Making Dreams Come True : Mass Producing Graphene from Plastic?

How to manufacture transparent and conductive carbon nanosheet using PIM-1 polymer solution: (a) Quart substrate is being coated with PIM-1 polymer solution with ladder structure and conducts heating in high temperature to manufacture carbon nanosheet. Without any additional process OSC (organic solar cell) can be made directly on the sheet to manufacture solar cells. (b), (c), (d) show thickness, surface resistivity and transparency of the carbon nanosheet, respectively in relation to the concentration of PIM-1. Also, the new method easily controls the unwanted effects from the electronic and optical characteristics of carbon nanosheet, which is produced when the polymer solution is concentrated. As the high molecule solution concentration gets higher as shown in (Axis X, (b),(c)), the thicker it gets as shown in Figure (b) but, it becomes less resistant as shown in Figure (c), and the current flow better.

Graphene is gaining heated attention, dubbed a “wonder material” with great conductivity, flexibility and durability.

However, graphene is hard to come by due to the fact that its manufacturing process is complicated and mass production not possible. Recently, a domestic research team developed a carbon material without artificial defects commonly found during the production process of graphene while maintaining its original characteristics. The newly developed material can be used as a substitute for graphene in solar cells and semiconductor chips. Further, the developed process is based on the continuous and mass-produced process of carbon fiber, making it much easier for full-scale commercialization. In recognition of the innovative approach, the research was introduced on the cover of Nanoscale, a high impacting peer-reviewed journal in the field of nano science.

The carbon nanosheet can be mass-produced in a simpler process while having high quality since the new process bypasses the steps that are prone to formation of defects such as elimination of the metal substrate or transfer of graphene to another board. The final product is as effective as graphene.
