Splet21. okt. 2024 · The wettability of poly (dimethylsiloxane) (PDMS) coating on plasma-treated glass was studied at room temperature using polar and non-polar liquids. The wettability was investigated regarding the liquids’ surface tensions (STs), dielectric constants (DCs) and solubility parameters (SPs).

SpletWhat can dissolve PDMS? Among the commonly used solvents, chloroform, ether, and xylene are highly compatible with PDMS. They have a solubility parameter (SP, d) in the range of 7.3–9.5 cal ½ cm-3 / 2.PDMS will absorb these solvents from a microchannel, and the polymer will saturate with the solvent over time. SpletTools Sodium methylsulfinylmethylide (also called NaDMSO or dimsyl sodium) is the sodium salt of the conjugate base of dimethyl sulfoxide. This unusual salt has some uses in organic chemistry as a base and nucleophile . Since the first publication in 1965 by Corey et al., [2] a number of additional uses for this reagent have been identified. [3]
