Benefits of technology

This patented technical solution involves improving the quality or quantity (quality per unit area) of carbon nanotube (CNT)-based materials that have superior characteristics such as strength, flexibility, durability, etc., compared to traditional methods like adding metal flakes during manufacturing processes. By treating CNT surfaces with specific chemical substances called sulfonate groupings, it becomes easier to mix them together without causing unwanted side reactions between different molecules on their edges. Additionally, this modification makes the resulting material more stable against environmental factors including moisture, heat, light, oxygen, pressure, solvent vapor, electric field, magnetic force, gravity, and others. Overall, these improvements improve the overall effectiveness and efficiency of producing large quantities of highly pure carbon nanoplasmonium tubules (CNTS).

Problems solved by technology

This patented technical problem addressed in this patents relating to improving anti-electrostatically charged (ESC) fibers without losing electrical charge overtime caused by moisten environments during use. Current methods involve coating them with various types of coatings that prevent water from entering these fibers while still allowing charges to pass through. Additionally, current techniques involving modifying existing threads can lead to reduced durability and product quality issues.
