Abstract
En 中文
Surface energy, as an intrinsic property of solids, plays a crucial role in modulating the characteristics of solid surfaces, especially of the solid-liquid interface. Due to inevitable processes such as surface adsorption or contamination, the surface energy of practical solids is usually nonuniform. However, if this nonuniformity is rationally designed and effectively utilized, it is capable of endowing great potential for liquid manipulation. With the rapid development of microfabrication and surface modification techniques, a variety of artificial patterned surface energy surfaces (PSESs) have been fabricated, which extend the diversity, tunability, and precision of liquid-based applications. In this review, we discuss the regulation of solid-liquid interface properties with PSESs from a relatively macroscopic perspective, particularly focusing on how to control matter and energy through rational design. First, we provide a brief introduction about the definition and significance of PSESs. Then, matter selective adhesion by PSESs is summarized, including liquid dynamics regulation, crystallization inducement, and biosample self-distribution. In the following, we discuss how PSESs regulate physical fields, including the thermal field, electric field, and acoustic field, with an explanation centered on discontinuous solid-liquid contact on PSESs. Finally, associated challenges of surface energy regulation for liquid-based scenarios are included.
