Nondestructive analysis of dielectric properties: Application to ion beam irradiated tissue response microfibre

Abstract

The aim of this work was to investigate the effect of 2.4 MeV proton irradiation on the dielectric property of polyethylene terephthalate (PET) microfibre nondestructively. The dielectric constant ε_d of single-microfibre has been measured as-such applying laser diffraction technique. Applying this methodology ε_d is found out to be slightly increases with proton fluence except at the fluence 10¹³ p/cm² where material shows maximum crosslinking. The variations of the biological interaction with ε_d of PET material are correlated. Proton beam modified PET microfibre is therefore accepted to have further potential applications in radiation processing tissue response microfibre, fabrication of medical devices etc.
