Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an ionic compound is blended to the pressure-sensitive adhesive or adhesive to impart conductivity, then conductivity is improved, but cross-linking efficiency deteriorates
Solution Approach 1:
A metal cation complexing agent is introduced as an intermediary substance that binds to metal cations in the ionic compound. This intermediary complexation prevents the metal cations from interfering with the cross-linking reaction between the polymer and cross-linking agent, thereby allowing the ionic compound to provide conductivity without sacrificing cross-linking efficiency
Solution Approach 2:
The harmful metal cationic charge is extracted or sequestered by the metal cation complexing agent. By removing the interfering metal cations from the cross-linking environment through complexation, the system allows the ionic compound to function as a conductivity additive without inhibiting the cross-linking reaction
2Reliability
If a large amount of ionic compound is used to ensure conductivity, then conductivity is improved, but cross-linking efficiency deteriorates
Solution Approach 1:
The metal cation complexing agent acts as a mediator that allows large amounts of ionic compound to be present in the system without interfering with cross-linking. The complexing agent binds to metal cations, neutralizing their harmful effect on the curing reaction, thus enabling high conductivity with maintained curing rate
3Device complexity
If a small amount of cross-linking agent is used to reduce cost and complexity, then device complexity is reduced, but cross-linking efficiency deteriorates
Solution Approach 1:
The metal cation complexing agent serves as a mediator that enhances the effectiveness of the cross-linking process. By binding to metal cations that would otherwise inhibit cross-linking, the complexing agent allows a small amount of cross-linking agent to achieve high curing rates that would otherwise require larger amounts
