FTIR spectra of Laponite, GO, and dry hydrogels were conducted through an IR spectrophotometer (Alpha, Bruker) with the range of wavenumbers from 400 to 4000 cm−1. The morphologies of the hydrogels were observed via field scanning electron microscopy (FESEM, Hitachi S-4800) at an accelerating voltage of 5 kV. Freeze-dried hydrogels were carried out through a SCIENTZ-10N before SEM characterization. The structure of Laponite was characterized by using high-resolution transmission electron microscopy (HRTEM, JEOL-2010) operated at an accelerating voltage of 200 kV. Microscope images of hydrogels colored with a dye of fast green FCF (purchased from Aladdin Industrial Corporation, China) were taken by fluorescence microscope (Eclipse Lv100npol, Nikon). Storage modulus and loss modulus of hydrogels were measured by rheometer (HAAKE RheoStress 6000, Thermo Fisher Scientific). Thermal mapping images of CNT film, hydrogels, and supercapacitors were taken by a thermal infrared instrument (PI 450, Optris). The electrochemical measurements were recorded using an electrochemical systems (CHI 760E, Shanghai Chenhua). The mechanical flexibility and stretchability of hydrogels and supercapacitors were evaluated by fixing them in a mechanical test machine (HY-0350, Shanghai Hengyi Co. Ltd) and recording their electrochemical performance under a given bending state or tensile strain.

Polarizing microscope (ECLIPSE LV100N POL, Nikon, Tokyo, Japan) and fluorescence microscope (CX23, OLYMPUS, Wuhan, China) were used to image microcapsules.
A thermal analysis test with a working temperature range of 50–600 °C was conducted. TGA/DSC simultaneous thermal analyzer (STA449c/3/G, Berlin, Germany ) was used in this paper. The heating rate was controlled at 10 °C/min with a maximum temperature of 600 °C. At the same time, high-purity nitrogen ambient gas was applied at a flow rate of 500 mL/min. During the pyrolysis process, the organic volatile substances of the polymers were decomposed to low molecular weight products. The relationship between the mass of the test sample and the temperature can be obtained from the TGA/DSC tests, which can be used to analysis the rejuvenator content in the microcapsules as well as the thermal stability of the microcapsules.
The FT-IR test can detect functional groups in a material which can be used to determine whether a chemical reaction occurs by comparing the differences in functional groups. The FT-IR test was conducted through an infrared spectrum instrument (Nexus, Thermo Nicolet Corporation, Washington, WA, USA) to confirm the successful synthesis of the microcapsule with wavelengths ranging from 400 cm−1 to 4000 cm−1.

The PDMS freestanding films were prepared by mixing a PDMS base (SYLGARD® 184A, Dow Corning Co.) and a cross‐linker (SYLGARD® 184B, Dow Corning Co.) at a ratio of 10:1 by weight.[45 ] The mixture was poured into a Petri dish and cured for over 24 h at 25 °C. The P1 and P2 thin films were spun cast from the toluene solutions at a concentration of 10 mg mL−1 onto SiO2 substrates passivated with n‐decyltrichlorosilane (n‐DTS, Gelest Inc.). The P1 and P2 thin films before and after the thermal annealing were transferred onto the PDMS substrates at 150 °C in ambient air. Next, the thin films stretched at various tensile strains were mounted onto glass slides, and the OM images of the stretched P1 and P2 thin films were captured using an optical microscope (ECLIPSE LV100N POL, Nikon Inc.) to determine the εc values.

An optical microscope (ECLIPSE LV100N POL, Nikon, Japan) with a digital camera (MC56, MICROSHOT, Singapore) was used to investigate the phase separation kinetics during the membrane precipitation process.38–40 (link)In this experiment, a drop of PSf solution, around 10 μL, was placed on a glass slide and covered with a hydrophilic coverslip as fast as possible to prevent any phase separation of PSf solution in air. The sample was moved to the optical microscope; the magnification was set at 50×. A drop of distilled water was added to the edge of the coverslip, and phase separation occurred when the water came into contact with the PSf solution. The forward velocity of the moving boundary was measured by the optical microscope; images were taken every 5 s. The formula for phase separation kinetics was as shown below: where, De is the diffusion factor (mm2 s−1), X is the phase separation distance (mm), and t is the coagulation time (s).
In this research, the kinetics of membrane formation was studied. The thermodynamic and rheological variation of the PSf solution affected by the addition of PEOX has been discussed.
