Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supramolecular compounds with quadruple hydrogen bonding units (4H-units) often require multiple units per molecule to achieve polymeric properties, leading to high molecular weights and melt viscosities, which limit their processing efficiency and application in coatings, adhesives, and inks.
Innovation Solution
Development of supramolecular compounds with a single 4H-unit per molecule, using apolar low molecular weight compounds with melting points below 45°C, allowing for the formation of polymeric properties such as film-forming and ductility while maintaining low melt viscosity, achieved through reactions with 4H-units or linker molecules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple 4H-units are used per molecule to achieve polymeric properties, then film-forming and ductility are improved, but melt viscosity increases and processing efficiency decreases
Solution Approach 1:
The patent changes the molecular weight parameter and the number of 4H-units per molecule from multiple to single, while adjusting the apolar compound structure to maintain polymeric properties with lower melt viscosity, enabling efficient processing
Solution Approach 2:
The patent creates a composite structure combining a single 4H-unit with specific apolar low molecular weight compounds (melting point below 45°C), achieving a balance between polymeric properties and processability through the synergistic combination of these components
2Strength
If multiple 4H-units are used per molecule to achieve polymeric properties, then film-forming and ductility are improved, but molecular weight increases
Solution Approach 1:
The patent changes the molecular weight parameter by using low molecular weight apolar compounds (80-1500 amu) with a single 4H-unit, achieving polymeric properties through supramolecular assembly rather than high molecular weight covalent structures
3Productivity
If low molecular weight apolar compounds with melting point below 45°C are used, then melt viscosity is reduced and processing is improved, but polymeric properties may be compromised
Solution Approach 1:
The patent uses low molecular weight apolar compounds that are simple and easy to process, sacrificing the need for complex high molecular weight structures while achieving the desired properties through supramolecular interactions of single 4H-units
Solution Approach 2:
The patent creates a composite system where the single 4H-unit compound works synergistically with the apolar low molecular weight compound to achieve both low melt viscosity for processing and polymeric properties for performance
