“…When the electromagnetic wave strikes the frame surface, a large part is reflected because of the high electron carrier density of the conductive MG frame. The incident wave is repeatedly scattered and diffracted inside the hierarchical porous structure, greatly extending the wave propagation path and leading to effective energy dissipation [53,54]. In addition, the electromagnetic wave-activated electrons in the MG frame can migrate along the conductive filaments and jump across the interfaces or defects, generating microcurrents inside the filaments that would be beneficial for absorbing and dissipating the electromagnetic energy in the form of thermal energy [55,56].…”

Highlights 3D printing of MXene frames with tunable electromagnetic interference shielding efficiency is demonstrated. Highly conductive MXene frames are reinforced by cross-linking with aluminum ions. Electromagnetic wave is visualized by electromagnetic-thermochromic MXene patterns. Abstract The highly integrated and miniaturized next-generation electronic products call for high-performance electromagnetic interference (EMI) shielding materials to assure the normal operation of their closely assembled components. However, the most current techniques are not adequate for the fabrication of shielding materials with programmable structure and controllable shielding efficiency. Herein, we demonstrate the direct ink writing of robust and highly conductive Ti3C2Tx MXene frames with customizable structures by using MXene/AlOOH inks for tunable EMI shielding and electromagnetic wave-induced thermochromism applications. The as-printed frames are reinforced by immersing in AlCl3/HCl solution to remove the electrically insulating AlOOH nanoparticles, as well as cross-link the MXene sheets and fuse the filament interfaces with aluminum ions. After freeze-drying, the resultant robust and porous MXene frames exhibit tunable EMI shielding efficiencies in the range of 25–80 dB with the highest electrical conductivity of 5323 S m−1. Furthermore, an electromagnetic wave-induced thermochromic MXene pattern is assembled by coating and curing with thermochromic polydimethylsiloxane on a printed MXene pattern, and its color can be changed from blue to red under the high-intensity electromagnetic irradiation. This work demonstrates a direct ink printing of customizable EMI frames and patterns for tuning EMI shielding efficiency and visualizing electromagnetic waves.

“…Owing to their superior qualities, such as light weight, good processability, good environmental stability, and tunable morphology [ 5 , 6 , 7 ], conductive polymer nanocomposites have been explored as an alternative to metal shields for the last 10 years. Conductive polymer composites are the multi-phase composites obtained by adding electrical nanofillers (such as graphene, carbon nanotube, MXenes, etc.,) into the polymer matrix using specific processing technologies.…”

“…Nevertheless, a primary drawback for applications of CNTs has been their cost, specially, if single-walled CNT is warranted. Similarly, most of the fillers used from graphene family, are economically non-viable, difficult to produce at bulk scale and often require purification, auxiliary treatment, and functionalization steps [ 6 , 7 ]. As an example, despite achieving high SE by reduced graphene oxide, transferring these scientific findings to industry has been hindered by the cost and the lack of a large-scale reduction method.…”

Polyester nanocomposites reinforced with graphene nanoplatelets (GnPs) with two different lateral sizes are prepared by high shear mixing, followed by compression molding. The effects of the size and concentration of GnP, as well as of the processing method, on the electrical conductivity and electromagnetic interference (EMI) shielding behavior of these nanocomposites are experimentally investigated. The in-plane electrical conductivity of the nanocomposites with larger-size GnPs is approximately one order of magnitude higher than the cross-plane volume conductivity. According to the SEM images, the compression-induced alignments of GnPs is found to be responsible for this anisotropic behavior. The orientation of the small size GnPs in the composite is not influenced by the compression process as strongly, and consequently, the electrical conductivity of these nanocomposites exhibits only a slight anisotropy. The maximum EMI shielding effectiveness (SE) of 27 dB (reduction of 99.8% of the incident radiation) is achieved at 25 wt.% of the smaller-size GnP loading. Experimental results show that the EMI shielding mechanism of these composites has a strong dependency on the lateral dimension of GnPs. The non-aligned smaller-size GnPs are leveraged to obtain a relatively high absorption coefficient (≈40%). This absorption coefficient is superior to the existing single-filler bulk polymer composite with a similar thickness.

“…Zero‐dimensional nanomaterials are referred to as quantum dots (QDs) and are the most extensively researched materials having a tremendous application value. They are semiconductor nanoparticles with diameters in the range of 2–10 nm 1–4. QDs are generally fabricated from elements of group II (Zn, Cd), VI (Se, S), III–V, and IV–VI of the periodic table.…”

Biomass‐derived Carbon Quantum Dots – A Review. Part 1: Preparation and Characterization

View full text Add to dashboard Cite

The preparation of nanostructured carbon materials from chosen biomass through hydrothermal carbonization and pyrolysis processes by optimizing the reaction conditions is one of the bases for applying the product in certain of the development activities. The finished product more or less reflects the raw material and the way of preparation. Among the many products, carbon quantum dots (CQDs) have gained importance due to their bolstered characteristics and facile preparation. CQDs are zero‐dimensional (0D) nanomaterials which attracted attention in the recent past due to their excellent water solubility, unique optical properties, good electrical conductivity, eco‐friendliness, and biocompatibility. Small‐sized CQDs offer high surface area per unit volume, strong tunable fluorescence, photo‐luminescent emissions, and semiconducting properties. In this paper, identification of ideal raw materials, process parameters being followed in the preparation of CQDs through hydrothermal carbonization and pyrolysis techniques, and the properties of the resultant CQDs commensurate with the nature of process are reviewed.
