“…Interest in micro-and nanoparticles has generally been increasing, particularly in polymer particles with enhanced surface roughness and structure, to meet applicationspecific demands such as controlled drug delivery [1,2], super-hydrophobic [3] and icephobic [4,5] surfaces, attachment of cells [6], and adhesion of metal nanoparticles [7,8]. For these purposes, the particle surface can be modified by introducing wrinkles and corrugations [1,3,6,[9][10][11][12][13][14] as well as controlled or self-assembly of particles [15][16][17] into aggregates.…”

Microfluidic techniques allow for the tailored construction of specific microparticles, which are becoming increasingly interesting and relevant. Here, using a microfluidic hole-plate-device and thermal-initiated free radical polymerization, submicrometer polymer particles with a highly textured surface were synthesized. Two types of monomers were applied: (1) methylmethacrylate (MMA) combined with crosslinkers and (2) divinylbenzene (DVB). Surface texture and morphology can be influenced by a series of parameters such as the monomer–crosslinker–solvent composition, surfactants, and additives. Generally, the most structured surfaces with the simultaneously most uniform particles were obtained in the DVB–toluene–nonionic-tensides system. In a second approach, poly-MMA (PMMA) particles were used to build aggregates with bigger polymer particles. For this purpose, tripropyleneglycolediacrylate (TPGDA) particles were synthesized in a microfluidic co-flow arrangement and polymerized by light- irradiation. Then, PMMA particles were assembled at their surface. In a third step, these composites were dispersed in an aqueous acrylamide–methylenebisacrylamide solution, which again was run through a co-flow-device and photopolymerized. As such, entities consisting of particles of three different size ranges—typically 0.7/30/600 µm—were obtained. The particles synthesized by both approaches are potentially suitable for loading with or incorporation of analytic probes or catalysts such as dyes or metals.

Ice formation on the surface of outdoor equipment brings significant inconvenience to human life and production. Superhydrophobic materials with the micro-nanostructure are considered to be effective anti-icing materials. However, repeated icing and deicing processes will destroy the structure and lose anti-icing properties. Herein, low-cost, durable, high-efficiency photothermal superhydrophobic materials were prepared by electrochemical deposition and silanization treatment methods. Combined with the black-body property of carbon materials and the micro-nano hierarchical structure, the as-prepared material has excellent photothermal and superhydrophobic properties. The surface temperature can rise to 90 °C, and the freezing droplets can melt in 100 s under 100 mW/cm 2 of sunlight illumination. The superhydrophobic property endows the material with excellent anti-icing performance, and the icing delay time is as long as 3600 s. The melted water droplet can quickly roll off due to the low adhesion of the superhydrophobic surface, which avoids the refreezing of the melted droplet and enhances the photothermal conversion performance. We innovatively use the elemental tracer method to understand the melted water droplet roll off mechanism on inclined surfaces. In addition, the heat transfer model of anti-icing and photothermal deicing processes are established to confirm that the heat required for melting ice during the deicing process is mainly generated by photothermal materials. Finally, the feasibility of practical application of the material was verified by the anti-icing/ deicing experiment of a wind turbine blade and ice/frost layer melting experiment. It concludes that the superior anti-icing and deicing properties are realized using the high photothermal conversion and excellent superhydrophobic properties of the prepared photothermal superhydrophobic materials. This study provides a perspective for constructing micro-nano hierarchical structures on the surface and combining them with the abundant solar energy in nature to develop photothermal anti-icing materials for practical application.

Ice accretion on exposed surfaces is unavoidable as time elapses and temperature lowers sufficiently in nature, causing detrimental impacts on the normal performance of devices and facilities. To mitigate icing problems, both active de‐icing and passive anti‐icing materials (AIM) have been utilized. Traditional active anti‐icing methods suffer from energy consumption, low efficiency and high cost, while passive AIM meet the challenges of improving mechanical durability and maintaining low ice adhesion strength during icing/de‐icing cycles. Recently, new AIM are rationally designed by the combination of passive anti‐icing and active de‐icing, exhibiting efficient, reliable and energy‐saving properties. The conceptual idea is that passive AIM only need to reach a certain value of ice adhesion strength (i.e., τice<100 kPa) instead of achieving lowest ice adhesion strength, and simultaneously combine with active de‐icing techniques (i.e., electro‐thermal and photo‐thermal stimulus) to realize ideal all‐weather anti‐icing/de‐icing. In this review paper, the authors provide a brief introduction to passive AIM, and mainly focus on recent advances in the electro‐/photo‐thermal promoted AIM in terms of anti‐icing/de‐icing mechanisms, challenges and perspectives. The new conceptual anti‐icing/de‐icing strategy will inspire the rational design of the state‐of‐the‐art AIM in future and provides practical solutions to mitigate outdoor anti‐icing/de‐icing problems in daily lives.
