“…Furthermore, by employing a pencil hardness test, the EMS layer possessed a pencil hardness of 2H, indicating a reasonable hardness in abrasion resistance. 58,59 It has been demonstrated that a sticky superhydrophobic surface has great advantages in many industrial applications, such as microsample analysis, 17,18,60 and droplet-based microreactors. 23,61−63 The key techniques of these applications are based on the effectiveness of transporting a droplet from one surface to another.…”

A series of sticky superhydrophobicity surfaces with high water contact angle and high water adhesive force is facilely prepared via an all-solution-processed method based on polymerization-induced phase separation between liquid crystals (LCs) and epoxy resin, which produces layers of epoxy microspheres (EMSs) with nanofolds on the surface of a substrate. The morphologies and size distributions of EMSs are confirmed by scanning electron microscopy. Results reveal that the obtained EMS coated-surface exhibits high apparent contact angle of 152.0° and high water adhesive force up to 117.6 μN. By varying the composition of the sample or preparing conditions, the sizes of the produced EMSs can be artificially regulated and, thus, control the wetting properties and water adhesive behaviors. Also, the sticky superhydrophobic surface exhibits excellent chemical stability, as well as long-term durability. Water droplet transportation experiments further prove that the as-made surface can be effectively used as a mechanical hand for water transportation applications. Based on this, it is believed that the simple method proposed in this paper will pave a new way for producing a sticky superhydrophobic surface and obtain a wide range of use.

“…Large amounts of sulfonates and dispersants were added to the formulations, and they were less resistant to acidity and salt. The increase in the content of silicone surfactants in the condensate demulsifier increases the silicon content of the condensate, thereby reducing the condensate quality [17,18]. In addition, the demulsifier formulations have variable and complex components, and generally have poor stability [19].…”

Organic amine and nanosilica were combined to create a nano-demulsifier, which was employed in the oil–water separation process of a condensate emulsion. The nano-demulsifier has the structure of hyperbranched polymers and the skeleton structure of hyperbranched nanomaterials, and displays the demulsification impact of organic amine polymers as well as the synergistic effect of nanomaterials. This nano-demulsifier has the potential to drastically reduce the quantity of condensate demulsifiers utilized in the gathering station. The dehydration rate of the condensate lotion in the gas gathering station can reach more than 95% only at a concentration of 1.0 wt.%. Its application can significantly increase the separation efficiency of the condensate emulsion as well as the quality of condensate oil. It has a positive impact on cost reduction and efficiency in gas well production. The mechanism of action of the demulsifier was also studied, and the results show that the demulsifier is a phase reverse demulsifier.

known that the optical properties related refractive index is an important parameter for ordered micro/nanostructures. Commonly, organic substances own lower refraction. Aiming at improving which, researchers introduce highly polarizable heteroatoms or rigid aromatic moieties. However, the maximum of refractive index is limited to 1.54-1.60, [3] which is far from the requirements of rapidly developing technologies. [4] Incorporation of inorganic materials with relative higher refractive index (TiO 2 , ZnO, ZnS, graphene nanoparticles, and Si) into an organic matrix is capable of enlarging the optical parameters to a great extent, generally up to a value of 2.5-3.0, [5] which offers more chances for the fabrication of novel ordered micro/nanostructures. Photonic crystals (PCs), for example, regularly arrange materials of high and low dielectric constants on the order of the wavelength of light. The photonic bandgap (PBG) prohibiting the propagation of light results from the sufficient dielectric contrast and appropriate geometry. The structural color therefore generates. Manipulating the propagation of light via micro/nanostructures meets the requirements for modern optical devices. [6] As a result, more efforts have been applied to devices consisting of micro/nanostructures of multiple materials, such as synthetic materials and biomaterials. [7] Besides optical properties, the strength and toughness of ordered micro/nanostructures are also improved based on the hybrid material. Meanwhile, the electric and magnetic features of inorganic dopants can also exactly assist the adjustability. Therefore, the hybrid can significantly improve performance compared with its constituent.This review emphasizes on applications sought (sensing, imaging, communication, photoelectricity, etc.), the materials used (silicon, metals, polymers, etc.), and the preparation methods employed (patterning, etching, deposition, etc.). We present an attempt to classify and compare some intensively reported micro/nanostructures of hybrid materials and/or heterogeneous structures, along with recent important developments in literatures. It is organized as follows: First, we summarize some fundamental physical principles and concepts in brief. Second, we particularly highlight artificial and natural laminar structures, represented by Bragg stacks (BSs) and butterfly wings, which have drawn much attention in the latest literatures. Next, the focus shifts to the preparation routes and materials adoption of colloidal crystals and their derived periodic arrays. A few examples of highly functional materials Recent advances in manufacturing and technology of ordered hybrid micro/ nanostructures have acquired many breakthroughs. With the aid of the cooperation of various materials, the ordered hybrid micro/nanostructures exhibit high-quality performance and mechanical stability and allow the modulation on the light-matter interaction in a controllable manner, thereby enabling a wide variety of innovative applications.
