Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is an urgent need for novel biocidal materials that can efficiently and safely neutralize pathogens such as viruses, bacteria, fungi, protozoa, algae, parasites, and toxic organic agents, while addressing issues of resistance and safety, particularly in healthcare and environmental applications.
Innovation Solution
The development of halogenated adducts of poly(melamine-silicate) with metal oxides, which are prepared by complexing metal oxides with melamine-silicate either before or after polymerization and then halogenating, creating a hybrid biocide with synergistic antimicrobial and oxidizing properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional biocides are used for disinfection, then pathogen neutralization is achieved, but resistance development and safety issues arise
Solution Approach 1:
The patent combines multiple biocidal mechanisms into a single composite material: poly(melamine-silicate) provides structural framework and binding capacity, metal oxides (such as zinc oxide, magnesium oxide, calcium oxide) contribute antimicrobial properties, and halogenation (chlorine, bromine, iodine) adds oxidizing biocidal activity. This multi-component composite approach creates synergistic effects that enhance pathogen neutralization while reducing resistance development compared to single biocides.
2Productivity
If existing biocidal materials are employed, then disinfection is achieved, but safety risks including cancer and immune disorders increase
Solution Approach 1:
The patent modifies the chemical parameters of traditional biocides by incorporating metal oxides with specific properties (zinc oxide, magnesium oxide, calcium oxide) that have low toxicity and high safety profiles. The halogenation level is controlled to achieve optimal biocidal activity while minimizing harmful byproducts. The poly(melamine-silicate) structure provides controlled release of active components, reducing acute toxicity risks associated with conventional biocides.
3Reliability
If novel biocidal structures are developed, then resistance and safety are improved, but manufacturing complexity increases
Solution Approach 1:
The patent divides the biocidal material into distinct functional segments that can be manufactured separately and then combined: the poly(melamine-silicate) polymer matrix is synthesized first, then metal oxide nanoparticles are incorporated, and finally halogenation is applied. This segmented manufacturing approach allows each component to be optimized and produced using established processes, reducing overall manufacturing complexity despite the advanced composite structure.
