“…Concurrently, the decreased peak intensity in Figure 6(B) with an increase in the percentage of the O‐MWCNTs reveals the lower enthalpy of fusion for the hybrid composites. This phenomenon discloses the slow composite transformation process with an increase in the percentage of the O‐MWCNTs due to improving the miscibility of the O‐MWCNTs with EMA 55 …”

Polymer composites with high dielectric constant and minimal dielectric losses have wide ranging prospects for advanced applications in the flexible electronics and electrical industry. In this study, we used the advantages of carbonaceous hybrid nanofillers to develop a flexible dielectric material. Herein, a set of hybrid nanocomposites were successfully fabricated by incorporating the Ti3C2Tx (MXene) and MWCNTs (multi‐walled carbon nanotubes) hybrid mixture as the conductive moiety into the poly(ethylene‐co‐methyl acrylate) (EMA)/ethylene‐octene co‐polymer (EOC) binary blend as the matrices using solution mixing technique followed by compression molding. As prepared, EMA/EOC/Ti3C2Tx/MWCNTs hybrid composites have been characterized by FTIR (Fourier transform infrared) spectroscopy, XRD (X‐ray diffraction), TGA (thermogravimetric analysis), FESEM (field emission scanning electron microscopy), and DSC (differential scanning calorimetry). We studied the effects of Ti3C2Tx and MWCNTs contents in the hybrid composites on the thermal, dielectric, and electrical properties. Among all the 15 wt% hybrid mixture containing 2 wt% MWCNTs loaded composite has the highest dielectric constant (ℇr = 122.21) and the lowest dissipation loss (tan δ = 0.030) at 100 Hz. The present studies recommend the EMA/EOC/Ti3C2Tx/MWCNTs hybrid composites can be used in smart and flexible electronic storage material.Highlights EMA‐EOC blend composites with hybrid Ti3C2Tx/MWCNTs were processed. 2.5 wt% MWCNTs loaded hybrid composite shows excellent thermal stability. Composite with 2 wt% MWCNTs has ℇ' = 122.21 and tanδ = 0.03 at 100 Hz. 2.5 wt% MWCNTs composite has electrical conductivity of 3.26 × 10−8 Ω−1 m−1. This composite can be used in smart and flexible electronic storage material.

“…The influence of these variables will lead to different final properties. [12] One of the aims of the present work is oriented to the investigation of electrical properties of nanocomposites synthesized by in situ polymerizations, which could be used for many electrical applications or to improve the electrical conductivity of different polymeric matrices that can be processed by conventional techniques, such as melt-blending, using a concentrated master batch of nanoparticles homogeneously dispersed in a polymeric matrix, forming conductive structures.…”

“…The influence of these variables will lead to different final properties. [12] As mentioned, HDPE is a highly resistant material, which has been reinforced by introducing different nanoparticles like MWCNT; however, other properties have risen with the introduction of conductive nanostructures, modifying also the polymer's crystallization and nucleation effects. [13] Kuznetzov and co-workers reported nanocomposites based on HDPE and MWCNT, obtained through different methods (mechanical mixing or by in situ polymerizations) which presented electromagnetic properties.…”

This study reports nanocomposite synthesis based on high-density polyethylene with carbon nanotubes through in situ polymerization by coordination, and the use of an aluminohydride zirconocene/MAO system as a catalyst. Nanocomposites of linear polyethylene exhibit higher molar masses than pure high-density polyethylene synthesized under similar conditions; where multiwalled carbon nanotubes (MWCNTs) acted as nucleating agents, shifting the crystallization temperature to higher values than neat high-density polyethylene. Welldispersed MWCNTs in the HDPE matrices of the obtained nanocomposites are observed by SEM, where most of the nanocomposites showed an improvement in their thermal stability and electric conductivity, besides it is possible to obtain nanocomposites containing up to 41 wt% of nanofiller in the polymeric matrix.The aluminohydride complex n-BuCp 2 ZrH 3 AlH 2 , activated with MAO at Al/Zr ratios of 2000, produced homogeneous HDPE/MWCNT composites under in situ polymerization conditions, at 70 C and 2.9 bar of ethylene pressure, with minimal residual alumina in the HDPE matrix.

Ecofriendly supercapacitors (SCs) are fabricated with graphene electrodes printed on recycled‐plastics and utilized seawater as electrolyte. Those devices produced an energy density and capacitance of 50.4 Wh kg−1 and 250.4 F g−1, respectively. Later, a mixture of Bi─Mg─Fe─O (BMO) oxides is added to the SC electrodes and the capacitance of the devices increased up to 209%. Subsequently, SC electrodes are recovered from used/tested devices and utilized as “seed mats” to grow bean plants. For this purpose, pinto bean seeds are wrapped with recycled SC electrodes and later subjected to a germination treatment together with control seeds. The germination parameters are calculated from the bean plants and found that: 1) 100% of the seeds initially wrapped with the SC electrodes germinated, in contrast, only 88.9% of the control seeds germinated and 2) The bean plants grown with the seed mats has the longest roots/shoots. This occurred because the seed mats have Mg/Fe micronutrients on their surface as well as OH/COOH groups (coming from the seawater), which promote the germination and growth of bean plants. The results of this research demonstrated that SC electrodes coated with BMO can be used as a substrate to promote the growth of bean plants, which is of interest for sustainable agriculture.
