The synthesis of a family of new poly(lactic acid-co-glycerol monostearate) (PLA-PGC18) copolymers and their use as biodegradable polymer dopants is reported to enhance the hydrophobicity of poly(lactic acid-co-glycolic acid) (PLGA) nonwoven meshes. Solutions of PLGA are doped with PLA-PGC18 and electrospun to form meshes with micrometer-sized fibers. Fiber diameter, percent doping, and copolym...

Outdoor electronic equipment such as signal stations, radar units, and cellular base stations would benefit from electromagnetic interference (EMI) shielding systems, but ice accretion on the surface of these facilities often causes critical challenges, especially in cold regions winter season. In this study, icephobic nanocomposite electrospun membranes were developed via a two-step process re...

Composite coatings or films with polytetrafluoroethylene (PTFE) are typically utilized to offer superhydrophobic surfaces. However, the surfaces usually have limited durability, and require complicated fabrication methods. Herein, we report successful integration of PTFE ZnO ceramic achieve superhydrophobicity via one-step sintering method, cold process (CSP), at 300 °C. (1-x) ZnO–...

In this paper, a femtosecond laser removal model of PMMA was built, and the surface primary secondary microstructures were fabricated. The morphology wettability measured analyzed by an ultra-depth three-dimensional microscope contact angle measuring instrument. results showed that direct writing processing microstructure changed from hydrophilic state to hydrophobic state. Meanwhile, size para...
