Abstract:
(EN) [Problem] To provide a self-supportive organic-inorganic hybrid hydrogel which can be prepared by simple mixing at room temperature. [Solution] The present invention provides: a hydrogel-forming composition capable of forming a self-supportive hydrogel, the hydrogel-forming composition being characterized by comprising colloidal silica particles (A) and a polymer (B) containing a unit structure represented by formula (1) (in the formula, R1 and R2 each independently represent a hydrogen atom or a C1-10 linear, branched, or cyclic alkyl group which may have a substituent, or R1 and R2 may bond with each other to form a ring structure); and a hydrogel prepared from the hydrogel-forming composition.
(FR) La présente invention concerne un hydrogel hybride organique-inorganique autoporteur qui peut être préparé par simple mélange à température ambiante. La présente invention concerne : une composition formant un hydrogel capable de former un hydrogel autoporteur, la composition formant un hydrogel étant caractérisée en ce qu'elle comprend des particules de silice colloïdale (A) et un polymère (B) contenant une structure de motif représentée par la formule (1) (dans la formule, R1 et R2 représentent chacun indépendamment un atome d'hydrogène ou un groupe alkyle en C1-10 linéaire, ramifié ou cyclique qui porter un substituant, ou R1 et R2 peuvent se lier l'un à l'autre pour former une structure cyclique) ; et un hydrogel préparé à partir de la composition formant un hydrogel.
(JA) 【課題】 室温で混合するだけで作製できる自己支持性を有する有機無機複合ヒドロゲルを提供する。 【解決手段】 自己支持性を有するヒドロゲルを形成することができるヒドロゲル形成性組成物であって、式(1): (式中、R1およびR2はそれぞれ独立して水素原子、置換されていてもよい炭素原子数1乃至10の直鎖状、分岐状若しくは環状のアルキル基を表すか、又はR1およびR2は互いに結合して環構造を形成しても良い。)で表される単位構造を含む重合体(B)、及びコロイダルシリカ粒子(A)を含むことを特徴とする、ヒドロゲル形成性組成物、それより作られるヒドロゲルである。
