1. Liquid Crystalline SIloxane Dimers - Advanced Materials with Enhanced Properties
Sammanfattning : The liquid crystal state is a complex state with many kinds of different molecular attractive and repulsive forces that results in various kinds of phases. Since the pioneering works by Vorländer in the early 20th century, liquid crystal research has to a great extent been depending on careful systematic studies of the structure/property relationships in series of similar liquid crystalline materials.

2. Structures and Properties of Ferroelectric Liquid Crystal Displays
Sammanfattning : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. LÄS MER
3. Influence of liquid diffusion on the performance of polymer materials in industrial applications
Sammanfattning : Diffusion of liquids into and through polymers is an important factor that negatively may influence the durability or lifetime of a polymer structure used in industrial applications. In this work two types of polymers, a liquid crystalline polymer (LCP, Vectra A950) and various thermoset resins as used in fibre reinforced plastics (FRP) process equipment were studied with regard to barrier properties, chemical resistance and long-term performance.

4. Mechanical Properties of Liquid Crystal Polymer Fibres
Sammanfattning : Fibres of thermotropic liquid crystalline polymers (LCP) and its blends containing a random coil polymer LCP have been spun at low draw ratio at different temperatures and shear rates. Their mechanical properties have been studied in detail. LÄS MER
5. System-in-a-Package on Low-Cost Liquid Crystal Polymer Substrate
Sammanfattning : System-in-a-Package (SiP) is one of the most advanced approaches to meet the requirements for future high-density electronics packaging. In this thesis, a 3D system-in-a-package concept with embedded active and passive components is proposed, where a liquid crystal polymer (LCP) was used as the base substrate. LÄS MER
