“…The key requirement of exploiting the above SMA-related characteristics is, however, a good bonding between the SMA (generally having an oxidized surface) and EP [ 181 , 182 ]. To improve the interfacial adhesion between SMA (wire, foil, band) and EP various strategies were followed such as SMA coupling with reactive (epoxy functionalized) silane [ 183 ], roughening of the SMA surface by physical and chemical methods [ 181 ]. The photoelasticitic feature (birefringence) of adequate EPs may be very helpful to study the adhesion of SMA to EP [ 184 ].…”

Shape memory polymer (SMP) is capable of memorizing one or more temporary shapes and recovering successively to the permanent shape upon various external stimuli. Beside of the above mentioned one-way variants, also two-way shape memory polymers (SMPs) and shape memory (SM) systems exist which feature a reversible shape change on the basis of "on-off switching" of the external stimulus. The preparation, properties and modelling of shape memory epoxy resins (SMEP), SMEP foams and composites have been surveyed in this exhaustive review article. The underlying mechanisms and characteristics of SM were introduced. Emphasis was put to show new strategies on how to tailor the network architecture and morphology of EPs to improve their SM performance. To produce SMEPs novel preparation techniques, such as electrospinning, ink printing, solid-state foaming, were tried. The potential of SMEPs and related systems as multifunctional materials has been underlined. Added functionality may include, among others, self-healing, sensing, actuation, porosity control, recycling. Recent developments in the modelling of SMEPs were also highlighted. Based on the recent developments some open topics were deduced which are merit of investigations in future works.

“…In this respect, electrically conductive adhesives (ECAs) have recently received a lot of attention, on the basis of their importance in basic scientific research and potential industrial applications. Electrically conductive adhesives made from a polymeric matrix (such as, an epoxy, a silicone, or polyimide) that provides adhesion, mechanical strength, impact strength, and metallic filler (such as silver, gold, nickel or copper) that conducts electricity [6][7][8][9][10]. However, the main drawback of these electrically conductive adhesives is the high filler loading to achieve desired conductivity and hence reducing the mechanical properties of the resultant materials.…”

This study is focused on the preparation of electrically conductive nanocomposite adhesives based on epoxy resin or chloroprene rubber containing polyaniline, and multi-walled carbon nanotubes (MWCNTs). For this purpose, MWCNTs were carboxylated (MWCNTs-COOH) by conventional acid oxidation process, and then poly(ethylene glycol) monomethylether was covalently attached to the carboxylated MWCNTs via a esterification reaction. Moreover, carboxylic groups in the MWCNTs-COOH were reduced to alcohol groups (MWCNTs-OH), and then dodecyl-functionalized MWCNTs was synthesized by a substitution nucleophilic reaction in the presence of a solvent composed of 1-bromo dodecane, sodium hydride (NaH), and dry N,N-dimethylformamide (DMF). The functionalized carbon nanotubes (0.5, 1, 1.5, and 2 wt%), and nanopolyaniline (2, 4, 6, 8, and 10 wt%) were added to epoxy resin or chloroprene rubber to produces electrically conductive nanocomposite adhesives.

Shape memory polymers (SMPs) have been the focus of much research over the last few decades. From the novelty of temporarily fixing a threedimensional shape from a planar polymer sheet, to the uses that SMPs are seeing today as softening biomedical implants and self-deploying hinges, this class of smart materials has successfully been used to tackle a variety of biological, electrical, and mechanical problems. However, the properties of these networks are limited by the organic nature of the SMPs. To enhance their properties, researchers across the globe have looked into imparting the desirable properties of inorganic composite materials to these polymer networks. As the field of shape memory polymer composites began to grow, researchers quantified the unique enhancements that came at varying filler loading levels as a result of controlled material interface interactions. Specifically, the incorporation of nanofillers of various shapes and sizes leads to increased internal interfacial area relative to micro-and macrocomposites at identical loading fractions and imparts interesting mechanical, optical, electrical, thermal, and magnetic properties to these emerging nanocomposites. This new class of material, referred to in this review as shape memory polymer-inorganic nanocomposites (SMPINCs), allows a host of new interactions between the smart polymer and its surrounding environment as a result of the ability to control the internal environment of the polymer network and nanofiller. In this work, the reader is introduced to both the methods of preparing these composites and the effects the fillers have on the biological, electromagnetic, and mechanical properties of the resulting composite.
