UV-Cured PDMS Substrate Fabrication

Check if the same lab product or an alternative is used in the 5 most similar protocols

The PDMS mixture was prepared using commercially available Sylgard 184 (Dow Corning) with the base: curing agent mass ratio of 10:1. Next, it was admixed with benzophenone (Sigma-Aldrich) at the mass ratio of 1:100 benzophenone: PDMS dissolved in xylene (200 mg/ml, POCH Gliwice), and degassed.
The PDMS substrates were prepared on the 25 mm round coverslip glass using a spin-coating technique, resulting in PDMS films with thickness of ~60 μm. The spinning speed was 500 rpm. Then, a fraction of substrates was exposed to UV light (400 W mercury lamp) for times ranging from 0 to 5 h. The irradiated and non-irradiated substrates were baked for 15 min at 150 °C.

glovebox techniques under an inert atmosphere of argon. NMR spectra
were recorded with an Agilent ProPulse spectrometer (¹H
at 500 MHz, ¹³C at 126 MHz). The spectra are referenced
relative to residual protio solvent resonances. Elemental analyses
were performed at Elemental Microanalysis Ltd., Okehampton, Devon,
UK. Solvents were dried by passage through a commercially available

In the case of air and moisture-sensitive reactions, the glassware was oven dried at 100°C for more than 2 hours before use, when the reactions were performed under an inert atmosphere (nitrogen gas). For thin-layer chromatography (TLC) analysis, Merck pre-coated TLC plates (silica gel 60 GF254 0.25 mm) were used. Products were observed under UV light or stained in 2,4-dinitrophenyl hydrazine or potassium permanganate solutions.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
