“…Another representative conjugated block is poly(phenylenevinylene) (PPV). PPV-b-PMMA (40) has been successfully used to construct BFA films. 248 Zhai et al also synthesized a lightemitting BCP of poly(1,4-distyryl-3,5-dimenylbenzene-co-triethylene glycol) (PDTG, 41) and successfully used it to prepare BFA films.…”

“…477 Our group deposited metal at a title incidence on the BFA film. 40 After removal of the polymer with organic solvent, a metal layer with a honeycomb pattern formed on the substrate, and the pattern could be transferred onto the substrate surface by etching. Using this method, various substrates were patterned, including silicon, glass, and Tedoped silicon.…”

A series of new functional poly(ethylene-co-vinyl alcohol)-g-polystyrene graft copolymers (EVAL-g-PS) with controlled molecular weight (M n 5 38,000-94,000 g mol 21) and molecular weight distribution (M w /M n 5 2.31-3.49) were synthesized via a grafting from methodology. The molecular structure and component of EVAL-g-PS graft copolymers were confirmed by the analysis of their 1 H NMR spectra and GPC curves. The porous films of such copolymers were fabricated via a static breath-figure (BF) process. The influencing factors on the morphology of such porous films, such as solvent, temperature, polymer concentration, and molecular weight of polymer were investigated. Ordered porous film and better regularity was fabricated through a static BF process using EVAL-g-PS solution in CHCl 3 . Scanning electron microscopy observation reveals that the EVAL-g-PS graft copolymer is an efficient compatibilizer for the blend system of low-density polyethylene/polystyrene.

“…The deviation to wCA values closer to PNPMA can be explained in terms of preferential orientation of the amphiphilic polymer to the surface. In addition, the change of configuration to a hc structure plays a relevant role towards a more hydrophobic behaviour 26…”

Polycaprolactone (PCL) scaffolds with a honeycomb (hc) microstructure have been prepared, modified at surface level by plasma processes and evaluated with human mesenchymal stem cells (hMSCs). Thin scaffolds were fabricated by self‐assembly of PCL in the presence of an amphiphilic copolymer under controlled humidity. The surface of the so formed PCLhc scaffolds was modified by Ar and ArO2 plasma discharges and by plasma deposition of allylamine (ALA). Such modification induces composition changes and microstructure modifications as determined by Fourier transformed infrared spectroscopy and scanning electron microscopy. As a consequence of these treatments, the hydrophobic character of PCLhc scaffolds is rectified as derived from water contact angle measurements. The hMSC cytocompatibility of these scaffolds was initially assayed under proliferation conditions evaluating surface–cell interactions by fluorescence and confocal microscopy. Most relevant behaviour was observed for hMSCs cultured onto ALA modified scaffolds in view of the cytoskeleton polarization. These modified surfaces were further explored for differentiation of hMSCs in the presence of vitamin D, giving rise to secreting vesicles and increased extension of the cytoskeleton. These results are promising for the development of cell monolayer tissue regenerating platforms.
