A novel honeycomb-patterned fluorescent film was fabricated by self-assembly of polystyrene (PS)/poly(ethylene glycol) (PEG)/meso-tetra (N-methy-4-pyridyl) porphinetetratosylate (TMPyP) blend system, at the assistance of diisooctyl sodium sulfosuccinate (AOT). Ordered microporous PS/PEG/TMPyP/AOT blend films were prepared by the breath figure method. The condensed water droplets acted as the sa...

All-Polymer Solar Cells In article number 2103239, Bumjoon J. Kim, Yun-Hi Kim and co-workers develop a series of polymer acceptors with controlled backbone regioregularities side chain structures. All-polymer solar cells based on RRg-C20 acceptor which has regioregular optimal length achieve high power conversion efficiency 15.12%, attributed to electron mobility blend morphology.

Abstracf The successful development of multicomponent polymer systems generally requires careful control of polymer-polymer interactions since this is important for achieving useful mechanical properties, optically clear mixtures (miscibility), coupling of impact modifiers to a bnttle matrix, compatibilization of immiscible polymers, etc. Random copolymers offer a powerful tool for achieving th...

In this paper, research will be carried out to classify the blending behavior of glassy and rubbery polymer in solvent with amines. Commercially preface of a polymer prepared from a new monomer is uncertain and enormously expensive. A strategy to introduce new products into the market without a large investment is to take dissimilar polymers, amines and blend them together to make a new product...

to describe the rheological behavior of polymer blends using emulsionbased (palierne theory) as well as micromechanical models (coranapproach), two immiscible polymeric blend systems of poly(trimethylene terephthalate) (ptt)/polyamide-12 (pa12) and ptt/polyethylene (pe) having different levels of molecular interactions were investigated as model systems. the role of interfacial interactions, vi...

We study the shear-flow effects on phase separation of entangled polymer blends by incorporating into the chemical potential a nonequilibrium contribution due to the flow. The results are compared with those of a previous analysis by other authors which did not modify the chemical potential but used a different assumption for the stress tensor of the blend.

In this report, hierarchical self-organization of poly(tert-butyl acrylate) (PtBA) brushand mixed PtBA/ polystyrene (PS) brush-grafted silica nanoparticles (NPs) in PtBA-b-PS block copolymer and PtBA/PS polymer blend matrices having different molecular weights was investigated using transmission electron microscopy (TEM). Driven by the entropic interactions between the brushes and the polymer m...

Polymer blends of cold water soluble starches (amylose or amylopectin soluble starch) with gelatin were prepared using solvent casting method. The solid state miscibility and polymer-polymer interactions between the constituent polymers were studied by fourier transforms infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorirmetry (DSC), light optical microscopy (OP...

Recently, the single layer polymer solar cell (PSC) based on bulk heterojunction (BHJ) blend of two materials: fullerene derivative [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) and a polymer with alternating units of thieno{3,4–b} thiophene and benzodithiophene (PTB7) has received significant attention [1], since high power conversion efficiency (PCE) of 9.2% has been reported for device...
