The invention discloses a manufacturing method for a
fibrous membrane of an extremely hydrophobic organic
macromolecule chemical compound with an oil-water separation function in the technical field of
fibrous membrane manufacturing. The manufacturing method comprises the following steps: synthetizing a
copolymer with excellent electrostatic spinnability by regulating the compounding ratio of a
monomer and controlling the condition of a
suspension polymerization technology and by adjusting and controlling the compositions of a solution,
processing parameters and the temperature and
humidity conditions of environment, and
spinning a
copolymer solution into the
fibrous membrane with the advantages of uniform and small bore diameters, high
porosity, large flux and extremely hydrophobic and oleophylic properties by using an electrostatic
spinning technique. The obtained fibrous membrane has the advantages that the specific surface area is large, the patterns are large, the stacking structure is proper, and the fibrous membrane is in a three-dimensional bore channel structure. Compared with an existing
polymer-based oil-water separation member, the fibrous membrane has the advantages that the bore channel structure is more reasonable, the separation capacity is stronger, the separation efficiency is higher, the anti-
pollution capacity is stronger, the membrane bores are not easy to block, the oil-water selectivity is stronger, the
mechanical strength is higher, the flexibility and the
temperature resistance are better, the preparation process is shorter, the consumed energy is little, the filtering rate is higher, and the cost is lower, so that the fibrous membrane can better satisfy the requirements of industrial practicality.
