Abstract

We have shown new applications and synthetic routes for polymer colloids in the
field of home and personal care products by controlling polymer and/or colloidal
architectures. Our initial aim was to develop functional particles that imparted beneficial
properties to fibrous substrates and as such our first goal was to develop a method for
depositing particles onto such surfaces. Chapter 2 describes the method by which we
achieved this goal, namely adding a small amount of a low glass transition polymer to
an otherwise non-adhesive polymer to enhance colloidal deposition.
Following on from this work we looked into ways in which to impart desirable
characteristics from the particles onto fibres. In Chapter 3 we describe how the use of a
hydrazide functional monomer in polymer gels can provide a continuing slow release of
fragrance molecules that reacts to the environment it is held in such that if the local
fragrance concentration is low then more is released. In Chapter 4 we describe the
synthesis of highly porous particles with controlled pore sizes and the use of such
particles in oil absorption for applications in water-free cleaning systems. The particles
are capable of carrying many times their own weight in oil and are shown to be
reusable.
In Chapter 5 we describe a computational model that predicts the ability of a
particle to stabilize emulsions. The model is highly adaptable and can be used to predict
the surface activity of almost any particle morphology. Chapter 6 builds on this work
and described the synthesis of highly anisotropic polymer particles by templating preexisting
structures and explains their surface activity, or lack thereof.
