preparation example Construction

[0027] A method for preparing a host-guest self-healing transparent film, the preparation of the self-healing film includes the following steps:

[0028] Step 1. Mix 45-90 mg of 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride with 27-50 mg of N-N-hydroxysuccinimide to obtain a mixed solution I, and then mix Add 300-350 mg of β-cyclodextrin and 160-200 mg of branched polyetherimide into mixed solution I, and react at room temperature for 12-24 hours to obtain branched polyethyleneimine modified with β-cyclodextrin; mix 100- 185mg 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride was mixed with 30-45mg N-N-hydroxysuccinimide to obtain mixed solution II, and then 80-120mg adamantane was mixed with 160 ~200 mg of polyacrylic acid is added to the mixed solution II, and reacted at room temperature for 12 to 24 hours to obtain polyacrylic acid modified with adamantane.

[0029] Step 2. Immerse the glass sheet, silicon sheet or metal alloy sheet in the acetone sol...

Abstract

The invention discloses a preparation method for a subject-object self-repairing transparent film. The method comprises the following steps: 1) modifying beta cyclodextrin with an amido bond on a branch of branched polyethyleneimine and modifying adamantane with the amido bond on the branch of polyacrylic acid, thereby acquiring the branched polyethyleneimine modified with beta cyclodextrin and the polyacrylic acid modified with adamantine, and 2) repeatedly depositing the branched polyethyleneimine modified with beta cyclodextrin and the polyacrylic acid modified with adamantine in turn on a substrate, thus obtaining the subject-object self-repairing transparent film. The method provided by the invention is simple and effective, the operation is simple and convenient and the required time is short.

Description

technical field [0001] The invention relates to a preparation method of a host-guest self-repairing transparent film, belonging to the technical field of host-guest self-repairing film preparation. Background technique [0002] During the use of materials, local damage and microcracks will inevitably occur, which will affect the normal use of materials and shorten the service life. Self-repair is an important issue. The core of self-repair is energy supply and material supply, imitating the principle of biological damage healing, so that composite materials can self-repair and self-heal internal or external damage, thereby prolonging the service life. According to the repair mechanism of self-healing materials, it can be divided into foreign-aid self-healing materials and intrinsic self-healing materials: foreign-aid self-healing materials rely on the introduction of repair substances encapsulated in capsules and other materials to complete their own repair process; the diff...
