  • Method of controlling gloss
    Patent number: 8615188
    Abstract: The present teachings provide a fusing method and system of tuning gloss level on a copy substrate. The method includes obtaining an image forming apparatus for forming images on a recording medium including a charge-retentive surface to receive an electrostatic latent image thereon. The method includes applying toner to the charge-retentive surface to develop an electrostatic latent image to form a developed image on the charge-retentive surface. The developed image is transferred from the charge retentive surface to a copy substrate. The toner images are fused to a surface of the copy substrate. The gloss is adjusted on the copy substrate by providing a fuser member having a surface layer a fluoroplastic matrix having dispersed therein aerogel particles wherein the greater a weight percent of the aerogel particles in the fluoroplastic matrix the lower the gloss.

  • DRY COATING PROCESSES FOR SUBSTRATES
    Publication number: 20130260136
    Abstract: Disclosed herein are solvent free, dry coating processes for applying a layered material such as graphene, nanoplate graphite, etc., to a substrate. The applied layered material is devoid of any dispersant and substantially uniform in thickness. Generally, a layered material precursor composition is mixed with a milling medium so that the milling medium is coated with the layered material. The substrate is then contacted with the coated milling medium. The layered material on the milling medium transfers to the substrate to form a coating on the substrate. Such processes may be especially useful for applying conductive films onto a polymeric substrate without the need for additives such as a surfactant or a polymeric binder.
