Influence of component viscoelasticity on the droplet dynamics in immiscible polymer blends Universiteit Antwerpen
Phase behavior of PCBM blends with different conjugated polymers Vrije Universiteit Brussel
In this work the phase behavior of [6,6]-phenyl C61-butyric acid methyl ester (PCBM) blends with different poly(phenylene vinylene) (PPV) samples is investigated by means of standard and modulated temperature differential scanning calorimetry (DSC and MTDSC) and rapid heat-cool calorimetry (RHC). The PPV conjugated polymers include poly(2-methoxy-5-(3?,7?-dimethyloctyloxy)-1,4-phenylene vinylene) (MDMO-PPV), High Tg-PPV which is a copolymer, and ...
Phase behavior of PCBM blends with different conjugated polymers Universiteit Hasselt
In this work the phase behavior of [6,6]-phenyl C(61)-butyric acid methyl ester (PCBM) blends with different poly(phenylene vinylene) (PPV) samples is investigated by means of standard and modulated temperature differential scanning calorimetry (DSC and MTDSC) and rapid heat-cool calorimetry (RHC). The PPV conjugated polymers include poly(2-methoxy-5-(3',7'-dimethyloctyloxy)- 1,4-phenylene vinylene) (MDMO-PPV), High T(g)-PPV which is a ...
Enhanced intrinsic stability of the bulk heterojunction active layer blend of polymer solar cells by varying the polymer side chain pattern Universiteit Hasselt
Organic photovoltaics (OPVs) have acquired huge attention over the past years as potential renewable energy sources, adding attractive features such as aesthetics, semitransparency, flexibility, large area printability, improved low-light performance, and cost-effectiveness to the well-known Si-based photovoltaics. Steady improvements in OPV power conversion efficiencies are continuously reported, notably for bulk heterojunction solar cells ...

On the Processing of Self-healing Polymers, Composites and Blends for (Soft) Robotics KU Leuven
The aim of this thesis is to applicate additive manufacturing techniques to advance in the development of self-healing soft robotics actuators. The research approach taken in this project is founded on these major objectives: - Design, sin thesis and characterization of self-healing materials based on thermoreversible covalent networks for use in additive manufacturing, including the very important design of the rheokinetics of these SH ...
Enhancing the conductivity of carbon nanotube filled blends by tuning their phase separated morphology with a copolymer KU Leuven
We describe an approach to engineer bi-continuous conductive blends of polymers and multiwall carbon nanotubes (MWNTs) by formation of a percolating network of MWNTs in one phase of the blend. Thereto, spinodal decomposition combined with compatibilization by an interfacially segregated random copolymer (rcp) is proposed. A systematic study of the effect of the concentration of the random copolymer poly(styrene-random-methyl methacrylate) ...
Tuning the phase separated morphology and resulting electrical conductivity of carbon nanotube filled PαMSAN/PMMA blends by compatibilization with a random or block copolymer KU Leuven
The mechanism governing the electrical properties for phase separating blends containing multiwall carbon nanotubes (MWNTs) is unravelled by tuning the compatibilization efficiency. Thereto, compatibilization by interfacially segregated block and random copolymers (cp) of poly(styrene-random/block-methyl methacrylate)(PS-r/b-PMMA) was achieved in phase separating blends of poly[(α-methyl styrene)-co-acrylonitrile]/poly(methylmethacrylate) ...
Curing and nanostructure development in epoxy/block copolymer blends KU Leuven
Throughout the last decades, material research has increasingly been exploring the potential of ordered nanostructures to enhance mechanical, electrical, optical or other properties. Nanostructuring most elegantly happens through processes of self-assembly, being the spontaneous association of molecules, through non covalent bonds. When amphiphilic molecules, such as surfactants or block copolymers are introduced in a liquid matrix with which ...
