“…At present, superior solar evaporators have been proposed to achieve significantly high evaporation rates by reducing the water evaporation enthalpy. [32][33][34][35][36][37] By regulating the hydrophilic functional groups, the interactions between water and water transportation materials as well as the evaporation enthalpy could be elaborately tailored. For instance, by penetrating polystyrene sulfonate networks into polyvinyl alcohol (PVA) hydrogel, Yu's group construct an excellent PVA hydrogel-based solar evaporator with a high evaporation rate of 3.86 kg m −2 h −1 .…”

“…For example, carbon materials, plasmonic materials, semiconductors, polymeric materials, metalorganic frameworks, and covalent organic frameworks with high light absorbance (>95%) are selected as the photothermal materials. [16][17][18][19][20][21] For water transportation materials, natural materials (such as wood, mushroom, radish, bamboo, luffa sponge, corn straw, and so on) [22][23][24][25][26][27] and artificial materials (such as membranes, aerogels, and hydrogels) [28][29][30][31][32][33][34][35][36][37] are adapted to supply water.…”

To alleviate the severe water crisis, an interfacial solar evaporator provides a promising method to produce freshwater. Although many superior solar evaporators present high evaporation rates by reducing the water evaporation enthalpy, adapting sustainable materials to construct high‐efficiency solar evaporators remains challenging. Herein, inspired by the corncob pith's structure and functional groups, interconnected porous cellulose hydrogel is proposed by crosslinking sustainable hydroxypropyl cellulose. Benefiting from the porous structure and abundant hydroxy group, the corncob pith/carbon nanotubes (CNTs) and cellulose hydrogel/CNTs evaporators show a low evaporation enthalpy of 880.5 ± 42.1 and 1280.7 ± 57.8 J g−1 due to the reduced hydrogen bond numbers between water molecules and enable evaporation rates of 3.06 and 2.56 kg m−2 h−1, respectively. Moreover, the evaporators present superior purification performance for seawater and sewage, and show excellent anti‐biological fouling properties under light irradiation. It is anticipated that the bionic strategy would provide an in‐depth understanding of designing next‐generation sustainable solar evaporators in the framework of the dual‐carbon concept.

Interfacial solar steam generation (ISSG) is the main method to get fresh water from seawater or wastewater. The balance between evaporation rate and salt resistance is still a major challenge for ISSG. Herein, a wood aerogel island solar evaporator (WAISE) with tunable surface structure and wettability by synthesizing poly(n‐isopropylacrylamide)‐modified multi‐walled carbon nanotube photothermal layers. Compared to dense surface structure evaporators, interfacial moisture transport, thermal localization, and surface water vapor diffusion of WAISE are greatly promoted, and the evaporation rate of WAISE increased by 87.64%. WAISE allows for record performance of 200 h continuous operation in 20% NaCl solution without salt accumulation. In addition, the photo‐thermal‐electric device is developed based on WAISE with continuous water purification, power generation, and irrigation functions. This work provides a new direction for the development of multifunctional water purification systems.

“…They are insoluble in both water and organic solvents and have unique properties. They can absorb amounts of water that are hundreds or even thousands of times heavier than their own weights, and the gels formed after water absorption and swelling have enhanced water retention capacity and weather resistance [14][15][16]. Water-absorbent resins can absorb water and swell in a lost circulation formation, possess good deformability and anti-dilution properties, and can effectively plug a lost circulation formation via the dual effects of filling/plugging and squeezing/compacting.…”

Aiming at the complex strata, lost circulation often occurs. and lost circulation control becomes a difficult issue. A drilling fluid loss accident delays the drilling progress and even causes major economic losses. If we take a self-made sodium polyacrylate grafting and modify a starch water absorbent resin, using an amphiphilic compatibilizer as raw material through mechanical blending and chemical compatibilization, we can synthesize a resin–rubber blend swelling lost circulation material. This material presents a good resistance to anti-high-temperature performance, but the quality declines while the temperature is higher than 363 °C, and with the increasing temperature, the water-swelling expansion ratio becomes higher. The range of the water-swelling expansion ratio is 8 to 25 times and the water swelling rate becomes larger along with the reduced diameter of the lost circulation materials and decreases with the increasing salinity. The resin-rubber blend swelling lost circulation material after water swelling has excellent toughness and high elastic deformation capacity, thus, forming a 7 Mpa to 2 mm fracture via expansion, extrusion, deformation, and filling, which presents a good performance for fracture plugging and realizes the purpose of lost circulation control.
