dc.descriptionNew compositions of polymer-dispersed thermotropic liquid crystals for moving parts sliding against metals. Properties of the new materials are a function of the concentration and distribution of the liquid crystal in the polymer matrix and depend on the mixing and molding proceses.es
dc.description.abstractComposition and manufacturing processes of blends containing thermoplastic polymers with additives based on ordered fluids such as thermotropic liquid crystals dispersed in the polymer matrix in order to modify the surface and improve the friction and wear resistance of the material and its processability. With this technological offer we try to collaborate with licence agreement and comercial agreement with technical assistance.es

dc.description.ventajasControl of the additive proportion and distribution within a surface layer. This new technology increases the autolubricating ability of the polymers in applications where a high wear and scratch resistance are essential. The liquid crystalline additives can be removed from the matrix by supercritical CO2 extraction, thus allowing complete reciclyng. The new materials are homogeneous with a composition gradient. The new compositions containing thermotropic liquid crystals with controlled distribution and ease of processing allow surface modification with friction and wear reduction without changing the bulk material propertieses
