Summary on Grant Application Form |
|
There has been considerable attention focussed on the role of rheology and surface tension in the atomisation of fluids and their deposition onto solid - surfaces. Prior work has considered the role of low molar mass amphiphiles in controlling the deposition of Newtonian fluids. Where the role of polymeric solutes has been considered, only simple linear homopolymers have been employed. Specific studies have also focussed on either atomisation or the impact of droplets on solid surfaces. The proposed study aims to increase the understanding of the mode of action of polymeric additives of more complex architectures, in both the atomisation and deposition of liquid droplets. A range of poly(acrylamide) copolymers containing either anionic or cationic functionality, or a small number of long chain branches will be synthesised. Copolymers will be characterised in terms of their molecular weight distributions and dilute solution properties. A comprehensive study of the influence of polymer architecture on both the droplet size distribution on atomisation and the behaviour of droplets on impact with a solid surface will be conducted, aided by measurements of dynamic surface tension, uniaxial extensional rheology and non-linear viscoelasticity. The results from these experiments will be correlated with empirical measurements of performance carried out by the industrial collaborator. The goal of the proposed study is to establish a meaningful correlation, between molecular architecture and the performance of polymeric additives, through increased knowledge of their mode of action in solution.
