Outline of Final Research Achievements

The aggregates of poly (acrylic acid) with base in alcohol can be template for hollow silica nanoparticle. The base species, silica source concentration, pH, heating condition, etc. affect silica shell formation and that contributes to confine water in the hollow interior.

Academic Significance and Societal Importance of the Research Achievements

水を内包した粒子を作ることで，高次目標として発汗量が多くても冷えない蓄熱ウェアの開発を目指す。粒子構造設計に加え，繊維の微構造および繊維上に固定化する粒子の分散状態を制御することで，ナノ空間における水分子運動の制限、粒子外壁（シェル）と水との相互作用が吸収波長を広範囲化し蓄熱効率を上げる。
