Wearable flexible electronic strain sensor devices have developed rapidly in recent years due to their potential capacity to detect human motion in various situations. However, it still remains still a big challenge to fabricate strain sensors with high sensitivity over a wide workable strain range. In order to meet this challenge, a new type of strain sensor based on elastomer/carbon nanotube composite fiber is reported in this work. Elastomer fibers are initially prepared via the electrospinning of styrene ethylene butene styrene block copolymer (SEBS). The resultant SEBS fibers are then functionalized by sequentially coating with dopamine (DA) coating and carboxyl group (‐COOH) grafted multi‐walled carbon nanotubes (MWCNTs) under vacuum filtration and ultrasonication. Scanning electron microscopy (SEM) and thermogravimetric analysis reveals that a large amount of MWCNTs is firmly bonded onto the SEBS fibers and evenly distributed. SEBS@PDA/MWCNTs composite fibers based strain sensors exhibit excellent performance, including a high gauge factor of 3717 and large workable strain range up to 530%. Furthermore, the developed sensors demonstrate excellent washing fastness and superior sensitivity in monitoring both small strains (e.g., pulse beats and vocal cord vibrations) and large strains (e.g., finger, elbow, and knee bending).

“…However, its relatively poor tensile strength, limited thermal stability, and nonpolar nature prevent its use from some certain applications. To improve these drawbacks, techniques such as chemical modifications, polymer blending, and incorporation of nanofillers have been reported in some studies . Among these strategies, blending SEBS with other polymers is the most versatile and economical method in industrial settings.…”

In this study, novel polystyrene‐b‐poly(ethylene‐butylene)‐b‐polystyrene (SEBS)/thermoplastic polyurethane (TPU)/organo‐modified montmorillonites (OMMT) nanocomposites were prepared by melt mixing. Three different organo‐modified montmorillonites, DK2, DK3, and DK4 (listed in descending order of hydrophilicity) were selected. The compatibilizing and reinforcing effects of OMMT on the structure, morphology, thermal stability, mechanical and rheological properties of the SEBS/TPU blends were studied. It was found that the hydrophilic DK2 nanoparticles were largely located in the continuous TPU phase and partially dispersed at the phase interphase, whereas DK3 and DK4 nanoparticles were preferentially located at the phase interface with an intercalated/exfoliated and intercalated structure, respectively. Scanning electron microscopy (SEM) results showed that SEBS/TPU/OMMT nanocomposites exhibited a more densely organized and interconnected structure compared with SEBS/TPU blends. Better thermal property was achieved after adding DK3, with the tensile properties of the SEBS/TPU increased considerably. Rheological analysis revealed that hydrophilic DK2 nanoparticles were more effective in improving rheology properties and showed a more pronounced nonlinear effect. The prepared SEBS/TPU/OMMT nanocomposites displayed desired thermal, mechanical and rheological properties, which are important for many applications. POLYM. ENG.

“…Organic modifiers, typically ammonium cations that bear long‐alkyl chains, have been widely used to modify MMT. The metallic cations in MMT can be exchanged with quaternary ammonium or alkyl phosphonium cations, and formation of an organic‐modified MMT (OMMT) with larger inter‐platelet spacing normally leads to optimum properties, especially better mechanical and better barrier properties of the polymer nanocomposite . The inclusion of MMT may also enhance the strength and thermal stability of the char layer formed at the combustion.…”

Summary Polystyrene‐b‐(ethylene‐co‐butylene)‐b‐styrene (SEBS) is a widely used thermoplastic elastomer. However, it suffers from poor flame retardancy. Proper combination of organic‐modified montmorillonite and intumescent flame retardant (IFR) works but is not stable due to easy absorption of moisture. In this study, a novel and stable halogen‐free flame‐retardant system is demonstrated by encapsulating a hydrophobic organophosphate, ie, bisphenol A bis (diphenyl phosphate) (BDP) into a stable micelle and then “attaching” the BDP micelles to the montmorillonite (called: side‐intercalation). The resulted BDP modified montmorillonite (BMMT) has a large inter‐platelet spacing and demonstrated synergistic effect with IFR on flame retardancy, tensile property, and water resistance for the composite with SEBS. In addition to more homogeneous dispersion of IFR and BMMT, a longer‐lasting interfacial interaction between IFR and SEBS matrix with addition of small amount of BMMT also plays the role. The results suggest that BMMT can serve as an effective additive for formulating novel halogen‐free flame retardants for the SEBS to meet increasingly stricter environmental requirements.
