The invention relates to a fluorescent siloxane elastomer, to a method for producing same, and to the use. The fluorescent siloxane elastomer contains the following structural elements in the network structure thereof: (I) and (II) or (III), wherein: R1 and R2 are the same or different and mean, independently of each other, a methyl, phenyl, vinyl substituent or an H atom; X means a saturated or unsaturated hydrocarbon group having 2 to 6 C atoms; A is an oxygen, nitrogen, or sulfur atom; R3 is a fluorescent dye substituent from the families of the BODIPY or BODIPY and coumarin or BODIPY and naphthalimide or coumarin and naphthalimide fluorophores. The polysiloxanes according to the invention cause a shift in the emission range out of the UV light or expansion of the emission range into the range of visible light having wavelengths of up to 800 nm, and therefore the polysiloxanes are especially suited for detectors having the maximum efficiency thereof in the range. In the combination of the optical, electrical, mechanical, and thermal properties of the polysiloxanes, the polysiloxanes differ substantially from polysiloxanes according to the prior art. The polysiloxanes form the basis for a material that meets the high requirements for high-voltage devices and can be used in particular for monitoring the aging process of insulating means in high-voltage systems. Partial electrical discharges can be reliably optically detected and localized by means of the polysiloxanes.
该发明涉及一种荧光硅氧烷弹性体,以及其制备方法和用途。该荧光硅氧烷弹性体在其网络结构中包含以下结构元素:(I)和(II)或(III),其中:R1和R2相同或不同,分别表示甲基、苯基、乙烯取代基或氢原子;X表示具有2至6个碳原子的饱和或不饱和碳氢基团;A是氧、氮或硫原子;R3是来自BODIPY或BODIPY和香豆素或BODIPY和萘酰亚胺或香豆素和萘酰亚胺荧光团的荧光染料取代基。根据该发明的聚硅氧烷导致发射范围的转移出紫外光或将发射范围扩展到具有长达800纳米波长的可见光范围,因此该聚硅氧烷特别适用于在该范围内具有最大效率的探测器。在聚硅氧烷的光学、电学、机械和热性能的组合中,聚硅氧烷与先前技术中的聚硅氧烷存在显著差异。聚硅氧烷为满足高压设备的高要求而设计的材料的基础,并且特别适用于监测高压系统中绝缘材料老化过程。通过聚硅氧烷可以可靠地光学检测和定位部分电气放电。
