Novel micro and nanostructured bioemulsions were created by innovative technologies based on fibrillar cellulose/titanium dioxide/(surfactants mixture: dodecandioyl-diglycine and sucrose diester/ethanol/water, for improved surface properties development with applications in leather industry. The high potential of using cellulose as a material for various applications: in membrane technologies for pollutant absorption, in pharmacy, etc. opens the way to obtaining new added value materials (hybrid micro and nanocomposites). The interaction of surfactants with biopolymers in aqueous medium results in the formation of different association structures. There are various morphologies of biopolymer-surfactant association complexes depending on the molecular structure of the biopolymer and surfactant, on the nature of interaction forces between solvents and surfactant or biopolymer. The innovation consists in the technologies for obtaining novel micro and nanostructured bioemulsions, and the compatibilisation with film forming polymers for leather surface finishing. Fibrillar cellulose/titanium dioxide micro and nanocomposites have been stabilized with surfactants mixture: dodecandioyl-diglycine and sucrose diester in a 1:1 ethanol/water ratio, to increase the uniformity of titanium dioxide shell composites. Micro and nanostructures composites like ?pine cones? developed as a result of biopolymer-surfactants interactions for fibrillar cellulose/titanium dioxide/surfactants mixture couple in ethanol/water system are reported by SEM microscopy and DLS analysis. So, a special class of micro and nanoarchitectures is represented by structures organized as ?pine cones? assemblies. The novel micro and nanocomposites can provide the hybrid film with increased resistance to abrasion, rubbing, water and soiling. Environmentally-friendly supports with smart multifunctional features are obtained for various applications.
