Abstract
This disclosure provides a fluorine-containing mixture and a fluorine-containing super-oleophobic microporous membrane using the fluorine-containing mixture as a raw material, as well as preparation methods and applications for the fluorine-containing mixture and the fluorine-containing super-oleophobic microporous membrane. The fluorine-containing mixture of the present disclosure comprises, by weight percentage, the following components: Component A: 50%˜90%; Component B: 3%˜25%; Component C: 0%˜35%; Component D: 0%˜3%; wherein Component A comprises high molecular weight polytetrafluoroethylene homopolymer or copolymer dispersion resin; Component B comprises one or more fluorine-containing alkyl acrylate monomers; Component C comprises one or more fluorine-free acrylates; Component D comprises high temperature free radical initiator. There's no need to add inflammable or explosive lubricating oil, making the process highly safe; and the obtained fluorine-containing super-oleophobic microporous membrane has high waterproof, air-permeable, oil-resistant and washable performance, in line with the needs of a new generation of waterproof and air-permeable protective clothing.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
