In the world of optoelectronics, material advances are the key to the development of more efficient and sustainable devices. One of these innovative materials is PTAA.

What is PTAA?
PTAA, stands for Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine], is a polymeric semiconductor belonging to the poly(triaryl)amine family. It stands out for its ability to transport holes (positive charge carriers) efficiently and for its ability to block electrons, which makes it an essential component in various optoelectronic applications.
Its molecular structure confers excellent charge mobility and high chemical stability, two essential characteristics for the new generation of high-performance electronic applications.

Features:

• Electronic Mobility: exhibits excellent electronic mobility, making it an ideal material for the manufacture of highly efficient and high-performance organic electronic devices.

• Chemical Stability: its robust molecular structure gives it notable chemical stability, which guarantees the durability and reliability of the devices in which it is used.

• Electronic Protection: its ability to block back-current from exposed cells to non-exposed devices, increases the overall useful lifespan of devices.

• Manufacturing Process Support: compatible with a variety of processing techniques, such as thin film roll-to-roll coating, inkjet printing, and vacuum deposition, making it easy to integrate into different technology platforms.

• Optical Transparency: in optoelectronic device applications, exhibits high optical transparency in the visible range of the spectrum, making it suitable for use in OLED (organic light-emitting diode) and OTFT (organic thin film transistor) devices.

Applications in industry

• Electric Batteries
  PTAA is used in the manufacture of lead-acid batteries, which are widely used in electric vehicles, power backup systems, and industrial applications. These batteries are cost-effective and offer a reliable solution for storing energy.
