Cellulose nanofibers (CNF), also called nanofibrillated cellulose (NFC), are nanosized cellulose fibrils with a high aspect ratio (length to width ratio). Typical fibril widths are 5–20 nanometers with a wide range of lengths, typically several micrometers .
The borates in cellulose insulation provide added control against mold. Installations have shown that even several months of water saturation and improper installation did not result in mold. [10] It is a common misconception that the mere presence of crude borates in cellulose insulation provides pest control properties to the product.
The CNF was started as part of a National Science Foundation initiative in 1977, and has subsequently been partially supported by several other NSF programs. [1] It currently receives about $20 million each year in federal funding. [2] In 2004 the CNF moved into its current facility, Duffield Hall, supported by $100 million in support from Cornell.
Wet-spray cellulose insulation is similar to loose-fill insulation, but is applied with a small quantity of water to help the cellulose bind to the inside of open wall cavities, and to make the cellulose more resistant to settling. Spray application provides even better protection against air infiltration and improves wall rigidity.
Carbon nanofiber, cylindrical nanostructures with graphene layers; Cellulose nanofibre, a type of nanocellulose; Cytotoxic necrotising factor family, members of which are referred to as CNF followed by a number; Cyanogen fluoride, a cyanide compound with the chemical formula CNF
Sportswear textile with nanofiber membrane inside is based on the modern nanofiber technology where the core of the membrane consists of fibers with a diameter 1000× thinner than human hair. This extremely dense "sieve" with more than 2,5 billion of pores per square centimeter works much more efficiently with vapor removal and brings better ...
