A composition of matter is described in which a porous material, such as polydimethylsiloxane (PDMS), is coated with parylene N, C, D, or AF-4 by vapor deposition polymerization while a temperature of the porous material's surface being coated is heated to between 60 C. and 120 C., or 80 C. and 85 C., during deposition. The parylene forms nano roots within the porous material that connect with a conformal surface coating of parylene. In some embodiments, a watertight separation chamber in an integrated microfluidic liquid chromatography device is fabricated by heating tunnels in micro-fabricated PDMS and depositing parylene within the heated tunnels.

A composite material, a high-frequency circuit baseboard made therefrom and a production method thereof. The composite material comprises: a dispersed emulsion of fluoropolymer with a low dielectric loss; a porous, expanded polytetrafluoroethylene film; and a powdery packing. The high-frequency circuit baseboard made from the composite material comprises: several laminated sheets of prepreg made from the composite material, and copper foils pressed over the two properties sides thereof.

The dielectric constant of the high-frequency circuit baseboard and prepreg is isotropic in both X and Y directions. The thickness of the prepreg can be regulated by employing porous ePTFE films with a different thickness, which avoids cracking.
