Embodiment 1
[0051] A method for preparing electrothermochromic liquid crystal fibers by a coaxial microfluidic spinning method, comprising the steps of:
[0052] (1) Preparation of black conductive inner layer injection 1: 0.05g sodium alginate powder, 0.5g glucose powder, 0.15g poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonic acid)( Sinopharm Shanghai Test Company) was dispersed in 10mL water with magnetic stirring for 10min, and prepared into uniform injection 2, wherein the mass fraction of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonic acid) relative to water was 0.015wt%;
[0053] (2) Preparation of electrothermochromic liquid crystal injection 2: add 0.05 g of sodium alginate powder, 0.5 g of glucose powder, and 9 g of red cholesteric liquid crystal (U10-006G-680, Shijiazhuang Chengzhi Yonghua Company) into 10 mL of water Stir magnetically for 10 minutes, and prepare uniform injection 2, wherein the mass fraction of red cholesteric liquid crystal relative to water is 90...
Embodiment 2
[0059] Adjust the red cholesteric liquid crystal of 90wt% in the injection 2 of embodiment 1 to the blue cholesteric liquid crystal (U10-006G-480, Shijiazhuang Chengzhi Yonghua Company) of 80wt%, conductive polymer in the injection 1 The two-dimensional Mxene dispersion is used, wherein the mass fraction of the Mxene dispersion is 0.3 wt %; other preparation steps are the same as in Example 1 to prepare electrothermochromic liquid crystal microfibers.
[0060] The photoelectric performance test (see Table 1) and the water and solvent resistance performance test (see Table 2) of the electrothermochromic liquid crystal fiber prepared above were carried out. As can be seen from the test results: for the electrothermochromic liquid crystal fiber obtained in Comparative Example 1, as the concentration of the cholesteric liquid crystal decreases, the thickness of the liquid crystal layer becomes thinner, and the required electrothermochromic driving voltage increases thereupon .
Embodiment 3
[0062] Adjust the red cholesteric liquid crystal of 90wt% in the injection 2 of embodiment 1 to be adjusted to the yellow cholesteric liquid crystal of 70wt% (U10-006G-580, Shijiazhuang Chengzhi Yonghua Company), and others are prepared according to the same method of embodiment 1 The steps are to prepare electrothermochromic liquid crystal microfibers.
[0063] The photoelectric performance test (see Table 1) and the water and solvent resistance performance test (see Table 2) were carried out on the electrothermochromic liquid crystal fiber prepared above. As can be seen from the test results: for the electrothermochromic liquid crystal fibers obtained in Comparative Example 1, as the concentration of cholesteric liquid crystals continues to decrease, the thickness of the liquid crystal layer also continues to thin, and the required electrothermochromic driving voltage also continues to increase. improve.
