Method used

Columnar model is shown in Figure 2, and 10mL plastic tube is taken as mold (Figure 2 (a)), and the precursor solution prepared before adding (i.e. system before initiation) is cross-linked by thermal initiation system to obtain columnar ion Liquid gel (Fig. 2(b)), apply an appropriate amount of copper chloride crystals on the surface, cut the gel into 4 parts with a razor blade (Fig. 2(c)), and then splicing the 4 parts of the gel randomly (different segments Copper chloride crystals were applied in different amounts to distinguish different sections in appearance), and placed for 5s (Fig. 2(d)). The bridge load model is shown in Figure 3. The spliced ​​gel is suspended in the air, and it can be seen that the gel can still mai...

Abstract

A preparation method of high-transmittance self-healing ionic liquid gel with good mechanical properties comprises: adding a monomer and a photoinitiator into ionic liquid, mixing well, removing oxygen, adding to a light-transmitting container, and exposing to an ultraviolet lamp to obtain the ionic liquid gel; or comprises: adding a monomer and a thermal initiator into ionic liquid, mixing well, removing oxygen, adding to a mold, mixing well under stirring, and curing to obtain ionic liquid gel. By modifying ionic liquid gel synthetic process parameters, such as the monomer for reaction, molar ratio of the monomer, reaction time, and initiating mode, self-healing property can be introduced to the field of ionic liquid gels successfully, and certain stress tolerance is imparted; the mechanical properties of the gel are significantly improved, the yellowing problem common in ionic gels is solved, and the gel has good light transmittance; the gel has a promising application prospect in the crossing field of gels.
