Characterization of Electron Beam Irradiated Ethylene Methyl Acrylate Copolymer

Abstract

The effect of electron beam dose on the mechanical, thermal, and electrical properties over ethylene methylacrylate (EMA) copolymer was investigated. The copolymer (Elvaloy 1224) was subjected to electron beam radiation at different doses for cross-linking, with the incorporation of the sensitizer trimethylolpropane trimethacrylate (TMPTMA) at various levels. It was observed that the mechanical properties reached an optimum level around 60 kGy radiation dose and 1 phr sensitizer. Beyond that, an increase in irradiation dose or sensitizer level contributed little to modify the properties further. These observations were supported from spectral studies. Improved thermal behavior was observed from the thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) thermograms. The electrical properties were affected very little by irradiation.

A controllable way to measure the interfacial strength between carbon nanotube and polymer using a nanobridge structure

“…In-situ observation of the embedded CNT before or during the nanopullout process requires a high energy electron beam in a SEM or TEM which could crosslink or damage the polymer and polymer/CNT interface. [27,28] To overcome this challenge and enable a more reliable measurement, we have developed a new nanomechanical method utilizing 3 a novel microstructure where transparency of the embedded part of the CNT within the polymer after the pullout experiment avoids these complications as described below.…”

Electron beam-induced piezoelectric phase in poly(vinylidene fluoride) nanohybrid: effect at the molecular level

“…Electron beam irradiation is frequently used as a tool for soft lithography, fabrication of curled tubular nanostructures created by a rolling up of carbon membranes under in situ transmission electron microscopy electron beam irradiation, manufacturing of heat‐shrinkable polymers, surface modification through control of wetting property (superhydrophobic nature) with active groups and functionalization to get high electrostrictive response for electromechanical transducer, sensor and actuator applications . Electron beam irradiation reduces macroscopic polar ordering due to the disappearance of the remanent polarization in poly[(vinylidene fluoride)‐ co ‐trifluoroethylene] (P(VDF‐TrFE)) at room temperature .…”

Influence of TiO2 in Absorbing Electron Beam Radiation on Silicone Rubber

“…[13]. Besides, other experiments with the impact of electron beam were carried out by several authors [14,15]. Polymers mainly like polypropylene (PP), polyvinyl chloride (PVC), ethylene methyl acrylate (EMA) etc.…”
