  • PROCESS FOR MANUFACTURING A MULTILAYER MEMBRANE ON A SOLID SUPPORT USING AN AMPHIPHILIC BLOCK COPOLYMER
    Publication number: 20200030750
    Abstract: Disclosed is a process for manufacturing a membrane from a, amphiphilic block copolymer including a hydrophilic block and a hydrophobic block including functions capable of forming a bond with the hydrophilic block in a bath containing the copolymer in solution in an apolar organic solvent, for a sufficient time to enable the formation of non-covalent bonds between the hydrophilic block and the support and the immobilisation of a first layer of the copolymer on the surface of the support; followed by adding water to the bath, so as to give rise to the self-assembly of a second layer of copolymer on the first layer.

    Assignees: UNIVERSITE DE BORDEAUX, INSTITUT POLYTECHNIQUE DE BORDEAUX
    Inventors: Sébastien Lecommandoux, Jean-François Le Meins, Christophe Schatz, Kamal Kumar Upadhyay
  • Perfuming compositions and uses thereof
    Patent number: 9000052
    Abstract: A perfuming composition capable of prolonging the release of a perfuming component into the surrounding environment when applied on a surface. This composition utilizes hydrophobic block copolymers in the presence of high amounts of ethanol. The invention also relates to consumer articles containing such compositions. It finally provides methods for the perfuming of a surface and a method for increasing the long-lastingness of a perfuming component using these compositions.
