“…Specially, multi-wall carbon nanotubes (MWCNTs), as a typical kind of carbon-based materials, show several advantages, such as light weight, low-cost, high conductivity, good chemical inertness and high-resistance to corrosion, which is believed to be beneficial to construct highly efficient, lightweight and economic microwave absorption materials in future. Therefore, Fe 3 O 4 /MWCNTs hybrids have been widely prepared by different methods, and their microwave absorption properties have been widely investigated [24][25][26][27][28]. However, the reported synthetic methods are complex.…”

“…Carbon nanotubes (CNT), which was discovered by Iijima in 1990s , have gained much interest over these few years in numerous applications owing to their unique structure, high aspect ratio, excellent thermal, mechanical strength, and chemical stability . Recently, combining CNT with polymer matrix has improved the electrical conductivity and mechanical properties that differ from those of the individual components .…”

Hexanoic acid (HA) doped polyaniline (PAni) nanocomposites which consist of different contents of untreated double wall carbon nanotubes (u‐DWNT) and carboxyl treated DWNT (c‐DWNT) with titanium dioxide nanoparticles were successfully prepared using template‐free method. Fourier transform infrared, ultraviolet‐visible and X‐ray diffractometer spectra clearly confirmed the chemical structure of PAni nanocomposites. Thermal stability, morphology, conductivity, magnetic properties and reflection loss of PAni nanocomposites were characterized by thermogravimetric analyzer, field emission scanning electron microscope, four‐point probe, vibrating sample magnetometer and microwave vector network analyzer, respectively. From this study, it is shown that electrical conductivity of PAni nanocomposites with u‐DWNT possessed higher conductivity (1.23 × 10–1 to 1.31 × 100 S/cm) compared to c‐DWNT (3.43 × 10–2 to 4.48 × 10–1S/cm). PAni/HA/TiO2/DWNT nanocomposites with 20% of c‐DWNT have been covered by PAni layers to form the highest amount of nanorods/nanotubes. Hence, it shows high heterogeneity that will enhance the dielectric permittivity and contribute to a more disordered motion of charge carriers along the PAni backbone. Therefore, it will eventually contribute to good microwave absorption and potentially apply as an efficient electromagnetic interference shielding material in cell phones. POLYM.

“…The synthesis of IONPs-MWCNTs was carried out by using the co-precipitation method [41][42][43]. MWCNTs were first treated by using a binary acid mixture of concentrated H 2 SO 4 and HNO 3 (volume ratio = 3:1) at 90 • C for 1.5 h, followed by washing them with distilled water.…”

In this study, we report a novel approach to fabricate an organic/inorganic magnetic hybrid system capable of self-healing, wherein a polycaprolactone-poly(furfuryl glycidyl ether) copolymer (PCLF) serving as the structure template was first synthesized, followed by the incorporation of iron oxide nanoparticles-decorated multiwalled carbon nanotubes (IONPs-MWCNTs) and 1,1′-(methylenedi-4,1-phenylene)bismaleimide (BMI) into the polymer matrix to form a covalently crosslinked hybrid network via a Diels−Alder (DA) reaction. For this system, the reactive combination of diene and dienophile from furan/maleimide, MWCNT/furan, and MWCNT/maleimide could facilely induce multiple DA reactions that imparted a versatile route to efficiently introduce IONPs-MWCNTs into the organic polymer hosts, resulting in a uniform distribution of IONPs-MWCNTs that led to a hybrid system with superparamagnetic properties. Beside the magnetic behavior, such material synergistically exhibited a superior ability for healing scratch defects via a retro-DA reaction. Therefore, this crosslinked PCLF/BMI/IONPs-MWCNTs hybrid system which exhibits multifunctional properties including superparamagnetic behavior and self-repairability can serve as an intelligent material for developing advanced electromagnetic applications.
