“…Although many research papers are written about radiation cross-linking of numerous of polymers [9,10,11], not so many research papers are written about irradiation of polybutylene terephthalate. A small amount of research which is written about radiation cross-linking of polybutylene terephthalate is written [12,13] but it does not examine mechanical properties and thermal resistance.…”

Abstract. The presented article deals with the research of mechanical properties before and after temperature load and temperature stability of modified polybutylene terephthalate by radiation cross-linking. The mechanical properties were measured, at the ambient temperature, by the tensile test on samples which were non-irradiated and irradiated by different doses of the beta radiation and then were temperature loaded. Results demonstrate that PBT has higher values of tensile strength with the increased irradiation dose and it has decreased elongation at break sharply. The purpose of the article is to consider to what extent the irradiation process influences the resulting mechanical properties and temperature stability. The PBT tested showed significant improvement of temperature stability after irradiation. This behaviour leads to the expansion of these materials in the automotive and electrical industry.

“…[12][13][14][15][16] It has been shown that surface roughness, chemical state, optical characteristics, and electrochemical properties can be manipulated by electron beam irradiation. 17,18 In this work, we deposited amorphous ZnSnO (a-ZTO) TFTs under optimum chamber conditions at room temperature by using a direct current (DC) magnetron sputtering system, and report a novel electron beam-irradiated Al 2 O 3 /TiO 2 passivation layer for use as a more reliable active channel layer. The effects of electron-beam treatment on the characteristics of Al 2 O 3 /TiO 2 permeability were then investigated.…”

The effect of an Al 2 O 3 /TiO 2 stacked passivation layer on the performance of amorphous ZnSnO (a-ZTO) thin-film transistors (TFTs) was investigated by comparing field-effect mobility (l FE ) and subthreshold swing after passivation layer deposition. The values observed were 4.7 cm 2 /Vs and 0.64 V/decade, respectively, for uncoated TFTs and 4.6 cm 2 /Vs and 0.62 V/decade for passivated TFTs. In addition, excellent water vapor transmission was observed for electron beam-irradiated Al 2 O 3 /TiO 2 -passivated poly(ether sulfone) substrates in a humidity test, because the Al 2 O 3 /TiO 2 passivation layer can enhance the interface properties between Al 2 O 3 and TiO 2 . To investigate the origin of this enhancement, we performed x-ray photoelectron spectroscopy of both unpassivated and Al 2 O 3 /TiO 2 -passivated TFTs with a-ZTO back-channel layers after Ar annealing.

Makrofol-De polycarbonate is a class of polymeric solid state nuclear track detector which has many applications in various industrial fields. A study of the modification possibility of the dielectric properties of a Makrofol polymer using laser irradiation has been carried out. In the present work, Makrofol samples were irradiated using different fluences between 0.47 and 10.4 J/cm 2 of 5 W infrared laser. The modifications in the laser irradiated Makrofol samples have been studied as a function of fluence using dielectric constant ε , dielectric loss ε , and AC conductivity σ AC measurements. The frequency dependencies (100 Hz-5 MHz) of ε , ε and σ AC at 35 • C were investigated. The dielectric constant ε , dielectric loss ε and AC conductivity σ AC were also found to increase on heating up to 100 • C. The results indicate that ε , ε and σ AC depend not only on the frequency and temperature but also on the laser fluence.
