Comparison on photo-initiators for the preparation of methacrylate monolithic columns for capillary electrochromatography

A new strategy for simultaneous synthesis and efficient anchorage of polymer monoliths in native PDMS microchips

“…This morphology difference can be explained by a faster initiation and therefore a faster polymerization rate with IRG, BME and DMPA, leading to the formation of smaller nodules. This is in agreement with the study of Bernab e-Zafon et al [37] who reported that monoliths photoinitiated using DMPA showed smaller globule sizes than those synthesised using AIBN. As such, synthesizing poly (EGMP-co-BAA) MN in PDMS channels without any surface modification remains highly challenging due to oxygen permeability and absorption ability of PDMS [29e32,34].…”

“…To the best of our knowledge, only one work has reported the role of PI on the synthesis of a lauryl-methacrylate MN in silica capillaries [37]. The authors demonstrated that the type and photoinitiator concentration had an effect on the final globule size of the MN.…”

Chromatographic efficiency comparison of polyhedral oligomeric silsesquioxanes-containing hybrid monoliths via photo- and thermally-initiated free-radical polymerization in capillary liquid chromatography for small molecules

“…These excellent features suggest that the photo-polymerization could be adopted as an alternative to thermal polymerization in the synthesis of hybrid monoliths using a variety of monomers and crosslinkers. As a result, similar to common polymeric monoliths, photo-polymerized hybrid monoliths could be synthesized within a specified space and location by the restriction of irradiated areas [18,32,33]. It is expected that more and more hybrid monoliths will be fabricated and applied in the microfluidic chips.…”

Photoinitiated Polymerization of Cationic Acrylamide in Aqueous Solution: Synthesis, Characterization, and Sludge Dewatering Performance

“…It can be carried out at low reaction temperature. Low temperature is beneficial for the production of polymer with high molecular weight by avoiding the side effect of branching and cross-linking, which can be commonly encountered at high temperature [20–22]. Meanwhile, the photopolymerization is easy to operate and control, which requires only simple equipment, economized energy sources, making it an eco-friendly process [21].…”
