In one inventive concept, a product for modifying a cellulose-lignin material with siloxane includes a mixture having a siloxane species, a metal catalyst, and a nonpolar solvent. The mixture is operative to modify a cellulose-lignin material with siloxane upon wetting of the cellulose-lignin material with the mixture and subsequent drying of the cellulose-lignin material. In another inventive concept, a product includes a siloxane-modified cellulose-lignin material having a cellulose-lignin network and a network of siloxane in cross-linking bridges in the cellulose-lignin network.

A nacre-mimetic environmentally friendly composite membrane with an interpenetrating petal structure and a preparation method thereof. Materials for preparing the composite membrane include magadiite, CMC and a bis-silane coupling agent. The composite membrane according to the present invention has an interpenetrating petal stable structure with non-parallel petal-shaped lamellar structure. In addition, inorganic sheets intersperse with each other to form an interlock.

The invention relates to a tyre (100) for vehicle wheels comprising at least one structural element comprising a vulcanized elastomeric material obtained by vulcanizing a vulcanizable elastomeric composition comprising at least one vulcanizable diene elastomeric polymer and at least one composite reinforcing filler, a process for producing a tyre (100) comprising the composite reinforcing filler, a masterbatch comprising the composite reinforcing filler and a process for producing the same, as well as a process for producing the composite reinforcing filler.

A spray dried non-hydrogen bonded (NHB) nano-fibrillated cellulose (NFC) composition and methods for preparing such composition are disclosed. The spray dried NFC with a NHB effect results in low packing density.

The present disclosure provides methods for functionalizing the surfaces of cellulose nanoparticles. In embodiments, nanoparticles are aerosolized, and then passed through a flow reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. In other embodiments, the nanoparticles are aerosolized, and then passed through a plasma reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. Once the functionalized nanoparticles are produced, they may be combined with polymers to form polymer composites having both a polymer and the functionalized nanoparticles. Systems for producing these functionalized nanoparticles, coupled with downstream polymer processing equipment for forming the polymer composites, are also provided.
