Title
(EN) SILICONE-BASED HYBRID POLYMER-COATED ALN FILLER
(FR) CHARGE D'ALN REVÊTUE D'UN POLYMÈRE HYBRIDE À BASE DE SILICONE
(JA) シリコーン系ハイブリッドポリマー被覆AlNフィラー
Abstract
(EN) According to the present invention, a surface-coated AlN filler for obtaining a heat-resistant heat dissipation material that is suppressed in deterioration of characteristics such as thermal conductivity due to hydrolysis of the AlN filler surface is obtained, said heat dissipation material being able to be used in a heat dissipation member that requires high thermal conduction characteristics. A silicone-based hybrid polymer-coated AlN filler according to the present invention is mainly composed of aluminum nitride; and the surface of this filler is coated with a silicone-based hybrid polymer. If 5 g of this filler, which has an average particle diameter of 20-40 μm, is added into 50 mL of an ion exchange water, the electrical conductivity of the water after being held at 121°C under saturated water vapor pressure for 50 hours is 350 μS/cm or less.
(FR) Cette invention concerne une charge d'AlN revêtue en surface permettant d'obtenir un matériau dissipateur de chaleur résistant à la chaleur dont la détérioration des caractéristiques telles que la conductivité thermique due à l'hydrolyse de la surface de la charge d'AlN est éliminée, où ledit matériau dissipateur de chaleur peut être utilisé dans un élément dissipateur de chaleur qui requiert des caractéristiques de conduction thermique élevées. La solution selon l'invention porte sur une charge d'AlN revêtue d'un polymère hybride à base de silicone qui est principalement composée de nitrure d'aluminium ; et où la surface de la charge est revêtue d'un polymère hybride à base de silicone. Si 5 g de la charge selon l'invention, qui a un diamètre moyen de particule de 20 à 40 µm, sont ajoutés dans 50 mL d'une eau échangeuse d'ions, la conductivité électrique de l'eau, après maintien à 121 °C sous une pression de vapeur d'eau saturée pendant 50 heures, est de 350 µS/cm ou moins.
