Ultralight, high-performance electromagnetic interference (EMI) shielding graphene foam (GF)/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) composites are developed by drop coating of PEDOT:PSS on cellular-structured, freestanding GFs. To enhance the wettability and interfacial bonds with PEDOT:PSS, GFs functionalized 4-dodecylbenzenesulfonic acid. The GF/PEDOT:PSS possess an ultralow density 18.2 × 10-3 g/cm3 a high porosity 98.8%, as well enhanced electrical...
Monolayer graphene oxide (GO) sheets with sizes ranging from a few to ∼200 μm are synthesized based on chemical method and sorted out obtain four different grades having uniform sizes. Transparent conductive films produced using the ultralarge (UL-GO) that deposited layer-by-layer substrate Langmuir-Blodgett (LB) assembly technique. The density degree of wrinkling UL-GO monolayers turned dilute, close-packed flat wrinkles (GOWs) concentrated (CGOWs) by varying LB processing conditions....

This study demonstrates that large-size graphene oxide (GO) sheets can impart a tremendous positive impact on self-alignment, electrical conductivity, and mechanical properties of papers. There is remarkable, more than 3-fold improvement in conductivity the papers made from ultralarge GO (with an average area 272.2 μm(2)) compared to small counterpart 1.1 μm(2)). The corresponding improvements Young's modulus tensile strength are equally notable, namely 320% 280%, respectively. These bulk...
Abstract Vigorous development of 5G communication technologies can boost mobile networks yet bring in electromagnetic interferences and safety concerns utilizing electronic devices. Particularly, network not only involve a low‐frequency band n 78 (3.3–3.8 GHz) but also cover multi‐frequency bands 77 (3.3–4.2 79 (4.4–5.0 GHz), displaying multiple radiations. Countless efforts have been devoted to investigating wave (EMW) absorbers with low‐ multi‐band absorption properties. However, terms...

Flexible multidirectional strain sensors are crucial to accurately determining the complex states involved in emerging sensing applications. Although considerable efforts have been made construct anisotropic structures for improved selective capabilities, existing suffer from a trade-off between high sensitivity and stretchability with acceptable linearity. Here, an ultrasensitive, highly sensor is developed by rational design of functionally different layers. The bilayer consists aligned...
