A renewable superhydrophobic-superhydrophilic pattern with a minimum dimension of 50 microm is prepared from octadecyltrimethoxysilane self-assembled monolayer-covered superhydrophobic Al2O3 overlayers on a superhydrophilic TiO2 surface via self-assembly and calcination of boehmite (AlOOH.nH2O) particles. The resulting Al2O3 layer plays dual roles as a superhydrophobic layer and as a UV-blocking layer for the underlying TiO2.
通过对勃姆石（AlOOH·nH₂O）颗粒进行自组装和煅烧，在超亲水的TiO₂表面制备了一种最小尺寸为50微米的可再生超疏水-超亲水图案，该图案由十八烷基三甲氧基硅烷自组装单层覆盖的超疏水Al₂O₃覆盖层构成。所得的Al₂O₃层对下层的TiO₂起到超疏水层和紫外线阻挡层的双重作用。
