“…The advancing contact angles were calculated as the water was pumped in until the baseline of the droplet started to move. At the same time, the receding angles measured with the water pumped out of the droplet, and the baseline began to shrink [29][30]. The WCR of the eight samples was attained in the lab using a humidifier to emulate the fog.…”

The continuous growth in the human population and climate change exacerbates the problems related to water scarcity. Harvesting the atmospheric water can mitigate the water scarcity in many regions around the globe. Fog collection using hybrid hydrophilic-superhydrophobic surfaces has the capacity to achieve a higher water collection rate. In this paper, a new method and materials are introduced to create the hybrid surfaces. The method includes additive manufacturing- to make sheets with holes-, mixing and casting polymeric matrix composite, and a controlled spray coating mechanism. The materials comprised of hydrophobic coating on top of the acrylic printed sheet and hydrophilic composite. The ratios of the pitches to diameters of the hydrophilic regions varied during the experiments to obtain the best water generation. The water collection rate for the sample with diameters of 583 um and a pitch of 1600 um has achieved 57% more than the untreated hydrophilic sample. The contrast in wettability accomplished by this novel method has the potential to be implemented on a large scale for atmospheric water harvesting.

“…Contact angle measurement is an effective and simple way to characterize surface wetting, which has been widely used in biological and technological systems. Generally, the contact angle can be determined by recording the video of a water drop on a solid surface, and then the Young equation is introduced to explain the results (Huhtamäki et al 2018). This type of determination could work on the wettability of CMC handsheets as well, which is well practiced in the literature.…”

Sodium carboxymethyl cellulose (CMC) is a major cellulosic derivative that has a wide variety of applications. The solubility of CMC is affected by the degree of substitution (DS) of carboxymethyl groups and their distribution along the CMC molecular chain. In this study, an enzymatic hydrolysis technique was used to determine the distribution of carboxymethyl substituents. Two key parameters, namely the average length of the molecular chain segments not susceptible to enzymatic hydrolysis by cellulases (L ̅Sn, including chains fully substituted or containing single unsubstituted unit) and the average length for the molecular chain segments susceptible to enzymatic hydrolysis (L ̅Gn, unsubstituted chains segments), were obtained. This approach was subsequently applied to characterize four CMC samples having similar DS values (~0.80). The distributions of carboxymethyl substituents along the CMC molecular chain were found to be drastically different. The L ̅Sn varied from 9.6 to 49.5, while the L ̅Gn was almost constant (from 4.5 to 5.4). This information was correlated to the CMC solubility. The swelling ratio and the dynamic contact angle revealed that the CMC samples with higher L ̅Sn exhibited stronger swelling and wettability than those with lower L ̅Sn. The dissolving time of the CMC molecule decreased substantially with the increase in L ̅Sn.

“…The influence of the length or nature of the alkyl chain on the surface activity of ionic liquids is well known. , Studies have shown that the length of the carbon chain in a surfactant impacts the interfacial properties, which translates into a significant reduction in surface tension and excellent wetting ability. , Continuing this thought, to contribute toward understanding the wetting phenomenon, the values of contact angle (CA) are established experimentally. The CA values are very useful for characterizing droplets deposited on a surface − and are determined by interactions in the liquid (forming the droplets), which spreads not only on the plant surface under consideration but also on the area covered by the herbicide spray. The CA values are crucial for determining the type of interaction between a test surface and a wetting compound. , Surface properties are an important influence factor for the effectiveness of HILs, because the physical and chemical attributes of HILs can result in different effects on a leaf surface.…”

A series of piperidinium-based herbicidal ionic liquids (HILs) were synthesized and investigated. The designed HILs, obtained with high yields, consisted of cation 1-alkyl-1-methylpiperidinium with surface activity and a commercially available herbicidal anion: (3,6-dichloro-2-methoxy)benzoates (dicamba). The above-mentioned compounds were characterized in terms of surface activity and phytotoxicity. Preliminary results were obtained at higher wettability for all HILs when compared to the wettability of commercial Dicash, with HIL having 18 atoms in the carbon chain being the best effectiveness in wetting surfaces (weeds and crop leaves), whereby a drop of HILs with short alkyl chains (C 8 −C 10 ) could not slide down a leaf. Our findings present that wettability or mobility of HILs drops varied depending on the plant species. Moreover, in this study, by zeta potential and atomic force microscopy measurements, we provide conclusive evidence to demonstrate that alkyl chain elongation plays a significant role in the evolution of surface properties of HILs.
