Surface Wrinkling on Polydimethylsiloxane Microspheres via Wet Surface Chemical Oxidation
Here we introduce a simple low-cost yet robust method to realize spontaneously wrinkled morphologies on spherical surfaces. It is based on surface chemical oxidation of aqueous-phase-synthesized polydimethylsiloxane (PDMS) microspheres in the mixed H2SO4/HNO3/H2O solution. Consequently, curvature and overstress-sensitive wrinkles including dimples and labyrinth patterns are successfully induced...
متن کاملAnisotropic, hierarchical surface patterns via surface wrinkling of nanopatterned polymer films.
By combining surface wrinkling and nanopatterned polymer films, we create anisotropic, hierarchical surfaces whose larger length-scale (wrinkling wavelength) depends intimately on the geometry and orientation of the smaller length-scale (nanopattern). We systematically vary the pattern pitch, pattern height, and residual layer thickness to ascertain the dependence of the wrinkling wavelength on...
متن کاملSurface Wrinkling in Liquid Crystal Elastomers
Structured surfaces give rise to novel and potentially useful properties such as controllable wettability and structural colour. Here, we demonstrate structured surfaces via reversible surface wrinkling in liquid crystal elastomers (LCEs). A thin polymer film deposited on top of a shape-responsive LCE exhibits a reversible, periodic surface wrinkling pattern in response to temperature changes. ...
متن کاملSubmicron separation of microspheres via travelling surface acoustic waves.
Submicron separation is the segregation of particles having a diameter difference of less than one micrometre. We present an acoustofluidic particle separator with submicron separation resolution to study the continuous, label-free, and contactless separation of polystyrene (PS) particles based on their acoustofluidic parameters such as size, density, compressibility and shape. In this work, th...
