“…Nitrile butadiene rubber (NBR) has been used as a GPE matrix by Nishi’s group, who studied a blend of styrene butadiene rubber (SBR) and NBR as GPE. They obtained a conductivity of 10 –3 S/cm with a 50/50 wt % composite. − On the other hand, Marwanta et al used NBR with ionic liquid and LiTFSI and obtained an ionic conductivity of 10 –4 S/cm . Nevertheless, because of the unsaturated carbons in their backbone, SBR and NBR can be oxidized at high potentials .…”

Gel polymer electrolytes (GPEs) based on polyacrylonitrile elastomer (HNBR) are investigated for lithium-ion batteries application. This study examines the acrylonitrile content, as well as the solvent used to make the GPE, to understand their impact on lithium solvation. To do so, we propose a three-component system comprising HNBR:solvent:LiTFSI to pinpoint the correct ratio to provide the GPE with competitive conductivity. Infrared spectroscopy is used to shed light on the interactions between nitriles and lithium ions. Spin–lattice relaxation times (T 1) and diffusion coefficients of 7Li and 19F for various HNBR-based GPEs are obtained through PFG-NMR, enabling determination of the transport number of lithium cations (t +) and activation energy (E a). Among the GPEs tested, those composed of propylene carbonate with 2 M LiTFSI and HNBR with an acrylonitrile content of 50% are the most promising, with an ionic conductivity of 2.1 × 10–3 S/cm, D 7Li of 12.0 × 10–8 cm/s, and a t + of 0.42 at room temperature. When this GPE was tested in Li5Ti4O12/LiFePO4 coin cells, a capacity of 135 mAh/g was obtained at a discharge rate of D/5, showing promising results for its use in Li-ion batteries. This study highlights the benefits of high acrylonitrile content in the polymer and a solvent with a moderate donor number to promote interactions between nitriles and Li+.

“…Although the influence of crosslinking on mechanical properties in latex blends has been studied previously,9 little attention has been given to the significant influence that the blend composition and latex particle packing behavior has on crosslinking. To address this issue, an acetoacetoxy‐amine system was chosen to model a two‐component reactive latex blend.…”

Model reactive latices were synthesized by semicontinuous emulsion copolymerization of n-butyl methacrylate and acetoacetoxyethyl methacrylate or dimethylaminoethyl methacrylate. The two functional latices were then blended in various ratios to study the influence of blend composition on crosslinking and mechanical properties of the resulting films. Crosslinking was quantified through swelling measurements. It was found that the crosslink density increased with increasing amounts of acetoacetoxy-functional polymer. In addition, the crosslink density exhibited two maxima, at 30/70 and 70/30 (acetoacetoxy-functional latex/ amino-functional latex) blend compositions. The mechanical properties of the films were quantified by dynamic mechanical analysis (DMA). It was shown that optimal mechanical properties occurred when the particles packed most efficiently at the 30/70 and 70/30 blend compositions.

“…Unfortunately, few researchers have explored the influence of the degree of adhesion between the two polymer phases and the distribution of the high‐ T g particles within the low‐ T g copolymer matrix on the mechanical properties of the latex blend films. The main focus of the publications in this area has been on the relationship between the volume fraction of the high‐ T g particles and the mechanical properties of the latex blend films 3–5…”

“…Thus, research in this area was triggered. Again, most of the previous publications have focused on the volume fraction of the filler particles in the latex blend films,5, 13, 14 although some attention has been paid to the interfacial properties 15–18…”

ABSTRACT:The mechanical properties of films prepared from model high-glass-transition-temperature (T g )/low-T g latex blends were investigated with tensile testing and dynamic mechanical analysis. Polystyrene (PS; carboxylated and noncarboxylated) and poly(n-butyl methacrylate-co-nbutyl acrylate) [P(BMA/BA); noncarboxylated] were used as the model high-T g and low-T g latexes, respectively. Carboxyl groups were incorporated into the PS latex particles to alter their surface properties. It was found that the presence of carboxyl groups on the high-T g latex particles enhanced the Young's moduli and the yield strength of the PS/ P(BMA/BA) latex blend films but did not influence ultimate properties, such as the stress at break and maximum elongation. These phenomena could be explained by the maximum packing density of the PS latex particles, the particleparticle interfacial adhesion, and the formation of a "glassy" interphase. The dynamic mechanical properties of the latex blend films were also investigated in terms of the carboxyl group coverage on the PS latex particles; these results confirmed that the carboxyl groups significantly influenced the modulus through the mechanism of a glassy interphase formation.
