Natural rubber toughened carbon nanotube buckypaper and its multifunctionality in electromagnetic interference shielding, thermal conductivity, Joule heating and triboelectric nanogenerators

Sodium alginate based skin-core fibers with profoundly enhanced moisture-electric generation performance and their multifunctionality

“…Using the previously reported method, [22][23][24] a MWCNT dispersion of 1 wt% was prepared by ball milling and sonication using CMCNa as the dispersant. The dispersion aer pretreatment was volatilized to 10 wt% by magnetic stirring at 80 °C to obtain a spinning solution for the core layer of ber.…”

Layer‐by‐Layer Assembly of Multifunctional NR/MXene/CNTs Composite Films with Exceptional Electromagnetic Interference Shielding Performances and Excellent Mechanical Properties

“…When the content of NR/MXene layer is 50%, the average EMI SE of multilayer NR/MXene/CNTs is up to 49.9 dB in the frequency range of 8.2-12.4 GHz, the highest among all the multilayer films, and the value is much higher than the required value of 20 dB for commercial EMI shielding applications. [43] Figure 4b shows the reflection, absorption, and transmission value of EMI SE for multilayer NR/MXene/CNTs films with different MXene content, and these values are marked as SE R , SE A , and SE T , respectively, and the values of SE R , SE A , and SE T are calculated according to Equations (S1-S6, Supporting Information). Apparently, the values of SE A of all the samples are all higher than the values of SE R , there are about 30% to 40% of electromagnetic waves (EMW) are reflected away, the majority of EMW entering NR/MXene/CNTs composite films are absorbed (the proportion is about 60% to 70%), which indicate that the absorption of EMW is the main mechanism of EMI shielding for multilayer NR/MXene/CNTs composite films, and the values of SE A and SE T all increase with the increase of MXene content.…”

Energy harvesting and temperature sensing thermoelectric devices based on the carbon template method

“…Carbon-based/PEI self-supporting films were prepared according to reported method. [25][26][27] MWCNTs were ground and then dispersed in 0.25 mg/ml of Triton X-100 aqueous solution to form a uniform dispersion (0.5 mg/ml) with the help of stirring and sonication. Homogeneous MWCNT/water dispersion of 40 g was vacuum filtered through a cellulose filter film (pore size of 0.45 μm) to obtain a piece of deposited MWCNT.…”

“…The CNT films exhibited good flexibility, electrical conductivity, Joule heating properties, and electromagnetic shielding properties. [25][26][27] The microstructure and electrical conductivity of the conductive network formed by the entanglement of carbon nanomaterials are ultimately controlled by vacuum filtration process, which will inevitably have a significant impact on the subsequent PEI doping and resultant thermoelectric property. Therefore, the conductive network template will be pre-prepared using carbon nanomaterials by vacuum filtration method to ensure the conductivity of the PEI-doped p-junction material in this study.…”
