Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If nanocarbon material is blended into polymer material, then electrical conductivity and mechanical strength are improved, but uniform dispersion is difficult due to poor affinity
Solution Approach 1:
The patent modifies the chemical structure of the polymer by introducing a cationic group at the terminal position, changing the electrical charge parameter of the polymer chain. This parameter change enables electrostatic interaction with the nanocarbon material, resolving the affinity problem and achieving uniform dispersion while maintaining mechanical strength enhancement.
Solution Approach 2:
The cationic group acts as an intermediary between the polymer matrix and the nanocarbon material. It mediates the interaction by providing a chemical bridge that enhances compatibility and dispersion of the nanocarbon material within the polymer, solving the affinity issue without compromising the reinforcing effect.
2Reliability
If nanocarbon material is blended into polymer material, then electrical conductivity is improved, but uniform dispersion is difficult due to poor affinity
Solution Approach 1:
By introducing a cationic group at the polymer terminal, the electrical charge parameter is modified, enabling electrostatic attraction to the nanocarbon material. This parameter change ensures both uniform dispersion and effective electrical conductivity enhancement by maximizing the interaction between polymer and nanocarbon material.
Solution Approach 2:
The patent creates a composite system where the polymer with cationic terminal group and nanocarbon material form a synergistic combination. The cationic-modified polymer composite achieves both uniform dispersion and high electrical conductivity by combining the structural benefits of the polymer matrix with the conductive properties of nanocarbon material enhanced by electrostatic interaction.
