Preparation Methods and Performance Comparison of Common Polymer Films
Abstract
As a crucial component in modern material science and engineering, polymer films are widely applied in various fields such as electronic devices, packaging materials, optical elements, and biomedical products due to their excellent physical, chemical, and mechanical properties. There are numerous preparation methods for polymer films, among which solution casting, spin coating, and hot pressing are the most common. Each method, due to its unique process characteristics and applicable scope, produces films with different properties in terms of thickness uniformity, mechanical strength, optical transparency, and thermal stability. Solution casting is simple and cost-effective, making it suitable for laboratory preparation and large-size film production. Spin coating is widely used in the fabrication of electronic and optical films due to its precise control over film thickness and uniformity. Hot pressing is suitable for rapid film formation of thermoplastic polymers but requires high thermal stability of materials. Different preparation methods significantly influence the structure and properties of the films. Therefore, a systematic performance comparison of these methods is of great significance for guiding rational material selection and process optimization of polymer films. This paper focuses on the common preparation techniques of polymer films, analyzing and comparing them based on their processes and performance indicators, aiming to provide theoretical support and technical reference for the application development and performance improvement of polymer films.
