Printed Electronic Materials
PRINTED ELECTRONICS
Printed electronics encompasses the creation of large-scale, lightweight, and flexible electronic components using printing techniques, seamlessly integrating electronic elements during the printing process. This technique incorporates electronic building blocks directly into printed products. Notable examples include thin-film transistors (TFTs), organic light-emitting diodes (OLEDs), sensors, flexible displays, solar cells, energy harvesters, radio-frequency identification (RFID) tags, batteries, and other energy storage materials. The field of printed electronics is rapidly expanding and finds applications in various sectors, including automotive, consumer electronics, smart infrastructure, packaging, healthcare, and the Internet of Things (IoT).
Our offerings encompass a wide array of printable inks and substrates, serving as foundational components for electronic printed devices.

PRINTABLE INKS
Our range of printable inks possesses specific rheological attributes and can be categorized into three main types: conductors, semiconductors, and dielectric materials. Diverse deposition methods can be employed to shape these colloidal ink solutions, yielding structures with desired thickness and resolution through techniques such as inkjet printing, screen printing, gravure printing, slot-die printing, and aerosol jet printing, among others. Each approach necessitates precise adjustments of ink parameters, including viscosity, surface tension, conductivity, and compatibility with underlying materials, to ensure consistent and reliable printing processes.
- Conductive Inks
Fundamental to all printed electronic devices, our conductive inks serve as the cornerstone, establishing the essential device structure and interconnects for integrated circuits. Our offerings include inks containing metal nanoparticles and microparticles suitable for various printing methods:
Silver (Ag) inks with commendable physical properties and electrical conductivity
Gold (Au), platinum (Pt), copper (Cu), and nickel (Ni) inks, well-suited for electrochemical sensors, batteries, and fuel cells
Conductive polymer inks, both flexible and biocompatible, crucial for bioelectronics applications
Highly characterized carbon nanomaterial inks, boasting substantial surface area, minimal defects, remarkable chemical stability, and mechanical flexibility, making them particularly appealing for electrode materials in printed batteries, supercapacitors, stretchable bioelectronics, and wearable sensors
- Semiconductor Inks
The heart of printed electronic devices, semiconductor inks play a pivotal role in determining overall device performance. Our extensive selection comprises conventional organic and inorganic semiconductor inks, as well as cutting-edge two-dimensional material inks:
Inorganic metal oxide and organic semiconductor inks offer consistent properties such as mobility and bandgap, delivering reliable performance for printed Organic Light Emitting Diodes (OLEDs), Field Effect Transistors (FETs), and Organic Solar Cells (OSCs)
Emerging 2D nanomaterial inks present benefits like direct bandgap, minimal defects, ease of fabrication, and the potential for novel vertically-integrated electronic devices of the next generation
- Dielectric Inks
Dielectric inks and coatings assume a crucial role in safeguarding and enhancing the functionality of conductive materials. They are integral to energy storage devices and facilitate the operation of electronic components under bias voltage. Our dielectric inks consist of organic polymers or ceramics suspended in solvents, along with innovative insulating 2D nanomaterials like hexagonal boron nitride. These materials contribute to temperature and electrochemical stability, critical for solid-state batteries, field effect transistors, and neuromorphic devices.
SUBSTRATES
Selecting an appropriate substrate entails considering factors like operating temperature range, surface roughness, mechanical properties, transparency, and wettability. Surface treatment using suitable chemicals often enhances ink-substrate compatibility. We offer a variety of conducting substrates coated with materials like Indium Tin Oxide (ITO) or Fluorine-doped Tin Oxide (FTO) on either glass or flexible plastics. These substrates are available in different thicknesses and surface resistivities to cater to various needs.
