Engineered Switchable‐Wettability Surfaces for Multi‐Path Directional Transportation of Droplets and Subaqueous Bubbles

Advanced Materials, Год журнала: 2022, Номер 35(9)

Опубликована: Ноя. 25, 2022

Conventional engineered surfaces for fluid manipulation are hindered by the set wettability, and thus they can only achieve spontaneous transport of single-phase fluid, namely liquid or gas. Moreover, systems that robust to path defects have yet be fully explored. Here, unprecedentedly, a universal wettability switching strategy is developed achieving programmable directional both droplets subaqueous bubbles on dumbbell-patterned functional surface (DPFS), featuring in strong robustness, high efficiency, effective cost. By tuning superwettability DPFS through octadecyltrichlorosilane treatment ultraviolet-C selective irradiation, alternate between The material's switchable regulates directed dynamics within confined pattern, which sustaining propelling relies energy difference starting terminal sites. This enables construction multiple channels, works synergistically with ultralow-volume-loss impart fluidic system robustness against defects. Underlying completion complex microfluidics tasks, spatially-selective cooling devices gas microreactors successfully demonstrated. energy-consumption-free opens new avenue on-chip manipulation, promoting innovative applications requiring rational control two-phase transport.

Design of a self-cleanable multilevel anticounterfeiting interface through covalent chemical modulation

Materials Horizons, Год журнала: 2023, Номер 10(6), С. 2204 - 2214

Опубликована: Янв. 1, 2023

Counterfeit products have posed a significant threat to consumers safety and the global economy. To address this issue, extensive studies been exploring use of coatings with unclonable, microscale features for authentication purposes. However, ease readout, stability these against water, deposited dust, wear, which are required practical use, remain challenging. Here we report novel class chemically functionalizable combination physically unclonable porous topography distinct physiochemical properties (e.g., fluorescence, water wettability, adhesion) obtained through orthogonal chemical modifications (i.e., 1,4-conjugate addition reaction Schiff-base at ambient conditions). Unprecedentedly, self-cleanable coating is introduced develop multilevel anticounterfeiting interface. We demonstrate that fluorescent can be verified using deep learning. More importantly, spatially selective read naked eye via underwater exposure UV light illumination. Overall, results reported in work provide facile basis designing functional surfaces capable independent decryption authenticity.

Abstract Bio-inspired surfaces with wettability patterns display a unique ability for liquid manipulations. Sacrificing anti-wetting property confining liquids irrespective of their surface tension (γ LV ), remains widely accepted basis developing patterns. In contrast, we introduce ‘liquid-specific’ pattern through selectively sacrificing the slippery against only low γ (<30 mN m −1 ) liquids.

Abstract Micro and nanopatterned surfaces hold potential for various applications, such as wettability control, antibiofouling, optical components. However, conventional patterning processes are characterized by complexity, high costs, environmental burdens because of the use resists. Therefore, this paper proposes facile ultrafast electrochemical imprinting employing a polymer electrolyte membrane (PEM) stamp achieving micro nanoscale on Si surfaces. The solid‐state process efficiently generates oxide hydrated (Si–OH) patterns within several seconds at room temperature in dry ambient environment. formed pattern can be employed an etching mask to prepare diffraction gratings with diverse high‐resolution (≈100 nm) utilizing PEM stamp. resulting surface exhibits instantaneous structural coloration upon exposure humid air, attributable formation water microdroplet array pattern. is successfully applied dynamic grating letter encryption. proposed oxidation scheme based stamp, which eliminates need liquid resist, represents simple time cost few seconds, low processing costs impact.
