In recent years, functional fluidic electrohydrodynamic (EHD) pumps have attracted considerable attention due to their remarkable features, such as simple structure, quiet operation, and energy-efficient utilization. EHD liquid pumps can be used in various industrial applications, like flow transfer, thermal management, and actuator drive. In this paper, the author reviewed EHD liquid pump research in these specific aspects: the first observation of the EHD effect, its mathematical modeling, and the choice of pump structure, electrode configuration, and working medium. Based on the review, a summary of the development and latest research on EHD pumps can be provided for the readers.

“…Polymers are attracting widespread interest for use in medical devices because of their high chemical resistance, biocompatibility, and optical transparency and low cost (lower than that of glass or silicon). Various polymeric materials, such as photoresist (model:SU-8) [1], poly(dimethyl)siloxane [2], polyimide [3], and poly-(para-chloro-xylylene) (Parylene C), have been investigated as packaging materials in many applications, including consumer electronics, lab-on-a-chip analysis, and prosthetic devices [4].…”

The use of poly-(para-chloro-xylylene) (Parylene C) in microelectromechanical systems and medical devices has increased rapidly. However, little research has been conducted on the wettability and surface roughness of Parylene C after being soaked in solutions. In this study, the contact angle and surface roughness (arithmetic average of roughness) of Parylene C on three-dimensional (3D)-printed photopolymer in 10% sodium hydroxide, 10% ammonium hydroxide, and 100% phosphate-buffered saline (PBS) solutions were investigated using a commercial contact angle measurement system and laser confocal microscope, respectively. The collected data indicated that 10% ammonium hydroxide had no major effect on the contact angle of Parylene C on a substrate, with a Shore A hardness of 50. However, 10% sodium hydroxide, 10% ammonium hydroxide, and 100% PBS considerably affected the contact angle of Parylene C on a substrate with a Shore A hardness of 85. Substrates with Parylene C coating exhibited lower surface roughness than uncoated substrates. The substrates coated with Parylene C that were soaked in 10% ammonium hydroxide exhibited high surface roughness. The aforementioned results indicate that 3D-printed photopolymers coated with Parylene C can offer potential benefits when used in biocompatible devices.

“…The high thermal stability of polyamide plastics derives from their strong hydrogen bonding between the chain and the crystal structure allowing their application in a high temperature environment. Polyamides are additionally also widely used as membrane materials, 5–8 modifiers for some resins, 9–11 composites, 12 metal organic frameworks for expansion and functionalization, 13,14 and can also be possibly used as adhesives 15 …”

[16][17][18] They are thus heated into a viscous fluid before application and spread on the surfaces of the bonded objects.…”

Thermosetting polyamide resins prepared by reacting citric acid with hexanediamine (CH) were synthesized and used for plywood bonding in this work, and the effects of reaction time, molar ratio of citric acid, and hexanediamine on the bonding performance have been studied. Fourier transform-infrared (FT-IR) and liquid chromatography-mass spectrometry (LC-MS) were used to determine the structures of the resins. Differential scanning calorimeter (DSC), dynamic mechanical properties (DMA), and thermogravimetric analysis (TG) were used to analyze its thermal properties. The results show that amide bonds can be formed by the reaction of carboxyl and amino groups, which acted as reaction raw materials that can undergo further polycondensation to render possible the formation of a cured cross-linked network, thus to ensure the bonding performance of the adhesives. Meanwhile, CH adhesives presented excellent bonding strength and water resistance above the standard requirements (≥0.7 MPa). In particular, the plywood prepared by CH resin with molar ratio of citric acid to hexanediamine of 1:1.5 and reaction time of 3 h exhibited the best performance, the dry shear strength being as high as 1.96 MPa, 24 h cold water soaking strength of 0.87 MPa, and 3 h hot water (63 C) soaking wet strength attaining 1.24 MPa.
