Other High-performance Materials
Conductive polymer (PEDOT/PSS)
Overview
PEDOT/PSS is a water-dispersed conductive polymer that forms uniform, transparent conductive films on plastic substrates. Compared with metal-oxide or multi-layer stacks, it offers excellent film-forming ability, optical clarity, and flexibility—balancing appearance, performance, and manufacturing efficiency.
Applications
-
Transparent electrodes and conductive layers for touch panels
-
Anti-static / conductive protective coatings for displays and optoelectronics
-
Functional coatings for PET protective films and flexible packaging
-
Anti-dust, anti-static surface treatment for building and interior materials
Key Advantages
-
Water-based & eco-friendly: low VOC, easy in-line integration
-
High transparency & flexibility: preserves optics and works with flexible substrates
-
Broad substrate compatibility: strong adhesion to PE, PET, PP, PMMA, ABS, PC, nylon, etc.
-
Process-friendly: applicable via screen, gravure, inkjet; one-coat film building
-
Durable & reliable: resistant to heat, humidity, and chemicals for long-term use
Application: High-Performance Anti-Static and Scratch-Resistant Coating Agent with PEDOT/PSS
Positioning
An integrated, single-coat solution for plastics that delivers anti-static (less dust attraction) and scratch resistance (clean appearance and readability), significantly simplifying processes and reducing cost.
Operating Principle | Self-Healing
When minor scratches occur, the film undergoes elastic deformation, storing intermolecular interaction energy (elastic energy). Upon release, this acts as a restoring force, returning the film to its original state and healing shallow scratches, extending service life.
Key Features
-
Dual functions in one layer: anti-static + scratch resistance (replaces two-step stacks)
-
High transparency: maintains optical clarity and display readability
-
Strong adhesion on diverse plastics, reducing substrate constraints
-
Process flexibility: integrates with existing coating/printing equipment
-
Long-term durability under normal use
-
Target uses: wall/floor laminates, PET protective films, flexible packaging, optoelectronic protection layers
Customizable Parameters
Surface resistivity window, transparency/haze, hardness & abrasion class, coating viscosity/solids, drying/curing profiles, etc.
