Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Carbon nanotubes have low dispersibility and affinity for other materials, requiring complex preprocessing and increasing manufacturing costs. Additionally, carbon nanohorn aggregates with spherical structures struggle to form effective conductive paths, and mixing materials with different structures increases costs without sufficient improvement in electrical conductivity.
Innovation Solution
The development of a nanocarbon composite material that combines fibrous carbon nanohorn aggregates with spherical carbon nanohorn aggregates, both radially structured, to enhance dispersibility and form numerous contacts within a matrix, thereby improving electrical conductivity, thermal conductivity, and mechanical strength.

Engineering Contradiction Analysis
1Reliability
If carbon nanotubes are used to provide electrical conductivity, then electrical conductivity is improved, but dispersibility deteriorates
Solution Approach 1:
The patent combines carbon nanotubes with carbon nanohorn aggregates to create a composite material that leverages the high aspect ratio and conductivity of nanotubes while utilizing the superior dispersibility of nanohorns. The spherical nanohorn aggregates act as dispersing agents that prevent nanotube aggregation, enabling both high electrical conductivity and good dispersibility to be achieved simultaneously in the matrix material.
2Ease of manufacture
If carbon nanohorn aggregates are used to improve dispersibility, then dispersibility is improved, but electrical conductivity deteriorates
Solution Approach 1:
The patent creates a composite where carbon nanohorn aggregates serve as both dispersing agents and conductive elements. While nanohorns alone have limited conductivity compared to nanotubes, their combination with nanotubes creates a synergistic effect where the nanohorn network provides additional conductive pathways and the overall composite achieves superior electrical conductivity while maintaining excellent dispersibility.
3Ease of manufacture
If carbon nanotubes and carbon nanohorn aggregates are mixed separately to achieve high dispersibility and conductivity, then dispersibility and electrical conductivity are improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the functions of carbon nanotubes and carbon nanohorn aggregates into a single integrated composite material system. Rather than requiring separate mixing and processing steps for each component, the composite structure allows both materials to work together synergistically in a unified manner, simplifying the manufacturing process while maintaining the benefits of high dispersibility and electrical conductivity.
