Grolltex

About

Grolltex, Inc., founded in 2014 and based in San Diego, California, specializes in the manufacturing of high-quality single-layer graphene and two-dimensional (2D) materials using advanced chemical vapor deposition (CVD) techniques. As a privately-funded company with 10-50 employees, Grolltex has carved out a distinct niche in the graphene market by focusing on large-area, high-quality monolayer graphene and hexagonal boron nitride (hBN) films on various substrates. The company's technology enables the production of wafer-scale graphene with excellent uniformity and minimal defects—critical requirements for electronics and sensor applications where material quality directly impacts device performance. Grolltex's CVD process achieves precise control over graphene growth parameters including temperature, gas composition, and substrate preparation, resulting in reproducible material properties across production batches. The company offers monolayer graphene transferred onto various substrates including silicon wafers, glass, polymers, and metals, providing customers with ready-to-use materials for device fabrication. Beyond graphene, Grolltex produces hexagonal boron nitride films, an insulating 2D material with applications as a dielectric layer in graphene electronics and as a protective coating. The company has developed transfer technologies that move CVD-grown graphene from growth substrates to target substrates while preserving material quality—a technically challenging process critical for commercial viability. Grolltex serves research institutions and companies developing graphene-based electronics, sensors, and photonic devices where monolayer graphene's unique electronic and optical properties are essential. Application areas include transparent conductive electrodes for displays and solar cells, high-frequency transistors, chemical and biological sensors, and photonics components. The company provides customized graphene products tailored to specific customer requirements including patterned graphene, doped graphene, and graphene on specialized substrates. Grolltex has invested in quality control and characterization capabilities including Raman spectroscopy, atomic force microscopy, and electrical testing to ensure materials meet customer specifications. The company collaborates with researchers and device manufacturers to optimize graphene properties for emerging applications, providing technical support throughout the development process. Grolltex represents the specialized segment of the graphene industry focused on high-quality materials for electronics rather than bulk applications, addressing markets where graphene's unique electronic properties justify premium pricing. As graphene electronics transitions from research to commercialization, companies like Grolltex providing reliable sources of device-quality 2D materials play crucial enabling roles, supplying the building blocks for next-generation electronic, sensing, and photonic technologies that leverage graphene's extraordinary properties.
