Preparation method of super-hydrophobic or super-hydrophilic nanofiber membrane with antibacterial performance

Abstract

The invention discloses a preparation method of a super-hydrophobic or super-hydrophilic nanofiber membrane with antibacterial performance. The preparation method of the super-hydrophobic or super-hydrophilic nanofiber membrane with the antibacterial performance is characterized by comprising preparation steps as follows: step (1), a polymer solution is prepared; step (2), electrostatic spinning is performed; step (3), a quaternary ammonium salt solution is prepared; step (4), a suspension mixed liquid containing a quaternary ammonium salt and nano-particles is prepared; step (5), a porous nano-fiber membrane is modified with the suspension mixed liquid containing the quaternary ammonium salt and the nano-particles; step (6), the porous nano-fiber membrane modified with the suspension mixed liquid containing the quaternary ammonium salt and the nano-particles is placed in a vacuum oven at the temperature of 60 DEG C to be dried for 1-3 h, and a finished product of the super-hydrophobic or super-hydrophilic nano-fiber membrane with the antibacterial performance is prepared.

AI Technical Summary

Benefits of technology

This patented technology allows for controlled changes on how layers inside a special material can absorb liquids like blood while maintain their original shape without losing them permanently due to modifications made during manufacturing process such as adding extra substances into it through impregnating methods. By changing certain parameters within this material, different types of liquid absorption capabilities may also occur depending upon factors like pH level, ion concentrations, temperature, solvent type used, and other conditions involved. These techniques allow researchers to study various ways to create effective filters from these films.

Problems solved by technology

This patents describes methods that create special types of fibers called microfins (microscopes) made up from tiny particles attached onto their surfaces through strong interactions like Van der Waals forces). These fibers exhibiting specific characteristics make them ideal candidates for various applications including water purification systems, drug delivery devices, sensors, filters, coatings, wound dressings, tissue engineering scaffolds, and medical implants. However, these techniques involve complex processes involving expensive equipment and may lead to negative effects on human health if they were applied incorrectly.
