(ZH) 一种亲水性聚己内酯薄膜的制备方法
Abstract:
(EN) Disclosed in the present invention is a method for preparing a hydrophilic polycaprolactone film, the method comprising: introducing an oxime group to a polycaprolactone pendant group; subjecting a succinic anhydride to esterification with a hydroxyl group in a sideoxime group so as to obtain a carboxylated polycaprolactone; and then reacting a terminal hydroxyl polyethylene glycol with a carboxyl, and grafting the polyethylene glycol to a polycaprolactone side chain so as to obtain a hydrophilic polycaprolactone; and preparing a hydrophilic polycaprolactone film by using solution coating. According to the present invention, the interior of a hydrophilically-modified polycaprolactone material body is also changed from hydrophobic to hydrophilic so as to obtain a modified product having a high grafting rate and a high hydrophilicity. Meanwhile, the preparation method disclosed in the present invention has the advantages of mild reaction conditions, simple preparation processes and strong controllability, and is suitable for industrial production.
(FR) La présente invention concerne un procédé de préparation d'un film de polycaprolactone hydrophile, le procédé comprenant les étapes consistant à : introduire un groupe oxime dans un groupe pendant polycaprolactone ; soumettre un anhydride succinique à une estérification avec un groupe hydroxyle dans un groupe oxime latéral de manière à obtenir une polycaprolactone carboxylée ; puis faire réagir un polyéthylène glycol hydroxy terminal avec un carboxyle, et à greffer le polyéthylène glycol sur une chaîne latérale de polycaprolactone de manière à obtenir une polycaprolactone hydrophile ; et préparer un film de polycaprolactone hydrophile en utilisant un revêtement en solution. Selon la présente invention, l'intérieur d'un corps de matériau à base de polycaprolactone à modification hydrophile passe également du statut hydrophobe à hydrophile, ce qui permet d'obtenir un produit modifié ayant un taux de greffe élevé et un caractère hydrophile élevé. Par ailleurs, le procédé de préparation décrit dans la présente invention présente les avantages de conditions réactionnelles douces, de procédés de préparation simples et d'une forte capacité de contrôle, et est approprié pour la production industrielle.
(ZH) 本发明公开了一种亲水性聚己内酯薄膜的制备方法,先在聚已内酯侧基上引入肟基;再以丁二酸酐与侧肟基中的羟基发生酯化反应,得到羧基化聚己内酯;然后以端羟基聚乙二醇与羧基反应,将聚乙二醇接枝到聚己内酯侧链,得到亲水性聚己内酯;最后采用溶液涂膜制备亲水性聚己内酯薄膜。本发明将亲水改性聚己内酯材料本体内部也由疏水变成亲水,从而得到接枝率很高的改性产物,产品亲水性很高;同时,本发明公开的制备方法反应条件温和、制备工艺简便,可控性强,适合工业化生产。
