When the adhesive is peeled, it is also stretched in a direction normal to the substrate. The concomitant Poisson contraction creates a pressure gradient and thus induces a shear flow in the adhesive close to the delamination front. Earlier it was pointed out that the strength of viscoelastic ad...
متن کاملInterfacial adhesion of graphene by multiscale models
This article presents a multiscale study on adhesive interactions between graphene and its substrates. First, van der Waals (vdW) interactions between graphene and a SiO2 substrate are studied by fi rst-principle density functional theory (DFT) calculations with dispersion corrections. It is found that the interaction strength is strongly infl uenced by changes of the SiO2 surface structures du...
