Thermosets

Thermosets (epoxy, polyurethane, polyester, ...) are characterized by a macromolecular network architecture of high crosslink density and have a glass transition temperature beyond the application temperature. The network formation might be triggered by heat, light, atmospheric plasma. The following aspects are studied: reaction mechanism, cure kinetics and modelling, reaction-induced structure formation, IPNs, waterborne systems, nanostructured coatings, nanocomposites, pultrusion of composites, reversible vs. irreversible networks. Modulated Temperature DSC is an excellent tool to study this category of polymer materials.

Adhesion and Delamination Mechanisms of Multilayer Organic Field Joint Coatings on Carbon Steel

Adhesion and Delamination Mechanisms of Multilayer Organic Field Joint Coatings on Carbon Steel

Carbon steel pipelines to transport hydrocarbons installed in the sea need to be coated for corrosion protection on the one hand and for insulation to maintain the temperature of the pipe contents on the other hand. At first, this polymer coating is factory applied to the whole length of the pipe, but afterwards cut back (ca. 40 cm) at the ends of each section (12 m) to allow the offshore welding ...

SECEMIN: SElf-healing CEmentitous and MINeral building materials.

SECEMIN: SElf-healing CEmentitous and MINeral building materials.

Aim of the current SBO-project (SIM SHE program on Engineered Self-Healing Materials) is to develop new routes and to further elaborate on concepts for autonomous self-healing of cementitious and mineral building materials. Important objectives are: - regain impermeability of the material and as such safeguard the durability of the structure ("sealing") - restore mechanical properties of the ...

Self-healing polymer networks based on thermoreversible covalent bonding

Self-healing polymer networks based on thermoreversible covalent bonding

A new class of polymeric materials has been developped by introducing reversible covalent bonds into covalently cross-linked polymer network systems, resulting in reversible covalent polymer network systems (RCPNS). In this project the reversible covalent bonds are thermally reversible bonds, e.g. by means of the Diels-Alder reaction between furan and maleimide function groups. Polymer ...

RheoDSC – Development and experimental exploration of a hybrid analytical technique for simultaneous rheological and calorimetric measurements

RheoDSC – Development and experimental exploration of a hybrid analytical technique for simultaneous rheological and calorimetric measurements

To study transformations involving changes in both rheological and thermal properties and to study the influence of flow and flow-induced transitions, a hybrid experimental technique allowing for simultaneous rheometric and calorimetric measurements was developed. The project started from the design and development of a prototype RheoDSC, supported by numerical modelling of the heat transfer and ...

Rheokinetic study of inhibited polyuethanes for resin transfer moulding

In this PhD research first the polyurethane (PUR) and polyisocyanurate (PIR) reaction will be experimentally studied. To do this thermal analysis techniques will be used (DSC, dynamic rheometry and RheoDSC). The next step consists out of modeling the reactions, both PUR and PIR, using a mechanistic model. This is followed by rheokinetic modeling where the link between reaction and viscosity is ...
