Abstract: To foster innovative thinking among undergraduates, we have developed a novel experiment focused on the preparation of silicone pressure-sensitive adhesives. Utilizing the silicate method, we synthesized a variety of organosilicon resin structures based on ethyl orthosilicate, which were then combined with 107 glue to create high-performance pressure-sensitive adhesives. This experiment investigates the relationship between structure and performance, integrating polymer materials with practical applications. It aims to enhance students’ understanding of the performance variations in pressure-sensitive adhesives, improve their hands-on skills, and provide them with a profound appreciation of the unique properties and appeal of these materials.
