Comparative study of the electrical and structural properties of woven fabrics
چکیده انگلیسی
The application of woven fabrics as the substrate materials for electronic products causes the need to examine their electrical properties at various external effects. This paper presents the results of electrical properties of the fabrics of cotton, cotton/polyethyleneterephtalate (PET) and PET. Dielectric loss factor and dielectric permeability were analyzed in a wide range of temperatures and frequencies. Relaxation peak which appears in this measuring region was identified as the secondary β-relaxation. At different frequencies the dielectric permeability has been analyzed at a different relative humidity at room temperature. At the higher values of relative humidity with the increase of frequency leads to greater reduction of the dielectric permeability and this is more prominent in the samples of cotton and cotton/PET blend. The dc volume resistivity has been investigated in the function of relative humidity at room temperature and interpreted by the raw composition and the structural properties. On the basis of the obtained results, it was concluded that on the electrical properties of cotton/PET blend, cotton has greater impact i.e. the component with the higher dielectric permeability value and smaller dc volume resistivity value.
