Description
(1)液体や固体を芯とした粒子から内部の芯を除去あるいは気化することによる中空化工程を必要とせず、簡便に中空粒子を作製することができる。
(2)固体膜となる原材料は気体として供給され気泡の主成分となるため、気液界面に原材料を効率よく供給することができる。
(3)発生する気泡の径、モノマーガス濃度、膜形成の反応時間などを調整することで中空粒子の径や膜厚を制御することができる。
2 気化容器
3 モノマー
4 混合ガス(モノマーガス、供給ガス)
5 送気装置
6 気泡発生手段
7 液体
8 気泡
9 中空粒子
Claims (3)
- 液体中にモノマーを含む気体を吹き込んで気泡を発生させ、前記気泡の気液界面において前記モノマーと前記液体の接触により固体膜を形成させることを特徴とする中空粒子の製造方法。
- 前記液体は界面活性剤を含有する請求項1に記載の中空粒子の製造方法。
- 請求項1または請求項2に記載の方法で製造した中空粒子。
