Dielectric and structural modification of proton beam irradiated polymer composite

Effect of ion beam irradiation on palladium (II) acetyl acetonate dispersed in polymer matrix

“…increasing concentration of dispersed Pd(acac) as well as with fluence. AC electrical properties of pure PMMA were reported in our previous paper (10). The increase in conductivity with concentrations of organometallic compound may be attributed to the conductive phase formed by dispersed organometallic compound in a polymer matrix.…”

“…carriers is almost constant at these frequencies. As the frequency increases, the charge carriers migrate through the dielectric and get trapped against a defect sites and induce an opposite charge in its vicinity, as a result, the motion of charge carriers is slowed down and the value of dielectric constant decreases (10). The decrease in dielectric constant at higher frequency can be explained by Jonscher's power law, i.e.…”

Influence of SHI upon nanohole free volume and micro scale level surface modifications of polyethyleneterephthalate polymer films

“…The gaseous emission affects the A c c e p t e d M a n u s c r i p t 3 | P a g e polymer performance in certain perspectives. The enhancement in the dielectric properties of polymers due to the emission of volatile and low molecular gasses has been reported in the literature [16][17][18][19][20][21].…”

Influence of High‐Energy Ion Irradiation on the Structural, Optical, and Chemical Properties of Polytetrafluoroethylene

“…λ is the wavelength of the X-rays used (1.54Å for Cu K α radiation), θ (in deg) is the angle which is calculated by taking 1/2 of 2θ value as indicated in Fig. 53,54 Since the polymer is highly crystalline in nature and the FWHM value is quite low, hence the values of crystallite size are quite large. K is a constant of proportionality (the Scherrer constant); its value depends on various factors such as the width, the shape of the crystal, and the size distribution.…”
