Solution Overview
Problem
Current polymer development methods lack materials with targeted properties such as high crosslinkability, reactivity, and acid resistance, particularly in polymers with excellent cation transferring ability and proton conductivity.
Innovation Solution
A sulfonate-based compound with a fluorine group and sulfur linking group, represented by Chemical Formula 1, is developed, which includes reactive groups and groups convertible to reactive groups, enabling the formation of polymers with high molecular weight, solubility, and acid resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional polymer materials are used, then basic polymer properties are achieved, but high crosslinkability, reactivity, and acid resistance cannot be obtained simultaneously
Solution Approach 1:
The patent combines multiple functional groups (sulfonate group, fluorine-containing group, and reactive groups) into a single monomer molecule. This merging approach allows the resulting polymer to simultaneously achieve high crosslinkability through the reactive groups, acid resistance through the sulfonate group, and proton conductivity through the fluorine-containing group, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The monomer structure integrates multiple functional components that would traditionally require separate materials or additives. The composite functional structure enables the polymer to exhibit multiple desirable properties (crosslinkability, reactivity, acid resistance, proton conductivity) that cannot be achieved with conventional single-function polymer materials.
2Strength
If polymers with high molecular weight are prepared, then mechanical strength is improved, but solubility and processability deteriorate
Solution Approach 1:
The patent modifies the chemical structure parameters of the monomer by incorporating fluorine-containing groups and sulfonate groups, which significantly alter the polymer's solubility characteristics. These parameter changes enable the polymer to maintain high molecular weight while achieving improved solubility and processability, as the fluorine-containing groups provide steric bulk and the sulfonate groups enhance polarity and interaction with solvents.
3Reliability
If acid resistance is enhanced through sulfur linking groups, then chemical stability is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the complex functional requirements into distinct modular components within the monomer structure: the sulfonate group provides acid resistance, the fluorine-containing group provides proton conductivity, and the reactive groups provide crosslinkability. This segmentation allows each function to be optimized independently while simplifying the overall manufacturing process, as all functions are built into the monomer before polymerization.
