Precision spray coater builds coatings through layer-by-layer self assembly

Marketwire — Nanotrons Corporation launched the SPray Assisted Layer-by-layer Assembly System (SPALAS) for nano-enabled optical coatings on semiconductor, plastic, and glass substrates using layer-by-layer (LbL) self-assembly.

The benchtop tool enables multilayer, ultrathin films designed and assembled at molecular dimensions, with controls for thickness and composition. It reportedly offers shorter processing times than alternative methods and equipment like vacuum or sol-gel based coating.

The automated coating process can be performed in a laboratory or production environment without temperature or pressure control. Its wet chemistry LbL adsorption process is based on chemical or electrostatic interactions between the material building blocks. It sprays coatings onto substrates up to 6” x 10”, and can apply alternative positive- and negative-charge functional groups in solution. It also can simultaneously apply multiple solutions.

Potential applications include solar panel light absorption enhancement, anti-reflection (AR) coating of optical surfaces, infrared (IR) optical coatings, anti-fog coatings, and other nanostructured multi-functional coatings.

Nanotrons Corporation, a wholly owned subsidiary of Agiltron Inc., offers advanced nano-engineering technologies. Other Nanotrons products include silver nanowires and graphene. Learn more at
