There is growing interest for new polymer materials and their applications in Micro Electro/Mechanical Systems (MEMS). In this work, we develop recyclable micro-moulds that can be used for microstructuring of new polymer materials, such as precursors and m ...
The combination of reaction calorimetry and supercritical fluids as reactants and/or solvent holds great potential for the optimization of chemical processes using high pressure near-critical and/or supercritical mixtures. The very specific properties of s ...
We report on the first ion-implanted dielectric electroactive polymer actuator that was successfully microfabricated and tested. Ion implantation is used to make the surface of the polymer locally conducting. Implanting the compliant electrodes solves the ...
Several researches have dealt with the thermal initiation of Me methacrylate (MMA) in the past. Some of them already discussed the presence of peroxide contg. species that are formed from dissolved oxygen and the monomer itself as main reason for this init ...
Although biopolymers and synthetic polymers share many common features, each of these two classes of materials is also characterized by a distinct and very specific set of advantages and disadvantages. Combining biopolymer elements with synthetic polymers ...
The different steps associated with the curing of a PVAc/polyester blend are identified and correlated to the mechanism of shrinkage control in the presence of a low-profile additive (LPA). Poly(vinyl acetate) (PVAc) is used as a LPA and is shown to induce ...
As the need for lower mol. wt. acrylates for specialty and molding applications increases, industry is looking for substitute prodn. processes. An alternative to the increasing of initiator and chain transfer agent concn. is working at higher temps. Howeve ...
The kinetic properties of the Me methacrylate (MMA) polymn. at pilot scale for a given temp. range (130-170 Deg) were detd. by differential scanning calorimetry and batch expts. reflecting initiation by MMA peroxides, depropagation of the living chains as ...
Despite progress during the last decade, the behavior of charged macromolecules, polyelectrolytes, including their interactions is not yet completely understood. In particular, interactions with oppositely charged surfaces, which play a significant role in ...
A meso-tetraaryl ruthenium porphyrin complex having four polymerizable vinylbenzoxy groups (2) has been synthesized by reaction of pyrrole with 4-(vinylbenzoxy)benzaldehyde and subsequent metalation with [Ru-3(CO)(12)]. The porphyrin complex was immobilize ...
