一般描述

活性不透明二氧化钛浆料是具有锐钛矿颗粒和较大尺寸锐钛矿散射颗粒的二氧化钛的前体，用于在氟掺杂二氧化锡玻璃（FTO）基板上形成白色涂层。它被用在多种电化学设备中，以改善电子迁移率和功率效率。

应用

二氧化钛浆料有一种层级化多孔结构，能够以非团聚的形式加载纳米材料，用于制造具有较高光吸收的染料敏化太阳能电池。
在不需要透明度的应用中使用不透明的活性二氧化钛糊剂。
不透明活性二氧化钛糊剂配方中分散的散射颗粒可通过较大的烧结膜表面/体积比，提高DSC性能。
不透明活性二氧化钛糊剂中含有活性锐钛矿颗粒（约20nm）和较大的锐钛矿散射颗粒（可达450nm）的混合物。
干燥后；此糊剂必须在500°C或更高温度下进行烧制。由此形成一层不透明的烧结层，单层的印刷层膜厚为7-8μm，两层约为15μm；当使用48T目时。
该糊剂表现出最佳的流变属性，提供了良好的表面均一性，并含有特别配制的有机粘合剂，以提供适用于一系列染料/电解质系统的通用多孔性。
保存：20°C 避光保存
