阅读说明：本技术 一种异质结构抑菌剂 (Heterostructure bacteriostatic agent ) 是由 叶勤政 竹内栄治 朱宁 彭开美 谭邵早 熊军 陈新颖 李正锋 方俊山 姚明泽 梁 于 2021-09-29 设计创作，主要内容包括：本发明提供一种异质结构抑菌剂,按质量百分比计算,包括以下原料：聚硅氧烷微球10～30％和水性溶剂30～80％,聚硅氧烷微球包括Cu-(2)O-AO异质结构和聚硅氧烷外壳,Cu-(2)O-AO异质结构被包裹于聚硅氧烷外壳之中,在Cu-(2)O-AO异质结构中,AO表示带隙宽度不低于3eV的n型半导体。本发明利用具有宽带隙的n型半导体与具有窄带隙的Cu-(2)O形成p-n结异质结构,不仅拓宽了宽带隙半导体的波长范围,还提高了材料的光催化性能。利用聚硅氧烷外壳包裹含有Cu-(2)O的异质结构,有效地延缓了Cu-(2)O的氧化。基于上述理由,本发明所提供的抑制结构抑菌剂能够在可见光的激发下,能够对多种有害菌发挥有效的抑制、杀灭作用。(The invention provides a heterostructure bacteriostatic agent which comprises the following raw materials in percentage by mass: 10-30% of polysiloxane microspheres and 30-80% of aqueous solvent, wherein the polysiloxane microspheres comprise Cu 2 O-AO heterostructure and polysiloxane shell, Cu 2 The O-AO heterostructure is encapsulated in a polysiloxane shell in Cu 2 In the O-AO heterostructure, AO represents an n-type semiconductor having a band gap width of not less than 3 eV. The present invention utilizes n-type semiconductor with wide band gap and Cu with narrow band gap 2 O forms a p-n junction heterostructure, which not only widens the wavelength range of the wide band gap semiconductor, but also improves the photocatalytic performance of the material. Wrapping Cu-containing material with a silicone shell 2 O heterostructure effectively postpones Cu 2 And (4) oxidizing O. Based on the above reasons, the bacteriostatic agent with an inhibiting structure provided by the invention can effectively inhibit and kill various harmful bacteria under the excitation of visible light.)
