"On Polydimethylsiloxane (PDMS) "

Polydimethylsiloxane, referred to as PDMS, is an important category of silicone compounds. Its unique properties, wide application, and extraordinary value in many fields.

The properties of PDMS are quite specific. It has good thermal stability, can maintain stability in a wide temperature range, can withstand high temperature without deformation and decomposition, which makes it unique in high temperature environment applications. At the same time, PDMS has excellent chemical stability, is inert to most chemical substances, and is not easy to chemically react with acids and bases, ensuring that it can function normally in complex chemical environments. Furthermore, it has low surface energy, smooth surface, and is not easy to adhere to foreign objects, making it easy to clean and maintain. In addition, PDMS also has good flexibility and elasticity, which can be bent and twisted at will like nephrite, without losing its original physical properties.

Due to the above excellent properties, PDMS application scenarios are extremely rich. In the field of microfluidics, with its good flexibility and processability, it can accurately construct microfluidic channels, realize liquid manipulation and analysis at a small scale, and provide an efficient micro-nano platform for biomedical research, chemical analysis, etc. In the field of optics, PDMS is often used to fabricate optical devices such as optical lenses and optical waveguides, which assist in optical signal transmission and processing. In the field of materials science, PDMS is often used as a template or additive to prepare materials with special morphology and properties, such as porous materials, nanocomposites, etc., to expand the application boundaries of materials. In biomedical engineering, PDMS has good biocompatibility and is non-toxic to cells. It can be used to manufacture cell culture chips, biosensors, etc., which brings convenience to life science research and disease diagnosis and treatment.

With its unique properties, polydimethylsiloxane has pioneered in many fields, continuously injecting new vitality into the development of science and technology and the improvement of life. In the future, it is also expected to shine in more emerging fields.
