Abstract: A composition comprising a phase separated block copolymer and an inorganic dielectric nanoparticle, wherein the nanoparticle is dispersed in the copolymer and is present primarily in one phase. For example, a Ti0 2 nanocomposite can be created via the in situ formation of Ti0 2 within a silane-grafted OBC. Taking advantage of the phase morphology of the OBC and the differential swelling of the hard and soft segments, due to their inherent crystallinity, enables the selective incorporation of Ti0 2 nanoparticles into the soft segments of the OBC.
Abstract translation: 一种组合物，其包含相分离的嵌段共聚物和无机介电纳米颗粒，其中所述纳米颗粒分散在所述共聚物中并且主要存在于一相中。 例如，可以通过在硅烷接枝的OBC中原位形成TiO 2来产生TiO 2纳米复合材料。 利用OBC的相形态和硬链段和软链段的不同溶胀，由于其固有的结晶度，能够将TiO 2纳米颗粒选择性掺入到OBC的软链段中。
