Embodiment 1

[0056] The preparation process of N-isopropylcyclohexylamine-trifluoroacetic acid supramolecular phase change material: 3mmol N-isopropylcyclohexylamine and 10mL deionized water (or deionized water / methanol volume ratio 1:1, deionized Deionized water / ethanol volume ratio 1:1, deionized water / ethyl acetate volume ratio 1:1, deionized water / acetone volume ratio 1:1) were mixed, and 3 mmol trifluoroacetic acid was added while stirring. The mixed solution was stirred for 10 min, filtered to obtain a clear solution, volatile and grown at normal temperature and pressure, and colorless transparent crystals were obtained after standing for ten days.

Embodiment 2

[0058] The preparation process of N-isopropylcyclohexylamine-trifluoromethanesulfonic acid supramolecular phase change material is as follows: 3mmol N-isopropylcyclohexylamine and 10mL deionized water (or deionized water / methanol volume ratio 1 : 1, deionized water / ethanol volume ratio 1:1, deionized water / ethyl acetate volume ratio 1:1, deionized water / acetone volume ratio 1:1) mix, add 3mmol trifluoromethyl sulfonic acid. The mixed solution was stirred for 10 min, filtered to obtain a clear solution, volatile and grown at normal temperature and pressure, and colorless transparent crystals were obtained after standing for two days.

Embodiment 3

[0060] The preparation process of N-isopropylcyclohexylamine-perchloric acid supramolecular phase change material is: 3mmol N-isopropylcyclohexylamine and 10mL deionized water (or deionized water / methanol volume ratio 1: 1, Deionized water / ethanol volume ratio 1:1, deionized water / ethyl acetate volume ratio 1:1, deionized water / acetone volume ratio 1:1) were mixed, and 3mmol perchloric acid was added while stirring. The mixed solution was stirred for 10 min, filtered to obtain a clear solution, and volatilized and grown at normal temperature and pressure. After standing for a week, colorless transparent crystals were obtained.

Abstract

The invention provides an N-isopropylcyclohexylamine-containing supramolecular phase material, and a preparation method and an application thereof, and relates to a phase change material. The N-isopropylcyclohexylamine-containing supramolecular phase material adopts a chemical formula of [C6H11NH2CH(CH3)2]+M, wherein M is [CF3COO]-, [CF3SO3]- or [ClO4]-. The method comprises the following steps of mixing N-isopropylcyclohexylamine with a solvent, then adding acid and mixing, volatizing and growing the filtered settled solution, and stilling, so as to obtain the N-isopropylcyclohexylamine-containing supramolecular phase material, wherein the acid is one of trifluoroacetic acid, trifluoromethane sulfonic acid and perchloric acid. The phase change material has a series of phase change (including solid-liquid phase change, and solid-solid phase change) along with the change of temperature, and the property along with the change of heat. The N-isopropylcyclohexylamine-containing supramolecular phase material can be applied to the preparation of data storage materials, signal sensing materials, energy storage materials and the like.

Description

technical field [0001] The invention relates to a phase change material, in particular to a supramolecular phase change material containing N-isopropylcyclohexylamine and a preparation method and application thereof. Background technique [0002] Phase change materials are functional materials that can change their physical state (gas, liquid, solid phase) within a certain temperature range. (Wang Xuan, Zhu Jinhua, Liu Mingguang. Research and progress of phase change materials [J]. Guangzhou Chemical Industry, 2013, 41(18): 10-15.) In recent years, phase change materials have been widely used due to their unique structures. It is used in data storage, signal sensing and energy storage and other fields. In terms of energy storage, because phase change materials absorb and release a large amount of latent heat during the process of changing between different phases, the functions of heat storage and release are realized. The main conditions that should be met as a phase chan...
