Poly­(ethylene oxide) (PEO)-based composite electrolyte membranes, which silica (SiO2) and lithium bis­(trifluoromethylsulf)­imide (LiTFSI) were introduced into, were successfully prepared by a self-developed eccentric rotor mixer based on an elongational flow field. Characterization results of electrolyte membranes showed that the eccentric rotor mixer can realize the uniform dispersion of LiTFSI in all electrolyte membranes. This produced a high ionic conductivity of the electrolyte membrane. Among all as-prepared membranes, the ionic conductivity of PEO5 exhibited the highest value of 2.96 × 10–4 S·cm–1 at room temperature due to reaching an extremely uniform dispersion of SiO2. After 90 charge–discharge cycles, the Coulomb efficiency of the LPF/PEO5/Li was still close to 100%, and the discharge specific capacity weakly decreased, revealing an extremely good electrochemical performance of PEO5. Therefore, the eccentric rotor mixer provides an effective strategy for facilitating the development of high-efficiency all-solid-state lithium-ion batteries.

In this work, a novel eccentric rotor mixer (ERM), which can generate circulating volume elongational deformation, is employed to prepare biodegradable polylactic acid (PLA)/poly(𝝐-caprolactone) (PCL) thermo-responsive shape-memory blends without a compatibilizer. The results of scanning electron microscopy (SEM) show that the ERM has more efficient dispersion and compatibilization for blends than conventional Banbury mixers, which is beneficial for shape-memory performance. The results of Fourier transform infrared (FTIR) and differential scanning calorimetry (DSC) also confirm the consequences. Then, morphological and mechanical properties and shape memory behaviors of the blends are investigated in detail. Co-continuous morphology is found on EF-PLA50. The blends exhibit remarkable shape-memory performance. The bending shape fixing ratio and recovery ratio of the blends are more than 94% and are still more than 90% after five shape memory cycles. With the increase of PLA content, the shape fixing ratio of blends decreases, while the shape recovery ratio increases and the shape recovery time becomes shorter. All the blends show good mechanical properties.
