Expanded poly(tetrafluoroethylene) membrane surface modification using acetylene/nitrogen plasma treatment

Control of pore structure and characterization of plasma-polymerized SiOCH films deposited from octamethylcyclotetrasiloxane (OMCTS)

“…The plasma deposition was conducted in a custom-built vacuum chamber, which was described in our previous study [12]. OMCTS was volatilized in a heating jacket at 40 • C and delivered to the plasma reactor by a powered showerhead assembly through a vapor mass flow controller (MKS type 1150).…”

Surface modification of porous poly(tetrafluoraethylene) film by a simple chemical oxidation treatment

“…Since poly(tetrafluoroethylene) (PTFE) has many favorable qualities, such as excellent chemical resistance, good thermal stability, low surface energy, low frictional coefficient and low dielectric constant [1][2][3][4][5][6], it plays a crucial role in the plastic industry. These properties are very important for special applications, such as low friction films, seals and biomedical devices, etc.…”

Chitosan coagulation–membrane filtration of Chlorella vulgaris

“…The turbidities of collected samples were measured. The PFTE membrane was made according to procedures by Tu et al [28] and Huang et al [29]. The resulted membrane has a mean pore size of 0.91 mm and contact angle of 60 .…”
