Temperature-sensitive hydrogel containing adamantyl and preparation method and application thereof

The invention discloses a temperature-sensitive hydrogel containing adamantyl and a preparation method and an application thereof. The preparation method comprises the following steps: adopting organic solvent to dissolve crosslinking agent and monomer which is composed with N-isopropylacrylamide and at least one hydrophobic monomer with adamantyl, then adding initiator to react at 55-85 DEG C for 6-24h under the protection of inert gas, then treating by using distilled water and obtaining the temperature-sensitive hydrogel containing adamantly. The temperature-sensitive hydrogel containing adamantly has excellent properties such as higher mechanical strength and fast deswelling dynamics and easily controllable mechanical strength and temperature response performance, and overcomes the problem that the temperature-sensitive hydrogel provided by the prior art does not have good comprehensive performance. The temperature-sensitive hydrogel containing adamantly can be widely used in fields such as drug delivery, material separation, biosensors, switching valves, reaction control, biomedical material and the like.
