Abstract Domain composition and interfacial structure are critical factors in organic photovoltaic performance. Here, we report neutron reflectivity, grazing-incidence X-ray diffraction atomic force microscopy measurements of polymer/fullerene thin-films to test a hypothesis that these partially miscible blends rapidly develop profiles consisting co-existing phases liquid-liquid equilibrium. We study range polymer molecular weights between 2 300 kg mol −1 , annealing temperatures 120 170 o...
Following annealing at sufficiently high temperatures, well-controlled thin-film bilayers exhibit thermal changes in phase-composition, phase-volume and interfacial roughness that are reversible, irrespective of the starting layer compositions.
The composition profiles of a series model polystyrene/fullerene bilayers are measured, before, during and after thermal annealing, using in situ neutron reflectometry. In combination with grazing-incidence X-ray diffraction measurements, these experiments, which quantify layer compositions as function molecular weight changes both scattering length density thickness, extend corroborate recent measurements on ex annealed samples demonstrate that the rapidly formed systems correspond to two...
Non-equilibrium bilayer mixing on isothermal annealing near T g ; extensive mass-transfer occurs, but the top layer composition, thicknesses &/or interfacial width can become stuck in a local minimum.
Abstract This paper examines beach plastics in a pie chart by proportionality using previous studies that developed characterisation techniques. These techniques include inferring industrial sources of plastic pollution. combines these methods with comparison industry patent statistical proportion for geographical origin inference.
Abstract This paper analyses crystal properties of PCBM when annealed in a bilayer with PS on the top. There are intriguing formations and definite thresholds to varying reproducible morphologies found. suggests that layer greatly influences nucleation rate final morphology.
Abstract This paper outlines experimental results on a model system of PCBM and PS for control parameter exploration crystallisation. layer attributes, annealing temperature amongst others are the variables explored.
