Electron penetration of polymers
Electron-beam processing or electron irradiation EBI is a process that involves using electrons, usually of high energy, to treat an object for a variety of purposes. This may take place under elevated temperatures and nitrogen atmosphere. Possible uses for electron irradiation include sterilization and cross-linking of polymers. Electron energies typically vary from the keV to MeV range, depending on the depth of penetration required.

The current study demonstrates that methacrylate and acrylate poly ethylene glycol PEG functional oligomers can be effectively impregnated into wood blocks, and cured efficiently to high conversions without catalyst by e-beam radiation, allowing for less susceptibility to leaching, and favorable properties including higher Brinell hardness values.

Electron Beam generators are used to modify surface and bulk properties of polymer films by grafting or crosslinking, but also for initiating polymerisation and curing. Electrons are generated with a wolfram tungsten filament in vacuum. The electrons are accelerated in an electric field towards a window allowing them to escape from the vacuum chamber.
