Core‐shell inorganic‐organic hybrid nanocomposites, Ti‐PMMAs are constructed applying the titanium‐oxo cluster (Ti6O4(BrC[CH3]2COO)8(OiPr)8, TiO; iPr = isopropyl) as quasi‐spherical initiator for ATRP (atom‐transfer radical polymerization). Confirmed by UV‐Vis measurements and mechanical test, Ti‐PMMAs inherit the properties of both TiO cluster and polymers and show outstanding UV‐proof performance, high visible light transmittances, and excellent mechanical properties and processabilities. The elasticity and toughness of TiO‐polymer nanocomposites can be further optimized by simply tuning the polymer composites during the ATRP reactions. The admirable processability of the hybrid materials render us the capability to produce uniform nano‐coatings of Ti‐PMMAs and TiO2 with thickness approaching to a challenging length scale, 10 nm.

亚纳米级的钛-氧代簇状聚合物纳米复合材料,用于弹性,透明的抗紫外线薄膜和纳米涂料

核-壳无机-有机杂化纳米复合材料,Ti-PMMA是使用钛-氧簇(Ti 6 O 4(BrC [CH 3 ] 2 COO)8(O i Pr)8,TiO; iPr =异丙基)作为ATRP(原子转移自由基聚合)的准球形引发剂。经过UV-Vis测量和机械测试的证实,Ti-PMMA继承了TiO团簇和聚合物的特性,并显示出出色的防紫外线性能,高可见光透射率以及出色的机械性能和可加工性。可以通过在ATRP反应过程中简单地调节聚合物复合材料来进一步优化TiO聚合物纳米复合材料的弹性和韧性。杂种材料令人赞叹的可加工性使我们能够生产出Ti-PMMA和TiO 2均匀的纳米涂层,厚度接近具有挑战性的长度尺度,即10 nm。
