Composites based on microphase-separated diblock copolymers of styrene with vinylpyridine and gold nanoparticles, in which the block copolymers play simultaneously both the role of a stabilizer preventing the aggregation of nanoparticles and a matrix providing their selective arrangement within domains of the predefined type, are obtained for the first time. The suggested approach implies no use of additional stabilizers and is efficient for both initially organic dispersed small (~5 nm) spheres and hydrasols of larger (9 × 30 nm) rodlike nanoparticles. Nanospheres are introduced into the composites via replacement of a labile stabilizer used in synthesis with the diblock copolymer, while nanorods synthesized in aqueous media by the two-stage method are incorporated via phase transfer mediated by the diblock copolymer. Films capable of microphase separation leading to the formation of vinylpyridine cylindrical domains with a diameter of tens nanometers are spin-coated from the obtained composites. The content of nanoparticles in the composites is up to 5 wt %; they are dispersed and arranged predominantly within vinylpyridine domains, with nanospheres being localized near domain boundaries, while nanorods being mainly oriented perpendicularly to the axis of cylinders.

获得基于苯乙烯与乙烯基吡啶和金纳米颗粒的微相分离的二嵌段共聚物的复合材料，其中嵌段共聚物同时起到防止纳米颗粒聚集的稳定剂的作用和提供其在预定类型的区域内的选择性排列的基质的作用。首次。建议的方法暗示不使用其他稳定剂，并且对于最初的有机分散小球（〜5 nm）和较大的棒状纳米颗粒（9×30 nm）的水溶胶都是有效的。通过用二嵌段共聚物代替用于合成的不稳定的稳定剂将纳米球引入复合材料中，而通过两步法在水介质中合成的纳米棒则通过由二嵌段共聚物介导的相转移而引入。从获得的复合物中旋涂能够微相分离从而形成直径为几十纳米的乙烯基吡啶圆柱域的膜。复合材料中纳米颗粒的含量最高为5 wt％。它们主要在乙烯基吡啶域内分散和排列，纳米球位于域边界附近，而纳米棒主要垂直于圆柱轴取向。
