摘要: Microwave plasma was generated in a glass bottle containing 2–3 Torr of oxygen for treatment polymer surface. A “kitchen microwave oven” and dedicated digestion oven were used as the power source. Poly(dimethylsiloxane) (PDMS) slabs treated by 30 W 30–60 s sealed irreversibly to form microfluidic devices that can sustain solution flow an applied pressure 42 psi without leaking. Experimental set up conditions production homogeneous activate PDMS surface irreversible sealing are described detail. The plasma-treated slab characterized using atomic force microscopy (AFM) attenuated total reflection–Fourier Transform infrared spectroscopy (ATR-FTIR). bears silica characteristics.
