Microcapillary films (MCFs) are microextrusion-processed plastic films containing an array of parallel microcapillaries, and have been widely utilized as microfluidic platforms. However, the nonuniform size distribution within a single MCF strip limits the application of MCFs in monodisperse droplet generation. In this paper, we first clarify the mechanisms that lead to uneven microcapillary dimensions

Conductive hydrogels have received widespread attention in the applications of biosensors, human-machine interface, and health recording electrodes. Herein, the conductive hydrogels integrated anti-freezing, water retention, reusable, and sensing performances were fabricated by introducing polyvinyl alcohol (PVA), cellulose nanofibril (CNF), MXene nanosheets, and glycerol. The as-prepared hydrogels

Chain entanglement, either cohesional or topological, distinguishes polymers from other engineering materials. It impedes the movement of molecular segments and influences the polymer rheology, morphology, and mechanical properties. Although a high level of entanglement could increase the polymer toughness, excessive entanglement should be avoided because it causes a high melt viscosity making the

In this study, we synthesis a kind of imidazole type poly(ionic liquid) ([PEP-MIM]Cl) which can disperse carbon effectively. [PEP-MIM]Cl is used as an intermediate to coat carbon on the poly(acrylic acid)(PAA-co-MBA) via ion exchange to obtain conductive polymer composite (CPC). A series of characterizations are performed. Experiments show that carbon can be coated on the PAA-co-MBA uniformly, and

The correct sentence should read: “The ratio of the width of the grip section to the width
