Monovalent Copper Antimicrobial Coating Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antimicrobial and antiviral compositions and coatings face issues such as persistent antiviral effects requiring reapplication, high copper compound requirements for effectiveness, slow activation times, oxidation leading to decreased efficacy, and the need for increased particle projection for immediate effects.
Innovation Solution
An antimicrobial/antiviral composition incorporating monovalent copper compound microparticles coated with a dispersant and a hydrophilic compound dispersed in a resin, which increases the polar component contribution to the surface free energy of the coating or resin member, enhancing immediate antiviral effects even at low copper concentrations and preventing particle aggregation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large volume of monovalent copper compound is dispersed to achieve high antiviral effect, then antiviral effectiveness is improved, but coating film strength and adhesion deteriorate
Solution Approach 1:
A dispersant is introduced as an intermediary substance to mediate between the monovalent copper compound microparticles and the resin matrix. The dispersant coats the copper particles, preventing direct interaction that would weaken the coating, while maintaining particle distribution for antiviral activity. This resolves the contradiction by allowing high copper content without sacrificing coating strength.
Solution Approach 2:
The coating forms a composite material system consisting of monovalent copper compound microparticles, dispersant, and resin. This composite structure allows the copper particles to provide antiviral function while the dispersant-resin matrix maintains mechanical integrity, enabling both high antiviral effectiveness and adequate coating strength simultaneously.
2Reliability
If monovalent copper compound microparticles are used for antiviral spray, then antiviral effect is achieved, but particles remain at sprayed site requiring re-spraying after cleaning
Solution Approach 1:
The invention merges the antiviral copper particles with a resin binder to form a coating that adheres to surfaces. This combination ensures the copper particles remain固定在 the sprayed site even after cleaning, eliminating the need for re-spraying while maintaining antiviral effectiveness throughout the coating's service life.
Solution Approach 2:
The resin forms a flexible film matrix that encapsulates and secures the copper particles on the surface. This thin film structure allows the coating to withstand cleaning processes while retaining the copper particles in their functional positions, providing long-lasting antiviral protection.
3Reliability
If platinum particles are fixed on fiber surface for antiviral property, then antiviral effect is achieved, but immediate effect of inactivating viruses is poor
Solution Approach 1:
The invention changes the valence parameter of copper from +2 (copper sulfate) to +1 (monovalent copper compound), which fundamentally alters the mechanism of viral inactivation. Monovalent copper acts more rapidly and directly on viral structures, providing immediate antiviral effect while maintaining sustained reliability, unlike platinum particles that require prolonged contact.
