Influence of component viscoelasticity on the droplet dynamics in immiscible polymer blends University of Antwerp
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 ...

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 ...
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 ...
Enhanced intrinsic stability of the bulk heterojunction active layer blend of polymer solar cells by varying the polymer side chain pattern Hasselt University
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 ...

Phase separation as a tool to control dispersion of multiwall carbon nanotubes in polymeric blends KU Leuven
Conducting polymeric materials with stable phase microstructures have a range of potential applications. In this work, it is investigated whether phase separation in polymer blends can be used as a too] to create well dispersed conducting filler rich domains in 3D with controlled morphology, potentially resulting in more effective percolation. The effect of amine functionalized multiwall carbon nanotubes (NH2-MWCNTs) on the thermally induced ...
Construction of the state diagram of polymer blend thin films using differential AC chip calorimetry Vrije Universiteit Brussel
The phase separation behavior of polymer blend thin films of 100 to 150 nm was studied using differential AC Chip calorimetry. By taking advantage of the low sensor and sample mass inherent to chip calorimetry, a new methodology based on temperature jumps was developed. This methodology allowed the construction of the state diagram of polymer blend thin films as evidenced for two model systems (PVME/PS and PVME/Phenoxy) displaying a lower ...
Phase separation in polymer blend thin films studied by differential AC chip calorimetry Vrije Universiteit Brussel
AC chip calorimetry is used to study the phase separation behavior of 100 nm thin poly(vinyl methyl ether)/poly(styrene) (PVME/PS) blend films. Using the on-chip heaters, very short (10 MS-10 S) temperature jumps into the temperature window of phase separation are applied, simulating laser heating induced patterning. These temperature pulses produce a measurable shift in the glass transition temperature, evidencing phase separation. The effect ...
