摘要:
Compositions comprising compounds having an aldohexose moiety, a highly fluorinated moiety, and a nitrogen-containing functional group linking the moieties together are disclosed. The aldohexose-based fluoroadditives are effective in reducing the surface tension of water and are useful in various surfactant applications. Also disclosed are processes for making aldohexose-based fluoroadditives.
摘要:
One aspect of the invention is a method for making a composite material comprising a porous support and a porous nanoweb comprising: (a) providing a porous support; (b) providing a gelling mixture comprising one or more solvent(s) and one or more organogelator(s); (c) applying the gelling mixture to the porous support; (d) inducing said organogelator(s) to form a nanoweb gel; and (e) removing the solvent(s) from the nanoweb gel to provide a dry porous nanoweb coating on said porous support; wherein the one or more solvent(s) is a supercritical fluid. Preferably the supercritical fluid is carbon dioxide. Other embodiments of the invention include a nanoweb composite provided by the method.
摘要:
Partially fluorinated amino acid derivatives are provided that are useful as organogelators and surface treatment materials to provide oil- and water-repellency properties to substrates. Also provided are composite materials comprising a porous support and a porous nanoweb. The porous nanoweb contains fibrous structures of about 10 nm to about 1000 nm effective average fiber diameter.
