Sammanfattning : Polymer electrolytes are the most obvious candidates for safe "all-solid" Li-ion batteries and other electrochemical devices. However, they still have relatively poor ionic conductivities, which limits their wider adoption in commercial applications. LÄS MER
Sammanfattning : Nanocomposites (NCs) have been widely studied in the past decades due to the promising properties that nanoparticles (NPs) offer to a polymer matrix, such as increased thermal stability and non-linear electrical resistivity. It has also been shown that the interphase between the two components is the key to achieving the desired improvements. LÄS MER
Sammanfattning : Polymer electrolytes are widely used as ion transport media in vital applications such as energy storage devices and electrochemical displays. To further develop these materials, it is important to understand their ionic conductivity mechanisms. LÄS MER
Sammanfattning : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. LÄS MER
5. Intrinsically Proton-Conducting Benzimidazole Units Tethered to Different Polymer Chain Architectures
Sammanfattning : Proton transport is a fundamental process that can be found in many systems in nature, as well as in technical devices, such as fuel cells, electrochromic devices and various types of sensors. Fuel cell technology is considered as environmentally friendly because fuel cells are not limited by the Carnot cycle, and efficiently converts chemical energy into electrical energy which can be used for powering cars, laptops, buildings etc. LÄS MER
