Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current diamine compounds used in producing functional polymeric materials face a challenge in achieving a balance between mechanical strengths and elongation rates, resulting in poor stretchability that fails to meet industrial needs.
Innovation Solution
A diamine compound represented by Formula (1) with specific structural features, including (chain alkoxy-methylene) phenyl or (hydroxyl-methylene) phenyl groups, is developed, along with a method for its manufacturing, which involves reacting compounds to obtain a diamine compound that undergoes a reduction reaction to enhance its properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional diamine compounds are used to produce functional polymeric materials, then mechanical strength is improved, but elongation rate deteriorates resulting in poor stretchability
Solution Approach 1:
The invention modifies the chemical structure of diamine compounds by introducing specific functional groups (cyclic carboxylate, cyclic carbonate, or cyclic carbamate groups with 3-8 membered rings). This structural parameter change enables the polymer to achieve both high mechanical strength and high elongation rate (>100%), resolving the contradiction between strength and stretchability that plagues conventional diamine compounds.
Solution Approach 2:
The invention creates a composite functional group structure within the diamine compound, combining rigid aromatic rings with flexible cyclic alkoxy/methylene groups. This composite structure allows the polymer to exhibit both the strength characteristics from the rigid portions and the elongation characteristics from the flexible cyclic portions, simultaneously achieving >90 MPa tensile strength and >100% elongation rate.
2Strength
If the mechanical strength of functional polymeric materials is improved, then strength increases, but elongation rate remains unsatisfactory
Solution Approach 1:
The invention changes the molecular parameter by incorporating cyclic groups (3-8 membered rings containing O, N, or C atoms) into the diamine structure. This parameter modification enables the polymer to achieve elongation rates exceeding 100% while maintaining tensile strength above 90 MPa, thereby improving reliability in terms of elongation without sacrificing mechanical strength.
