Abstract: A friction material is discloses for a braking pad comprising a binder comprising a mixture of a phenolic resin or a phenol formaldehyde resin and of a thermoplastic. The total amount of said phenolic resin or phenol formaldehyde resin and of said thermoplastic is between 2 and 60% in volume of said friction material. The ratio in volume between phenolic resin or phenol formaldehyde resin and the thermoplastic is from 20 to 80% in volume. Preferably the thermoplastic has a melting temperature between 120° and 350° C. and comprises a polyamide or a thermoplastic polymer with N—H bond, either in the backbone or in the pendant group. More preferably the thermoplastic material is chosen in the group constituted by PA4, PA6, PA1, PA11, PA12, PA410, PA610, PA66, PA612.

Abstract: A cross-point cell nanoarray comprises a mechanical support substrate, first and second orders of uniformly spaced parallel electrodes separated by an electrically active organic film and orthogonally arranged to form an array of cross-point cells, individually addressable by biasing the respective opposite electrodes, by selecting them among those of the respective orders, over a planar area of the substrate. The active organic resin layer includes a block copolymer of a major component resin and of at least one different minor component resin, configured to promote formation of large-scale ordered nanostructures through phase segregation, due to block incompatibility and self-assembly properties of the blocks. Polymeric bocks of the ordered nanostructures configured to sequester conductive nanoparticles and/or conductive nanoparticle clusters originally dispersed in the component organic resins, subtracting them from the surrounding matrix copolymer.
