Abstract

The invention discloses a spin coater rotor capable of achieving real-time image shooting. According to the spin coater rotor capable of achieving real-time image shooting, a camera is fixed above a base, and the base is driven by a motor to rotate. In this way, even during high-speed revolution, the camera and the base still keep relatively static, behaviors, such as spreading, centrifuging, concentrating and crystallizing of a glue solution, of a carrier sheet fixed on the upper surface of the base can be shot by the camera located above the carrier sheet, and the speed and the intensity of the behaviors can serve as bases for optimizing spin coating parameters such as rotating speed, concentration, temperature, solvent types and solute types, and a way for deeply studying matter characteristics is opened up.

Description

technical field [0001] The invention belongs to the technical field of spin coating, in particular to a rotor of a spin coating instrument capable of real-time image shooting. Background technique [0002] Spin coating is a technology for preparing thin films on slides. Its working principle is to drip glue on the slides, and then use a specific device to rotate the slides at high speed, and use centrifugal force to coat the glue on the slides to form a thin film. The thickness and shape of the glue are related to the viscosity coefficient between the glue and the slide and the rotation speed of the slide. If the glue used is a solution, the rotation of the slide will also accelerate the evaporation of the solvent, eventually forming a solid film on the slide. Therefore, the spin-coating process involves a series of kinetic processes such as the expansion, centrifugation, concentration, and crystallization of the glue on the slide, and these processes are related to the pro...
