“…With the increased in PANI content, the effective sites of conduction electrons inside the films also increased, gradually forming a conductive channel, which is conducive to the effective transfer of electrons. When the PANI dispersion content was 10%, the resistivity was 3.19E + 5 Ω·cm, which had a good antistatic effect, 55,56 and the best antistatic performance of the films when the PANI dispersion content was 45%, and the resistivity was 1.38E + 4 Ω·cm.…”

Damping coatings can convert kinetic energy into other forms of energy for consumption and have been widely used for vibration and noise reduction in rail trains, aerospace, automobile industry, and other fields. However, many aspects of damping coating such as, damping, water resistance, heat resistance, mechanical properties and antistatic properties require further improvement. In this study, a low‐cost conductive polyaniline (PANI) with a simple preparation method was dispersed in N‐methyl pyrrolidone and added to waterborne polyurethane‐acrylate (WPUA) hybrid latexes. The interfacial hydrogen bonding increases the interaction force between molecular chains, effectively improve the water resistance, heat resistance, damping, and mechanical properties of WPUA, and endowed WPUA with antistatic properties. Among them, PANI was used as an antistatic medium to be synthesized by chemical oxidation and doped with dodecylbenzene sulfonic acid, and the matrix polymer WPUA was the used of hydroxyethyl methacrylate (HEMA) to combine polyacrylate with waterborne polyurethane (WPU) by chemical bonds. The waterborne polyurethane‐acrylate‐polyaniline (WPUA‐PANI) films were investigated using dynamic light scattering , contact angle measurements , dynamic mechanical analysis, Fourier‐transform infrared spectroscopy (FTIR), digital highresistance meter and other characterization methods. It was concluded that the base latex has good stability, and when the PANI dispersion content was 35%, the comprehensive performance of the WPUA‐PANI films were the best, in which the maximum water contact angle was 106.8°, the tensile strength was increased from 0.7 MPa to 2.3 MPa, the effective damping temperature range (Tanδ ≥ 0.3) was increased from 50 °C to 87 °C, and the resistivity was reduced from 6.41E + 7 Ω·cm to 1.38E + 4 Ω·cm, which had better antistatic properties. This study will promote the development and application of damping coatings.

This work reports on tailoring the magnetic properties of acrylonitrile butadiene styrene (ABS)-based composites for their application in magnetoactive systems, such as magnetic sensors and actuators. The magnetic properties of the composites are provided by the inclusion of varying permalloy (Py—Ni75Fe20Mo5) nanoparticle content within the ABS matrix. Composites with Py nanoparticle content up to 80 wt% were prepared and their morphological, mechanical, thermal, dielectric and magnetic properties were evaluated. It was found that ABS shows the capability to include high loads of the filler without negatively influencing its thermal and mechanical properties. In fact, the thermal properties of the ABS matrix are basically unaltered with the inclusion of the Py nanoparticles, with the glass transition temperatures of pristine ABS and its composites remaining around 105 °C. The mechanical properties of the composites depend on filler content, with the Young’s modulus ranging from 1.16 GPa for the pristine ABS up to 1.98 GPa for the sample with 60 wt% filler content. Regarding the magnetic properties, the saturation magnetization of the composites increased linearly with increasing Py content up to a value of 50.9 emu/g for the samples with 80 wt% of Py content. A numerical model has been developed to support the findings about the magnetic behavior of the NP within the ABS. Overall, the slight improvement in the mechanical properties and the magnetic properties provides the ABS composites new possibilities for applications in magnetoactive systems, including magnetic sensors, actuators and magnetic field shielding.

“…However, pristine EP has many performance defects, such as flammability, poor toughness, and easy to accumulate static electricity 5 . In recent years, with the development of electronic industry, static electricity brings more and more harm to human beings 6 . Therefore, based on the increasing market demand, how to prepare high‐performance flame retardant and antistatic polymer composites has become a hot topic of great concern in academia and industry.…”

This work reports our recent efforts on the preparation of functionalized multi‐walled carbon nanotubes (f‐CNTs) and its application in improving the fire, conductive, and mechanical performance of epoxy resin (EP) composites in combination with graphite sheets (GSs). The addition of hybrid carbon nanomaterials can effectively improve the mechanical properties of epoxy. Consequently, when the mass fraction of f‐CNTs/GSs is 3.9 wt%, the limiting oxygen index (LOI) value is increased to 27.4%, and the tensile strength and notched impact strength of epoxy are increased by 33.5% and 44.8%, respectively. Increasing the content of carbon nanomaterials can further improve the flame retardancy and electrical conductivity of EP composites. For the sample containing 11.0 wt% f‐CNTs/GSs, the electrical conductivity is further increased to 1.7 × 10−3 S/cm, which can be regarded as conductive materials. The LOI value is reached to 28.6%, with peak heat release and total heat release reduced by 26.4% and 16.4%, respectively.
