Wetting enhancement of polypropylene plate for falling film tower application

Efficient Synthesis of α-FeOOH from Pickling Wastewater in Falling Film Tower and Its Kinetics

“…The red line in the figure is the circulation path of the reaction solution, and the blue line is the circulation path of insulated water. The falling film tower has attracted extensive attention due to its characteristics of small temperature difference and high mass transfer efficiency. , In addition, there are no moving parts inside; the structure is simple and not easy to block, thus avoiding the shortcomings of the packed tower, such as large gas–liquid resistance and gas–liquid interception. , At present, there are few studies on the synthesis kinetics of α-FeOOH and even less on the macrokinetics considering the influence of mass transfer. Domingo et al studied the oxidation kinetics of different iron oxides.…”

Experimental study on dehumidification performance enhancement by TiO 2 superhydrophilic coating for liquid desiccant plate dehumidifiers

“…The investigation of the internallycooled liquid desiccant dehumidifier has been carried out by many researchers [8][9][10][11][12]. As the dehumidification performance is critical to LDAC system, many researchers have developed various methods to improve the performance [13][14][15][16][17][18][19][20][21][22][23][24][25][26]. These methods can be mainly divided into the following categories, surface treatment [13][14][15][16][17], addition of surfactant or nano-particles [18][19][20][21][22][23] and structure modification of dehumidifiers [24][25][26].…”

Preparation of Stable Wetting Surface by Hyperthermal Hydrogen Induced Cross-Linking of Poly(acrylic acid) on Poly(chloro-p-xylylene) Film

“…This surface characteristic can lead to poor surface wetting and adhesion failure of the coating on the films, thereby seriously limiting the wide applications of polymer films. 5,6 For example, poly(chloro-p-xylylene) (PPXC) film prepared by chemical vapor deposition (CVD) polymerization of chloro-p-xylylene, is often used for the encapsulation of semiconductor and bioimplant devices due to its excellent moisture barrier, anticorrosion, and biological compatibility. 7,8 However, its surface hydrophobicity leads to poor wetting with electrolyte and the difficulty in building functional electrodes on the PPXC film.…”

“…As petroleum-based polymer films were widely used in the fields of food and electronic packing, substrates for printing, water treatment, and biomedical health, their surface properties have received more and more attention. − The common polymer film surface often exhibits low surface energy and high hydrophobicity because of its hydrocarbon structure and the absence of hydrophilic groups. This surface characteristic can lead to poor surface wetting and adhesion failure of the coating on the films, thereby seriously limiting the wide applications of polymer films. , For example, poly­(chloro- p -xylylene) (PPXC) film prepared by chemical vapor deposition (CVD) polymerization of chloro- p -xylylene, is often used for the encapsulation of semiconductor and bioimplant devices due to its excellent moisture barrier, anticorrosion, and biological compatibility. , However, its surface hydrophobicity leads to poor wetting with electrolyte and the difficulty in building functional electrodes on the PPXC film. , …”
