Title:
ELECTRICALLY ACTIVE ANTIBACTERIAL DENTAL FLOSS AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/008213
Kind Code:
A1
Abstract:
The present application provides electrically active antibacterial dental floss and a preparation method therefor. The electrically active antibacterial dental floss comprises 70-100% a piezoelectric polymer matrix and 0-30% piezoelectric ceramic particles; the material of the piezoelectric polymer matrix is at least one among polyvinylidene fluoride, polyvinylidene fluoride-trifluoroethylene and polyvinylidene fluoride-hexafluoropropylene; and the piezoelectric ceramic particles are at least one among barium titanate, barium strontium titanate, lithium niobate, and potassium sodium niobate. The electrically active antibacterial dental floss provided by the present application can generate a piezoelectric effect during use, residue and tartar can be cleaned, and breeding of bacteria in the teeth can further be inhibited by means of the electrified function of the dental floss, which produces good antibacterial performance.
