Dimethyl Polysiloxane, commonly referred to as PDMS, is a member of the silicone family known for its exceptional versatility and stability . It is composed of a repeating unit of -Si(CH3)2-O-, which forms a siloxane backbone with methyl groups attached to the silicon atoms. This structure endows PDMS with remarkable flexibility and chemical inertness .
PDMS is synthesized through the hydrolysis of dimethyldichlorosilan, followed by condensation reactions that yield a high molecular weight polymer . The polymerization process can be controlled to produce PDMS with varying chain lengths, suitable for a range of applications .
This polymer exhibits a wide array of unique properties, such as thermal stability, biocompatibility, non-stick characteristics, and resistance to extreme temperatures. It is also hydrophobic, optically transparent, and has a low glass transition temperature, which contributes to its elasticity .
The applications of PDMS are extensive and span across various industries. In the personal care sector, PDMS is used as an antifoaming agent, skin conditioner, and emollient in products like shampoos, conditioners, and skincare products . In the food industry, it is recognized as a safe additive (E900) for use as an antifoaming agent in cooking oils and processed foods . Additionally, PDMS serves as a lubricant, release agent, and component in various industrial applications, including electrical insulation, mold making, and as a base fluid in hydraulic and heat transfer systems .
PDMS is also utilized in the medical field for its biocompatibility and non-toxic nature, finding use in breast implants, contact lens solutions, and as a component in some pharmaceutical formulations . Its applications extend to microfluidics and soft robotics, where its properties make it an ideal material for creating flexible and functional devices .
