Crosslinked Cyclic Molecule Nanostructures for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The isolated nanosheets described in previous patents face issues with degradation due to low inclusion ratios of cyclic molecules and limited space for external substance adsorption or inclusion, as the cyclic molecules can move along the chain molecule and are prone to degradation upon dilution with specific solvents.
Innovation Solution
A nano or microstructural body is created with cyclic molecules crosslinked to each other, where chain molecules are included in a skewered manner, with at least 50% of cyclic molecules crosslinked, and chain molecules have regions without cyclic molecules, enhancing structural stability and space utilization for substance inclusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cyclic molecules are arranged in pseudo-polyrotaxanes with low inclusion ratios, then the synthesis and film formation processes are simple, but the isolated nanosheets are liable to degradation upon dilution with specific solvents
Solution Approach 1:
The patent creates a composite structure where cyclic molecules are crosslinked to form a network that incorporates chain molecules. This composite approach combines the simplicity of pseudo-polyrotaxane formation with the stability of crosslinked networks, resolving the contradiction between ease of manufacture and reliability.
Solution Approach 2:
The patent changes the chemical state of cyclic molecules by introducing crosslinking, which fundamentally alters the structural parameters. This transformation from non-crosslinked to crosslinked cyclic molecules enables the system to maintain stability while preserving the simplicity of the overall synthesis process.
2Ease of manufacture
If cyclic molecules are arranged with chain molecules penetrating cavities in a skewered manner, then pseudo-polyrotaxanes form easily, but the ratio of space available for carrying external substances is low
Solution Approach 1:
The patent creates a porous crosslinked structure where cyclic molecules form a network with interconnected spaces. This porous architecture provides abundant cavities and channels for carrying external substances while maintaining the ease of nanosheet formation through crosslinking.
Solution Approach 2:
The patent transitions from one-dimensional chain molecules penetrating cyclic molecules to a three-dimensional crosslinked network of cyclic molecules. This dimensional expansion creates multiple spaces and pathways for substance inclusion, significantly increasing the quantity of substance that can be carried.
3Reliability
If cyclic molecules are crosslinked to each other, then structural stability increases and degradation is reduced, but the device complexity increases
Solution Approach 1:
The patent segments the crosslinked network into discrete nanosheet units with defined boundaries. This segmentation approach maintains the stability benefits of crosslinking while managing complexity by creating modular, isolated structures that can be handled and applied independently.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The crosslinked structure significantly reduces degradation and increases the ratio of available space for substance inclusion, improving the stability and functionality of the nano or microstructural body.
Implementation Method 1
all or part of the adjacent cyclic molecules in the nano or microstructural body are crosslinked to each other
Implementation Method 2
The inside of a cyclodextrin having a cyclic structure is hydrophobic, and hence the cyclodextrin incorporates a hydrophobic molecule (guest molecule) thereinto in water
