Description
Technical Field
The invention relates to the field of functional elastomer materials, in particular to the technical field of elastomers with self-repairing function, and specifically relates to an underwater self-adhesion self-repairing transparent ion conductive elastomer and a synthesis method thereof.
Background
The self-adhesive and self-repairing material has wide application prospect in the fields of tissue engineering, flexible electronics, intelligent packaging and environment and energy. However, most materials that are self-adhesive, self-healing in an air environment do not necessarily have the same ability under water. This is because water molecules can plasticize and penetrate into the interior of the polymer network, thereby greatly impairing intermolecular interactions. Thus, it is challenging to build a self-adhering, self-healing material that is insensitive to water.
Existing eutectic solvents are typically composed of inexpensive and safe hydrogen bond donors and acceptors that can associate through hydrogen bond interactions to form a eutectic mixture. The use of eutectic solvents for the preparation of functional materials is undoubtedly green, low cost and promising, but to date most reported eutectic solvents are hydrophilic. According to the existing report, when the water content in the hydrophilic eutectic solvent exceeds a certain threshold, the eutectic property thereof is lost. Therefore, the material prepared using the hydrophilic eutectic solvent is also very susceptible to external water molecules or environmental humidity changes, so that the overall performance thereof is deteriorated, such as the mechanical strength is severely reduced or the original functions are lost, thereby limiting the wide application of the eutectic solvent.
Thus, in contrast, hydrophobic eutectic solvents have many advantages over hydrophilic eutectic solvents in terms of density, viscosity, acidity, polarity, volatility, etc. Even if the hydrophobic eutectic solvent is miscible with water, a distinct two-phase separation interface can still be created, so that the influence of water molecules can be largely avoided. However, the scope of application of hydrophobic eutectic solvents is limited at present, and in particular, it is not known to use hydrophobic eutectic solvents to prepare elastomers having self-adhesion, self-repairing, transparency and ionic conductivity under water within the technical scope of the art, especially in the field of eutectic solvents.
