Ultra-high selectivity pulsed plasmachemical deposition reaction pathways

Abstract

Glycidyl methacrylate pulsed plasmas have been investigated using time-resolved in situ mass spectrometry. At low pulsed plasma duty cycles, monomer fragmentation leading to the formation of polymerisation initiator species occurs within each short electrical discharge pulse (ton = microseconds timescale). This is followed by conventional step-wise monomer addition polymerisation occurring during the subsequent extended off-period (toff = milliseconds timescale), culminating in the growth of well-defined poly(glycidyl methacrylate) chains. Key attributes associated with this high selectivity pulsed plasmachemical functional thin film synthesis approach are the absence of the requirement for any additional chemicals (catalyst, solvent, etc.) in combination with very low power consumption (mW) and ambient temperature.
