The ultrasensitive piezoelectric sensors with the capability of sound recognition have attracted extensive attention due to their unique characteristics. However, fabrication acoustic favorable flexibility and sensitivity via simple controllable methods remains a significant challenge. Herein, an adaptive sensor based on polyimide (PI) composite foams containing fluorine groups is developed. uniform porous morphology endows foam-based remarkable 0.9536 V/N over broad pressure range (2.5–12.5...

High-performance and light-weight polymer foams with ultralow dielectric constant, good thermal stability, high mechanical strength are greatly needed in aviation aerospace fields. In this work, cross-linked rigid polyimide (PI) composite were fabricated based on norbornene terminated polyamide ester oligomer precursor powders via foaming method. The obtained PI exhibit outstanding characteristics of light weight (90–130 kg·m–3) strength. When the glass fiber (GF) loading was 10 wt %,...

With the rapid development of 5G communication technologies, high-performance electromagnetic interference (EMI) shielding materials with less secondary reflection for electronic devices have become an urgent demand in recent years. In this study, flexible open-cell polyimide (PI) foams containing graphene nanoplatelets (GN)/Fe3O4 coatings absorption-dominated EMI were fabricated. The result shows that efficient (EMI SE) composite foam PI/GN/Fe3O4 (PF/GN/Fe3O4) can achieve 60.6 dB a...

The application of traditional isocyanate-based polyimide (PI) foams is highly hindered due to limited flame retardancy, poor mechanical properties, and relatively single functionality. Herein, we propose an effective method fabricate dual cross-linked polyimide/bismaleimide (PI-BMI) with outstanding heat resistance enhanced properties by incorporating bis(3-ethyl-5-methyl-4-maleimidophenyl)methane (ME-BMI) as the interpenetrating network. results show that prepared PI-BMI composite exhibit...

Electromagnetic interference (EMI) -shielding and microwave-absorbing materials are of great significance in the fields microelectronics telecommunication to achieve electromagnetic protection compatibility. However, it still remains a challenge design fabricate integrating both microwave absorbing shielding properties. In this study, we prepared fluffy porous EMI via facile vapor deposition pyrrole (Py) on commercial polyamide fibrous mats (FMs). The uniform polypyrrole (PPy) coating fiber...

Abstract Despite its tremendous influence in the early eleventh century, Xikun poetry was essentially written out of main literary historical narratives Northern Song dynasty. When it does appear such narratives, is usually used as a foil to set up reputedly real grand beginnings generation led by Ouyang Xiu. This article takes another look at phenomenon, arguing that poets' imitative works modeled on Late Tang poet Li Shangyin, we see burgeoning interest creating more internally consistent...

In this informed and knowledgeable study of an important but much-neglected genre traditional Chinese poetry, Fusheng Wu offers insightful reading, critical acumen, analytical sophistication. With its attention to individual poems sustained interest in uncovering the human drama behind composition poems, epitomizes poetic criticism. It will not only “compel us reexamine tradition” (p. 1) from a new perspective furnished by unusual genre, also enrich our understanding key aspect lives many...

With the rapid development of 5G communication technologies, electromagnetic interference (EMI) shielding for electronic devices has become an urgent demand in recent years. Not only EMI but also high waves (EW) absorption properties are required to reduce and avoid secondary reflection. The purpose this study is achieve integrating effects microwave absorbing by impregnating flexible open cell polyimide (PI) foams with hybrid graphene (GO) containing Fe3O4 component. results show that...
