Abstract Directed transportation and collection of liquids bubbles play a vital role in the survival ecosystems. Among them, optical response control is widely used fields microfluidic chips chemical synthesis because its high remote operation fast speed. However, due to poor light transmission, development direction traditional near‐infrared (NIR) absorbing materials field visualization limited, there are few reports manufacturing an operating platform that can realize directional movement droplets/bubbles on single platform. Here, transparent photo‐responsive PBFS prepared for droplet bubble manipulation by coating etched glass substrate with Prussian blue (PB) nanocubes. When irradiation platform, PB nanocubes trigger heat production photothermal means, action Marangoni force, surface tension left right sides droplets not uniform, forming gradient, thereby driving bubbles. The has good application potential microchemical reaction biomedical engineering brings new solutions materials.

A highly electrostatic cellulose acetate (CA)-based electret film for air filtration was fabricated by the electrospinning method assisted with corona charging technique in this work. The polar and hydrophobic poly(vinylidene fluoride) (PVDF) chosen as reinforcement. results showed that under dual electric fields, dipole charges generated from conversion a nonpolar α-phase to β-phase of inside PVDF space charge captured at phase end traps CA give CA/PVDF films high static electricity. Especially, composite 40 wt % exhibited an ultrahigh surface potential 2.146 kV excellent efficiency 97.27% PM 0.3 pressure drop only 88.7 Pa, which were 29.68 22.04%, respectively, higher than those pure film. It noticed hydrophobicity mechanical strength also improved.
