WebPDMS has a thermal expansion coefficient of 310 μm m −1 ° C −1 and is thermally stable below 150 ° C. (Clarson and Semlyen 1993, Dow Corning Co. 2005, McDonald and Whitesides 2002). The gas permeability of PDMS and the impermeability of PDMS to liquids are also useful characteristics for some chemical applications, especially in ... WebJan 25, 2024 · The polydimethylsiloxane (PDMS) with high CTE (9.3 × 10 –4 °C −1), low glass transition temperature (Tg = − 125 °C) and young’s modulus (2.07 MPa) was selected as polymer layer (Figure SI 1a and b), which will facilitate the expansion and deformation of PDMS under heat. Therefore, a low driving voltage, lightweight and fast response ...

WebDue to the thermal expansion of PDMS (expansion rate of 0.034% °C -1 ) 43, the resistance of FMHE 3 samples increases by 20~30% when the temperature rises from 25 °C to 60 °C (Fig. 2f). As the ... WebApr 7, 2024 · It consists of an elastomer base and a curing agent, acquired from Farnell, UK. The most common mixing ratio for PDMS is 10 parts Sylgard-184 silicone elastomer base to 1 part Sylgard-184 silicone elastomer curing agent . The PDMS polymer solution was prepared by mixing the PDMS monomer and the curing agents (10:1, volume per volume … WebJan 31, 2024 · The coefficient of linear thermal expansion (CTE, or Lin K) for PDMS is, however, known to be higher than most other polymeric materials. Practically speaking, an average silicone fluid will increase its volume nearly 9% after increasing its temperature by 100 °C.
