Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite materials often exhibit compromised characteristics due to weak interactions between polymer and additive components, such as reduced strength, conductivity, and solubility, which limits their performance in various applications.
Innovation Solution
A ligand capable of binding to structural entities is used to form a ligand-structural entity complex, which can alter the characteristics of the structural entity, such as increasing strength or conductivity, through covalent or non-covalent bonding, and a Linker Unit is employed to efficiently link structural entities, enhancing the properties of composite materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If polymer and additive components are mixed during preparation of composite material, then the composite material can be formed, but the interaction between components remains weak leading to compromised strength
Solution Approach 1:
The patent introduces a ligand as an intermediary component that binds to both the polymer matrix and the additive (structural entity). This ligand acts as a mediator that creates strong covalent bonds between previously weakly interacting components, thereby improving the strength and reliability of the composite material without requiring fundamental changes to the mixing process.
Solution Approach 2:
The patent creates a multi-component composite system consisting of polymer matrix, additive (structural entity), and ligand. This hierarchical composite structure allows each component to fulfill its specific function while the ligand ensures strong interfacial bonding, resolving the contradiction between maintaining component simplicity and achieving strong interactions.
2Strength
If ligand is used to bind structural entity, then strength and conductivity are improved, but the complexity of material composition increases
Solution Approach 1:
The ligand is designed to perform multiple functions simultaneously: it binds to the structural entity, reinforces the polymer matrix, and enhances both mechanical strength and electrical conductivity. This multi-functionality allows a single additive component to address multiple performance requirements, reducing the need for additional separate additives and thereby limiting the increase in material composition complexity.

AI summary
A type of composite material where the matrix material and additive are held together by covalently or non-covalently bound ligands is described. A particularly useful composite material covered by the present invention is a carbon nanotube-reinforced composite material where the matrix consists of a polymer, covalently attached to a linker, where said linker is non-covalently attached to the carbon nanotube. Methods for the preparation of such composite materials are provided.
