Janus Photochemical/Photothermal Azobenzene Inverse Opal Actuator with Shape Self-Recovery toward Sophisticated Motion

In this paper, optical images were taken Use a digital camera (Nikon n1406 d7200). POM image is: Obtained from Olympus bx53. Record the reflection spectrum Marine optics Maya 2000 Pro fiber spectrometer was used. SEM images were taken on thermo-4800 high resolution field Emission scanning electron microscope. XPS spectra were determined Thermo Scientific escalab250xi was used. Precise temperature Control is realized by the thermal stage of instec hcs402. Thermodynamic analysis was carried out by differential scanning method Calorimetry at heating / cooling rate of 10 ° C / min (dsc6200) − 1 N2 as a protective atmosphere. The temperature changes are: Measured by fluke tix501 infrared imager. Fourier transform Infrared (FTIR) spectroscopy was performed using attenuation total Reflection FTIR spectra on Bruker equinox 55 a spectrometer. UV − the visible spectrum was obtained on uv-2600. Synsaxs experiments were performed on the 1w2a SAXS beam line Beijing Synchrotron Radiation Facility. Wavelength: 1.54 Å was used. The beam size is 1mm × 2mm, position Adjust the height of the detector to 5 m. Dynamic thermomechanical Analysis was performed on Q800 at 10 to 100 ° C.
