Aspects of Polymer Chain Dynamics in Solution Studied by Fluorescence
(University of Waterloo, 2008-04-14)Several pyrene-labeled polymers and polypeptides were synthesized and their chain dynamics were characterized using steady-state and time-resolved fluorescence techniques. Firstly, four series of pyrene-labeled polystyrenes ... -
Drag Reduction with the Aid of Air Bubbles and Additives
(University of Waterloo, 2009-08-21)The effect of additives on friction loss in upward turbulent flow was investigated in this experimental study. Additives such as air bubbles, frother and polymer were added to water flow to study their influence on the ... -
Graphene and Glass Flake Nanocomposites Coatings for Corrosion Mitigation in Chloride Rich Environments
(University of Waterloo, 2018-08-02)Inspired by the needs for the preparation of protective coatings with enhanced protection properties especially corrosion resistance in the oil and gas industry, the research focuses on the synthesis and the evaluation of ... -
Material Modelling for Structural Analysis of Polyethylene
(University of Waterloo, 2007-01-17)The purpose of this work was to develop a practical method for constitutive modelling of polyethylene, based on a phenomenological approach, which can be applied for structural analysis. Polyethylene (PE) is increasingly ... -
Nonlinear Macromechanical Analysis of Polymeric Materials
(University of Waterloo, 2017-05-19)A new methodology for predicting the short term and long term responses of viscoelastic and viscoplastic materials is developed in this research. The methodology aims to predict the behaviour of viscoelastic/viscoplastic ... -
Polymer Based Nanocomposites as Multifunctional Structure for Space Radiation Shielding: A Study of Nanomaterial Fabrications and Evaluations
(University of Waterloo, 2018-06-18)Radiation shielding in space missions is critical in order to protect astronauts and other payloads from radiation damage. Low atomic-number materials such as hydrogen are proved to be efficient in shielding ionizing ... -
Preparation of Functional Polymer Nanoparticles Using Semibatch Microemulsion Polymerization
(University of Waterloo, 2012-05-18)The present project is related to two aspects of research (i) to develop a new technique to synthesize fine nano-size polymer particles with unique and controllable properties; (ii) to synthesize novel functional polymer ... -
Rheological Modification of Polypropylene by Incorporation of Long Chain Branches Using UV Radiation
(University of Waterloo, 2014-11-21)Modification of polypropylene (PP) is important as it aims at changing the molecular structure of PP and synthesizing different grades of PP for different processing applications. These changes include narrowing of the ... -
Starch modification for sustainable and functional material applications
(University of Waterloo, 2019-02-07)Among biodegradable polymers, starch has attracted significant interest and is currently used in numerous industrial applications. This is because of its renewability, biodegradability, abundance, and cohesive film-forming ... -
A Study of Polycarbonate / Poly (butylene terephthalate) Compounding in a Twin Screw Extruder
(University of Waterloo, 2009-03-31)In this work, the compounding of polycarbonate (PC) / poly-butylene terephthalate (PBT) blends was studied for the purpose of improving quality of products with reduced wastage and finally to satisfaction of end users. ... -
Synthesis and Self-Assembly of Metal Carbonyl Building Blocks for Aqueous Colloids with Aggregation-Induced Functions
(University of Waterloo, 2017-04-06)Metal carbonyl complexes (MCCs) are potentially useful for a range of biomedical applications, including cell imaging and bioassay. However, the poor solubility and stability of MCCs in water remain obstacles to their use ... -
Synthesis and Solution Properties of Water-soluble Fullerene Polymeric Systems
(University of Waterloo, 2011-09-20)Water-soluble fullerene containing polymers comprising of poly(2-(dimethylamino) ethyl methacrylate)-fullerene (PDMAEMA-C60) with targeting moieties, poly(oligo(ethylene glycol) methyl ether methacrylate)-C60 (POEGMA-C60), ... -
Versatile Routes for Acrylonitrile Butadiene Rubber Latex Hydrogenation
(University of Waterloo, 2012-06-19)The direct catalytic hydrogenation of acrylonitrile-butadiene-rubber in latex form was studied for the development of a simple process for the modification of unsaturated diene-based polymers. Acrylonitrile-butadiene-rubber, ...
