This study analyzed the correlation between the degree of conversion (DC) and the plasticization (P) of experimental dimethacrylate-based polymeric matrices. Six polymeric matrices produced with Bis-GMA (G), UDMA (U) and TEGDMA (T) dimethacrylate monomers were studied: G, U, GT55, GT73, GU55, GU73 - (55 = 50/50wt% and 73 = 70/30wt%). Photoactivation was induced by camphoroquinone/ethyl N, N-dim...

The templated self-assembly of block copolymer (BCP) thin films can generate regular arrays of 10-50 nm scale features with good positional and orientational accuracy, but the ordering, registration and pattern transfer of sub-10-nm feature sizes is not well established. Here, we report solvent-annealing and templating methods that enable the formation of highly ordered grating patterns with a ...

Passive samplers for moderately hydrophobic organic compounds (MHOCs) (i.e., log Kow ranging from 2 to 5) are under-developed compared to those that target polar or strongly hydrophobic compounds. The goal of this study was to identify a suitable polymer and develop a robust and sensitive film-based passive sampler for MHOCs in aquatic systems. Poly(methyl methacrylate) (PMMA) exhibited the hig...
