Splet26. sep. 2024 · The relationship between the concentration of H 2 O 2 in the aqueous samples and the thickness of the channel wall is explained by the diffusion mechanism of plasma species in PDMS. The acidification (i.e. decrease of pH value) and sterilization effect of plasma are also observed in the treated samples. SpletThe PDMS microreactor, as shown in Fig. 2, was designed to bene t from the gas-permeability of PDMS: a thin wall of 50 mm between the gas and the droplet channel allows for fast diﬀusion of H 2 to the liquid droplets with reactant and catalyst. The hydrogenation reaction can only take place when the three phases
