Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si(CH₃)₄. It is the simplest tetraorganosilane. Like all silanes, the TMS framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds use in diverse niche applications.
A filtration membrane and a method for producing the same
This invention provides a filter membrane and its preparation method. The preparation method includes the following steps: placing a porous filter membrane substrate in an environment containing plasma and a precursor, and performing plasma treatment to obtain the filter membrane; wherein the precursor includes at least one selected from hexamethyldisiloxane, perfluorooctyltriethoxysilane, pentane, ethylene, toluene, perfluorohexane, styrene, divinylbenzene, hexamethyldisiloxane, tetramethylsilane, tetraethoxysilane, tetrafluoroethylene, and hexafluoropropylene. The filter membrane obtained by this preparation method can significantly reduce the swelling rate and simultaneously increase the permeation flux in organic solvents, achieving precise molecular weight cutoff.
