Title
(EN) PROCESSABLE SELF-ORGANIZING NANOPARTICLES
(FR) NANOPARTICULES AUTO-ORGANISATRICES TRAITABLES
Abstract
(EN) A method of forming a composition includes adding together a plurality of particle brush systems wherein each of the particle brush systems includes a particle and a polymer brush including a plurality of polymer chains attached to the particle. The plurality of polymer chains of the polymer brush exhibit two chain conformations as the degree of polymerization of the polymer chains increases so that the polymer brush includes a concentrated polymer brush region with stretched polymer chains and a semi-dilute polymer brush region with relaxed chains that is radially outside of the concentrated polymer brush region. The degree of polymerization of the polymer brush is no less than 10% less than a critical degree of polymerization and no more than 20% greater than the critical degree of polymerization. The critical degree of polymerization is defined as the degree of polymerization required to achieve a transition from the concentrated polymer brush region to the semi-dilute polymer brush region.
(FR) La présente invention concerne un procédé de formation d'une composition consistant à ajouter ensemble une pluralité de systèmes de pinceaux particulaires, chacun des systèmes de pinceaux particulaires comprenant une particule et un pinceau polymère comprenant une pluralité de chaînes polymères fixées à la particule. La pluralité de chaînes polymères du pinceau polymère présente deux conformations de chaînes à mesure que le degré de polymérisation des chaînes polymères augmente de telle sorte que le pinceau polymère comprend une région de pinceau polymère concentrée avec des chaînes polymères étirées et une région de pinceau polymère semi-diluée avec des chaînes détendues qui se trouve radialement en dehors de la région de pinceau polymère concentrée. Le degré de polymérisation du pinceau polymère n'est pas inférieur à 10 % de moins qu'un degré critique de polymérisation et pas supérieur à 20 % de plus qu'un degré critique de polymérisation. Le degré critique de polymérisation est défini comme le degré de polymérisation nécessaire pour atteindre une transition depuis la région de pinceau polymère concentrée à la région de pinceau polymère semi-diluée.
