OCSiAl, a manufacturer of core components for laser composite machines and printers, has developed a new high-performance conductive polyimide film with graphene nanotubes with a thickness of <100µm.
These advanced films offer an excellent balance of electrical, mechanical, physical, and chemical properties over a wide range of temperatures, extending the potential use of PI films to a broader range of applications.
Offers Conductivity with Anti-Static Properties
The new nanocomposite film demonstrates a surface resistivity of 10
3–10
9 Ohm/sq with a smooth surface and yellow color without black dots. Thanks to a combination of both high manufacturability and cost-effectiveness, the PI-based film enhanced with graphene nanotubes has applications for use in printing systems or other equipment having high friction performance requirements.
“
The presence of graphene nanotubes in an ultralow dosage of 0.1–0.4 wt.% has a significant effect, offering useful properties – from anti-static to conductivity – while preserving key PI characteristics such as resistance to wear, mechanical properties, heat resistance, light weight, and flexibility,” said Zhan Chao, sales manager for polymers, OCSiAl asian division.
“
Thanks to its unique properties, the conductive polyimide film has a potential application where reliable, durable performance is required, including flexible electronics, tapes, labeling, aerospace, and various other high heat applications,” said Dr. Christian Maus, development and support leader for thermoplastics, OCSiAl Group.
