An example of our specialty porous materials is shown in the image above. The scanning
electron microscope image is of a porous, mixed metal oxide film with a very narrow pore size distribution with pore size of
approximately 300 nanometers. The electrical properties and film thickness (which is less than 2 microns) of this film were
developed to meet the unique requirements of our customer. To meet their purity requirements, production is undertaken in one
of our Class 100 cleanrooms.
also develops and markets high performance porous adsorbents for specialty applications. With our knowledge and expertise of
porous material and surface modification, we tailor the properties of both silica and carbon-based adsorbents to achieve
superior adsorption performance in applications such as gas masks, ammonia/amine removal in IC Fabs, and high temperature
acid gas cleanup.
Improvements we have made to adsorbents include an increase in total uptake, an increase in uptake/retention at very low
concentrations, and lowering poisoning by adsorption of secondary adsorbates. Another benefit is modifying the kinetics
in order to reduce cycle time in applications such as PSA (Pressure Swing Adsorption) columns.
A typical example is shown below. In this case, NanoPore has surface modified commercial activated carbon in an effort to
improve ammonia adsorption capacity. This is a preliminary result which shows approximately a 10x improvement in capacity
over the starting activated carbon and 2-3x over a commerical carbon which has been impregnated for ammonia adsorption.
Newer samples have capacity 2-4x higher than the sample shown below. These surface-modified carbons are in development and
are being offered in developmental quantities to key customers.
