introduction

Polylactic acid (PLA) is a biodegradable polymer with broad application prospects in packaging, medical and other fields. The preparation of PLA film is crucial to its application performance. Traditional preparation methods are usually limited by complex processes and high costs. Therefore, it is particularly important to seek a simple and efficient preparation method. Thin layer chromatography (TLC), as an analytical technique, has been widely used in the field of material preparation in recent years. This article explores the possibility of applying TLC technology to the preparation of PLA films, and introduces its preparation methods and application prospects.

experimental method:

Prepare the TLC bottom plate and solution: Select the appropriate TLC bottom plate and solution, and select the appropriate solvent system according to the experimental needs.

Solution coating: Coat the PLA solution evenly on the TLC bottom plate, and control the coating thickness and coating area.

Drying: Dry the coated TLC bottom plate in a ventilated place until the solvent has completely evaporated.

Analysis: Use TLC technology to analyze the coated PLA solution to control film thickness and composition.

Defilming: Put the TLC bottom plate into an appropriate solvent and separate from the bottom plate to obtain a PLA film.

Results and discussion

PLA films prepared by TLC technology have better thickness control capabilities and composition control capabilities. By adjusting parameters such as solution concentration and coating speed, we can achieve precise control of the PLA film thickness to meet the needs of different application scenarios. In addition, the PLA film prepared by TLC method has good biocompatibility and degradation properties and is suitable for applications in the biomedical field.

in conclusion

This study proves that TLC technology has good application prospects as a new PLA film preparation method. PLA films prepared by the TLC method have precise thickness control and composition control capabilities, and are suitable for applications in biomedicine, food packaging and other fields. In the future, we will further explore the optimization and application of TLC technology in the preparation of PLA films.
