Dielectric Properties of Nanofluids Based on Transformer Oil from the Perspective of Dielectric Relaxation SpeCctroscopy and Temperature Dependencies
摘要
The article focuses on a non-destructive diagnostic method – dielectric relaxation spectroscopy, which is applied to samples of magnetic nanofluids containing fullerenes based on transformer oil, from the perspective of the influence of temperature and predicted long-term thermal degradation. The examined samples were diagnosed in their initial state at various temperatures in this step, and the article discusses the possible assumptions of the physic-chemical mechanisms occurring in the samples due to increased temperature and subsequent thermal degradation.
