Composite Material Based On Polyamide And Submicronic Mineral Particles
Patent #: 7,105,230
Inventor(s): Dominique Dupuis, Patrice Lacombe and Joël Varlet
Company: Rhodia Chimie
Composite material comprising a matrix based on polyamide and mineral submicron particles has been patented. The polyamide is obtained by polycondensation of a diamine with a dicarboxylic acid. The particles comprise a silica-based core and an at least a discontinuous layer of an oxide, hydroxide or hydrated oxide of zirconium, whose isoelectric point is greater than that of the core. The particles are free of a silane coupling agent.
