The reason is that the h-pdms cover lower than the gas permeability is due to the pdms cover, this results in gas permeability and induce marangoni instability plays an important role.
The reason is that h-PDMS cover of gas permeability is low than this results in PDMS is a cover gas permeability and Marangoni instability induction in important role.
The reason is that H-PDMS cover of the gas permeability is lower than PDMS cover, and the result of gas permeability and induce Marangoni measures in an important role.
