6. Mass Transport through Phase Separated Films - Effects of Ethyl Cellulose Molecular Weight on Cellulose Derivative Blends for Pharmaceutical Coatings
Sammanfattning : Polymer blends are utilized for a variety of applications, not least in pharmaceutical coatings for controlled release of drugs. For instance, blends of ethyl cellulose (EC) and the water-soluble hydroxypropyl cellulose (HPC) can be used to coat drug pellets for oral extendedrelease formulations. LÄS MER
7. Functional Properties and Morphology of Recycled Post-consumer WEEE Thermoplastic Blends
Sammanfattning : This work concerns a waste electrical and electronic equipment blend of recycled plastics (WEEEBR), reprocessed from a low density thermoplastics batch (600 kg) by removal of non-thermoplastic contamination (1.2 weight % (wt%)). LÄS MER
8. Interphases in Polymer Blends
Sammanfattning : The blending of polymers is a useful means of combining and improving the properties of already existing polymers in the development of new materials at reasonable cost. As most polymers are immiscible with each other, heterogeneous blends are often formed. The properties of such blends are strongly determined by the properties of the interphase. LÄS MER
9. Filler Controlled Morphology in Polymer Blends
Sammanfattning : The morphology of a polymer blend can be altered very dramatically when a filler is added. Depending on the mutual interactions of the polymers and their individual interactions with the filler, many different filler distributions are possible. LÄS MER
10. Novel Thermoplastic Material Concepts for High Voltage Cable Insulation - Engineering Immiscible Blends for a Sustainable Future
Sammanfattning : To cope with our growing demand for energy in a sustainable way, efficient long-distance power transmission via high voltage direct current (HVDC) cables is crucial – these cables facilitate the integration of renewable energy into our power networks. For reliable and efficient power transmission, underground and undersea cables require robust insulation materials that possess a high level of mechanical integrity, a low direct-current (DC) electrical conductivity and a high thermal conductivity at the elevated temperatures experienced during cable operation.
