Canatu has developed a new component manufacturing method called Direct Dry Printing (DDP) which allows direct synthesis and patterned deposition of NanoBud® films on any substrate material even at room temperature. Canatu patented innovations remove all of the existing bottlenecks to the commercialization of carbon nanotechnology.
The combination of Canatu’s unique patented synthesis method, which produces clean, unbundled, high crystallinity Carbon NanoBuds directly in the gas phase, and Canatu’s efficient Direct Dry Printing method, which allows homogenous or patterned deposition on any substrate at room temperature and pressure, results in a simple, scalable, one-step, low cost component manufacturing process.
Canatu’s Direct Dry Printing is applicaple to both sheet feed and Roll-to-Roll implementations. This, combined with traditional screen, gravier and flexo allows Canatu to produce continuous rolls of complex, multi-layered components.
Unlike traditional batch methods which start with nanotube powders and require multiple, complex and expensive processing steps to achive deposites, Canatu’s methods start with better material and maintains these material qualities on the substrate. No material degrading, hazardous, acid treatments, sonification, surfactants or functionalizations are required. With this method, a wide variety of high performance components can be easily produced in a more rapid, economical and environmentally sound proceedure.
Canatu’s manufacturing method is simpler, and hence, less costly than competing techniques, drastically reducing the number of steps to make deposits and increasing the quality and performance of the final products. Since Canatu’s raw materials are just carbon and iron and the manufacturing process operates at atmospheric pressure, production costs are low. Moreover, waste products from other industrial processes, such as CO, methane and alcohols, can be recycled to produce Canatu’s carbon nanomaterials and making ours a very environmentally friendly technology.
In traditional methods for synthesizing single-walled carbon nanotubes, precursor materials are introduced in an uncontrolled manner leading to large variations in reaction conditions. This increases the inhomogeneity of product, reduces yields and produces a large fraction of impurities that must then be removed by complicated purification processes using acids, solvents and surfactants to arrive at usable material.
