Abstract:

The work contained in this thesis examines how the properties of polyester film substrates affect the structure and performance of thin coatings vacuum-deposited upon them, particularly with regards to their function as gas barriers for use in packaging. By modifying the surface of a PET film prior to deposition, with either oxygen or argon plasma, an increase in adhesion between the polymer and coating by 50% occurs for both aluminium and SiOₓ layers. A reduction in the density of pinhole defects is also observed after such treatment. A set of silicon oxide (SiOₓ) coatings, deposited using a

Abstract:

Mestrado em Biotecnologia - Biotecnologia Alimentar<br>Over the last years there has been an increasing interest to replace synthetic materials by biodegradable ones, due to the ecological problems. Edible and biodegradable films can be produced using polysaccharides, lipids, proteins and composites, and act as a package without damaging the environment. By choosing a suitable coating composition it is possible to preserve several desired properties of a certain food product. Important properties should be considered, such as mechanical, functional and barrier properties. The main goal of this

The scope of this work is to fathom different possibilities to create functional coatings with polymer brushes. The immobilization of nanoparticles and enzymes is investigated, as well as the affection of their properties by the stimuli-responsiveness of the brushes. Another aspect is the coating of 3D-nanostructures by polymer brushes and the investigation of the resulting functional properties of the hybrid material. The polymer brush coatings are characterized by a variety of microscopic and spectroscopic techniques, with a special emphasis on the establishment of the combinatorial quartz c

This thesis aims to produce functional polymer fibres and films using liquid crystal networks or photoembossing. The work focuses on visual effects in fibres, optical sensing properties and, actuation and morphing properties.

For the former, a micro-structuring technique is combined with a contactless patterning technique: pulsed holography.

Abstract:

Nearly all the deficiencies of conventional vacuum evaporated coatings trace to a single physical property of condensed films: low packing density. One way to increase packing density is to bombard the growing film with ions during deposition, called ion-assisted deposition (IAD). The beginning chapters of this dissertation analyze IAD as a perturbation of the conventional vacuum evaporation process. The experimental chapters begin with an examination of the effect on moisture penetration behavior of oxygen-ion bombarding completed optical filters. Moisture adsorption and desorption is retarde

There are currently no alternatives to body tinting glass to achieve colour, which is a time-consuming and expensive procedure.
