In this study the morphology of spin-casted films polymers blended with [6,6]-phenyl C61-butyric acid methyl ester (PCBM) has been studied. It was found that lateral structure formation in is favored by rapid solvent evaporation and strong polymer−PCBM repulsion. The homogeneous slow weak effect rate opposite what for spin-casting polymer−polymer blends. results can be explained kinetics phase separation behavior involving limited solubility crystallization PCBM.
Novel brush coatings were fabricated with glass surface-grafted chains copolymerized using surface-initiated atom transfer radical polymerization (SI-ATRP) from 2-(2-methoxyethoxy)ethyl methacrylate (OEGMA188) and acrylamide (AAm), taken in different proportions. P(OEGMA188-co-AAm) brushes AAm mole fraction >44% (determined XPS TOF-SIMS spectroscopy) nearly constant the depth copolymer composition (TOF-SIMS profiling) exhibit unusual temperature-induced transformations: The contact angle of...
Poly(methacrylic acid) (PMAA) is a well-known pH-responsive polymer with underexplored temperature-responsive properties. This study investigated the properties of PMAA grafted brush coatings, synthesized via SI-ATRP polymerization sodium...
Coexisting polymer phases are characterized by very small interfacial energies, even well below their critical solution temperature. This situation should readily lead to the exclusion of one from any interface that favors other. Such complete wetting behavior a binary mixture statistical olefinic copolymers is reported. By means self-regulating geometry, it found thickness layer at polymer-air interface, growing other coexisting phase, attains macroscopic dimensions, increasing...
The fabrication of multifunctional, thermoresponsive platforms for regenerative medicine based on polymers that can be easily functionalized is one the most important challenges in modern biomaterials science. In this study, we utilized atom transfer radical polymerization (ATRP) to produce two series novel smart copolymer brush coatings. These coatings were copolymerizing 2-hydroxyethyl methacrylate (HEMA) with either oligo(ethylene glycol) methyl ether (OEGMA) or N-isopropylacrylamide...
Blends of the low-bandgap polymer poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-5,5- (4',7'-di-2-thienyl-2',1',3'-benzothiadiazole] (APFO-3) and fullerene derivative [6,6]-phenyl–C61–butyric acid methyl ester (PCBM) were spin-coated from chloroform solution into thin films, which examined with dynamic secondary ion mass spectrometry. For blends high PCBM content, depth profiles show composition waves that caused by surface-directed phase separation during spin-coating. The formation such...
Poly( n-butyl methacrylate) (PBMA) or poly( acrylate) (PBA)-grafted brush coatings attached to glass were successfully prepared using atom-transfer radical polymerization "from the surface". The thicknesses and composition of PBMA PBA examined ellipsometry time-of-flight secondary ion mass spectrometry (ToF-SIMS), respectively. For PBMA, glass-transition temperature constitutes a range close physiological limit, which is in contrast PBA, where around -55 °C. Atomic force microscopy studies...
Antibodies are commonly used as detection elements in biosensors. Antibody orientation on transducer surface determines immunological recognition and biosensor performance. Although a relation between antibody adsorbed amount Γ was predicted, assuming close packing of proteins, even applied to infer the preferred from indirect analysis, issue has not been so far examined experimentally with techniques probing directly for wide range covering all possible orientations. In this work,...
Non-cytotoxic, temperature-responsive and antibacterial poly(di(ethylene glycol)methyl ether methacrylate) - POEGMA188 based nanocomposite coatings attached to a glass surface were successfully prepared using ATRP polymerization. The thickness, morphology wettability of the resulting analyzed ellipsometry, AFM contact angle measurements, respectively. strong impact thicknesses grafted brush content AgNPs on temperature-induced changes was demonstrated. In addition temperature-dependent...
We investigate effects of two spin-coating parameters, relative humidity (5% < or = RH 80%) in ambient atmosphere and water content (3 wt % f(H2O) 20 %) solution (rich tetrahydrofuran), on the structure breath figures (BF) formed spin-cast films polar poly(methyl methacrylate) (PMMA) PMMA mixed with nonpolar polystyrene (PS). Film morphologies, examined atomic lateral force microscopy, are analyzed integral geometry analysis to yield morphological BF measures. In PMMA, added has much...
Polymer/fullerene solar cells with three different device structures: A) diffuse bilayer, B) spontaneously formed multilayer, and C) vertically homogenous thin films, are fabricated. The photocurrent/voltage performance is compared it found that the self-stratified structure (B) yields highest energy conversion efficiency.
Poly(4-vinylpyridine)-grafted brushes demonstrate a thermal response of their wettability (stronger than that for spin-coated films), surface morphology, and protein adsorption.
