Abstract
This paper conducts a comparative study on the electret properties of type I collagen in the lungs of normal rats and experimental silicosis rats. Rat lung type I collagen can generate a thermally stimulated depolarization current (TSDC) with space charge properties without being polarized by an electric field. ), indicating that it has natural electret properties. The TSDC experiment of electric field polarization shows that lung collagen has very significant polarization properties. The peak temperature of TSDC of silicosis lung collagen is higher than that of normal lung collagen, and the molecular movement is greatly restricted. The increase in TSDC intensity after irradiation is relatively small. The inherent polarization potential of silicosis collagen is significantly weaker than that of normal lung collagen, and the polarization activation energy is higher than that of normal lung collagen.
