Engineering Contradiction Analysis
1Productivity
If traditional extraction methods (ultrafiltration, enzymolysis, supercritical fluid extraction) are used, then extraction can be performed, but extraction efficiency is low and cost is high
Solution Approach 1:
The patent changes the chemical properties of graphene by introducing amine groups through amination modification. This parameter change transforms graphene into amination graphene with alkaline properties that can selectively adsorb flavonoids through acid-base interactions, thereby improving extraction efficiency while maintaining low cost
Solution Approach 2:
The patent creates a composite material by combining graphene with amine-containing compounds (such as chitosan or organic amines) through surface modification. This composite structure leverages the large surface area of graphene and the alkaline properties of amine groups to achieve efficient and selective flavonoid extraction
2Productivity
If amination graphene is used for adsorption extraction, then separation speed and product purity are improved, but device complexity may increase
Solution Approach 1:
The patent uses amination graphene as a disposable or easily replaceable adsorbent material. The simple adsorption process followed by filtration or centrifugation eliminates the need for complex equipment, achieving fast separation without increasing device complexity
Solution Approach 2:
The patent extracts only the essential functional component (amine groups) and applies it to graphene surface, creating a simple yet effective adsorption system that achieves high separation speed without requiring complex equipment
