“…Most of the investigated and produced ECAs are epoxy‐based composites, which follow a curing process to reach permanent adhesion. It can be stated that the field of Hot Melt and Pressure Sensitive electrically conductive adhesives, based on non curing polymers, is still in its beginnings . But the industrial interest on these materials seems to be increasing, according to the attention paid by some companies.…”

The effect of flow on the physical properties of polyurethane/carbon nanotubes nanocomposites: Repercussions on their use as electrically conductive Hot-Melt adhesives

The properties of multiwall carbon nanotubes (MWCNT)/polyurethane (PUR) nanocomposites after being submitted to flow, i.e., in conditions similar to their application as electrically conductive adhesives (ECA), are investigated. A decrease of the elastic modulus is observed after flow is stopped, compatible with a rearrangement of the MWCNT/PUR network during flow. The implications of the viscoelastic results on probe‐tack data are elucidated and a slightly higher energy of adhesion is observed for sheared samples. Dynamic viscoelastic measurements reveal that crystallization of PUR is fastened with MWCNTs, shortening the solidification process for samples submitted to flow or not. Electrical conductivity results show that the 4 wt% MWCNT/PUR nanocomposite can be submitted to flow and give, on cooling to room temperature, values of the electrical conductivity between 10−2 and 10−1 Siemens /m. 2 wt% MWCNT/PUR sample presents a shear induced semiconductor to insulator transition and a temperature‐induced isolator to semiconductor transition. We conclude that MWCNT/PUR nanocomposites are good candidates to develop Hot Melt ECAs, since they display satisfactory viscosity, tack, crystallization (linked to permanent adhesion), and electrical conductivity.

“…[1][2][3] Apart from a number of unquestionable advantages, there are also significant drawbacks of glued structures, such as relatively low durability and fatigue strength, when compared to other joining techniques. [4,5] The best polymer materials for adhesive bonding, with high cohesive performance, are epoxy resin adhesives. [6] The strength properties of adhesive-bonded joints depend on many factors.…”

“…[33][34][35][36][37] In the former, a series of tests under various loads is performed in order to obtain the plot of stress vs. the number of cycles to failure, which is known as the S-N curve or Wohler's curve. [20] Many workers [1][2][3][4][5] have investigated the strength and fatigue performance of the joints used in vehicle structures. These joints are mainly subjected to dynamic loading.…”

This paper presents the results of research undertaken to determine the possibility of improving the fatigue properties of peel-loaded adhesive-bonded joints by the constructional modification of the adherend. Fatigue strength tests were carried out on the electromagnetic inductor at the resonance frequency of the adhesivebonded joint specimens. The tests were carried out on the specimens bonded by means of Bison Epoxy and Epidian 57 epoxy compositions with poly-aluminium chloride hardener. The joined elements were modified by making the chamfer or fillet to enlarge the thickness of the adhesive layer with the aim of reducing the stress concentration in the frontal part of the joint. This modification is the result of a research that confirms the existence of a stress concentration on the short section of the frontal part of an adhesive joint. This phenomenon can lead to the rapid initiation of adhesive joint destruction. The fatigue strength tests revealed a significant improvement in fatigue endurance.

“…Among these materials Ag is used most widely. [9,10] In recent years, more and more researches on carbon materials such as carbon nanotubes, nanocarbon black, and graphene nanosheets [11,12] to be used as conductive fillers have rapidly developed for their low cost, oxidation resistance, and stable performance. But their conductive ability is much lower than that of metals.…”

The epoxy-acrylate (EA) was mixed with Ag-plated graphene (Ag-G), which was used as the conductive filler, to prepare the dual-curable electrical conductive adhesive (ECA). The characterization of Ag-G has been carried out by transmission electron microscope, X-ray diffraction, Raman spectrum, and X-ray photoelectron spectroscopy. Results showed that the Ag-G has been successfully prepared and the relative amount of Ag nanoparticles was 11.25 At%. The mechanical and conductive properties together with thermal stability of ECA have also been investigated. The shear strength reached to 4.67 MPa and the electrical conductivity of ECA reached to 0.41 S/cm when the content of conductive filler was 25 wt%, respectively. This content was regarded as the optimum. And, thermal analysis indicated that ECA exhibited better thermal stability than EA.
