Embodiment 1

[0034] (a). Prepare prepolymer in advance: prepare melamine-formaldehyde resin prepolymer;

[0035] (b). Stir and mix 50g graphene, 80g of 1-methyl-3-ethylimidazolium chloride ionic liquid, and 40g of dicyclopentadiene at 25 degrees Celsius at 40 rpm to obtain a mixture, and then in the mixture Add 50g of emulsifier NP-10, and then disperse under the action of ultrasound to obtain an emulsion.

[0036] (c). Add 200g of the emulsion prepared in step (b) into the reaction vessel, slowly add 800g of the prepolymer prepared in step (a) under the condition of sufficient stirring, and raise the temperature to 60°C, keep warm and continue the reaction for 35 minutes. The prepolymer is further polymerized to form a capsule suspension slurry of graphene, ionic liquid, and dicyclopentadiene coated with wall materials. After filtering and drying at 65 degrees Celsius, the rubber-based electronic skin self-repairing special microcapsule material is obtained.

Abstract

The invention relates to the technical field of electronic skin self-repairing materials, in particular to a special micro-capsule material for electronic skin self-repairing and a preparation methodthereof. The preparation method comprises the following steps: (a). preparing a prepolymer in advance; (b) dispersing graphene, an ionic liquid, and dicyclopentadiene under the action of an emulsifierto obtain emulsion; (c). adding the emulsion prepared in step (b) to a reaction vessel, slowly adding the prepolymer prepared in step (a) under the condition of sufficient stirring, raising the temperature to 50 to 80 DEG C, holding and continuously reacting for at least 30 minutes, allowing the prepolymer to be further polymerized to form a capsule suspension slurry with a wall material coated with the graphene, ionic liquid and dicyclopentadiene, filtering and drying to obtain a rubber-based special micro-capsule material for electronic skin self-repairing. The micro-capsule material is mixed in inner and outer rubber base layers when preparing the electronic skin, and once the electronic skin is damaged, the capsule can realize the complete self-repairing function of the electronic skin.

Description

technical field [0001] The invention relates to the technical field of electronic skin self-repairing materials, in particular to a special microcapsule material for electronic skin self-repairing and a preparation method thereof. Background technique [0002] Human skin is an active, sensitive and highly elastic sensory organ that undertakes functions such as body protection, perspiration, temperature regulation, and perception of cold, heat, and pressure. The human somatosensory system can convert external environmental stimuli into electrical pulse signals through the skin's tactile, temperature, pain and other receptors, and transmit them to the nerve center through neural pathways, so that the skin can obtain sensory functions such as touch and pain. Based on the multifunctional biological model of the skin, scientists have carried out research on an emerging discipline - tactile electronics (commonly known as "electronic skin", Electronic skin, E-skin), which is used t...
