Embodiment 1

[0036] A method for preparing an ultra-highly cross-linked layered microporous polymer, comprising the steps of:

[0037] (1) Preparation of flaky molybdenum disulfide: at room temperature, add 15ml of deionized water, 15ml of ethanol, and 2ml of oleic acid into a 50ml beaker in turn, mix well and then slowly add 1.6g of sodium oleate and 1.0g of molybdenum NaCl, 0.9g thiourea, stirred for 5-10min, then ultrasonicated for 30-40min until the solution was completely clarified, adjusted the pH of the above solution to about 1.0 with the prepared 2.0M hydrochloric acid, the solution gradually changed from milky white to dark green, and finally turns black. The solution prepared above was moved into a 50ml polytetrafluoroethylene-lined stainless steel hydrothermal kettle, reacted at 180 degrees Celsius for 24 hours, cooled to room temperature naturally, filtered, washed four times with deionized water and pure ethanol, and the The filtered product was vacuum-dried at 60°C for 8 ho...

Abstract

The invention relates to a preparation method for a hypercrosslinked layered microporous polymer. The preparation method comprises the following steps: firstly, preparing flaky molybdenum disulfide with sodium molybdate and thiourea respectively as a molybdenum source and a sulfur source, then allowing diazonium salt to grow on the flaky molybdenum disulfide through a direct grafting method, and carrying out diazonium salt functionalization so as to form a MoS2-PANI conductive polymer; furtherly, adding a copolymer of organic matter polyvinyl alcohol, vinyl benzyl chloride and divinyl benzene under the action of an azodiisobutyronitrile polymeric initiator so as to obtain a hypercrosslinked longer-chain conductive polymer; and finally, controlling reaction temperature and time, and carrying out Friedel-Crafts reaction under the catalytic action of FeCl3 so as to obtain the layered hypercrosslinked microporous polymer conductive material MoHCPs. Compared with the prior art, the preparation method provided by the invention has the characteristics of simple preparation process and required equipment, significantly decreased reaction temperature, easily available raw materials, easiness in implementation of large-scale production, etc.
