Abstract: The present disclosure generally relates to a process for manufacturing a processable dried cellulose nanomaterial using a co-solvent of tert-butyl alcohol (TBA), of which unique physical/chemical properties enable facile modification/derivatization. This present disclosure also relates to materials and process of generating of superhydrophobic surface coating using hydrophobic carboxylic acid modified cellulose nanofibers. Both the processes and the products thereof are within the scope of this disclosure.

Abstract: Electronic textiles and methods of fabrication electronic textiles. Nanoparticles of a conductive material are sprayed along a conductive path into a fabric material so as to penetrate into the fabric. A layer of a second conductor material is coated over the nanoparticles along the conductive path. A layer of an insulator material is coated over the layer of the second conductor material so as to encapsulate the conductive path and form a trace. An electrode configured to contact a subject wearing the fabric material includes a layer of a third conductor material coated over the layer of the second conductor and electrically coupled with the conductive path. An electrical connector is secured to the fabric material and electrically coupled with the conductive path. The nanoparticles are sprayed onto the fabric material using a dual regime spray process implemented with a dual regime spray system.
