| description | The invention provides a preparation method of a quasi-polyrotaxane film and a polyrotaxane film prepared thereof. The preparation method comprises the steps that S1, a polymer containing a polycaprolactone chain segment serves as a guest molecule, pillararene containing an azobenzene group serves as a host molecule, the guest molecule and the host molecule are fully dissolved in an organic solvent at the temperature of 0-50 DEG C according to the molar ratio of 1: (1-1000), and a quasi-polyrotaxane solution is formed; and S2, the quasi-polyrotaxane solution is sprayed at the speed of 0.2-60 mL/h through an injection pump by adopting an electrostatic spraying technology under the conditions that the voltage is 5-40 KV, the receiving distance is 5-30 cm and the humidity is 50% RH to 90% RH, so as to obtain the quasi-polyrotaxane film. According to the method, raw materials are easy to obtain, the cost is low, operation is easy, the requirement for equipment is low, and repeated writing and erasing of informati |
