Abstract Details

2011, Doctor of Philosophy, Case Western Reserve University, Macromolecular Science and Engineering.
In recent years POSS (polyhedral oligomeric silsesquioxanes) has been incorporated into a number of polymers as a copolymer, graft or as a melt-blend. The advantages gained from using POSS come from its hybrid organic-inorganic nature whose inorganic core provides molecular reinforcement while its variety of functionalization schemes allow for reaction or other interactions with the host polymer. Previous work has shown the ability of POSS to reinforce polymers when incorporated through grafting or copolymerization, but there is a lack of understanding of how to obtain successful reinforcement when using POSS as a melt-blend additive. One hypothesis is that a high degree of POSS-polymer interactions are necessary which promote a pseudo-grafted structure yielding results similar to that of copolymer system. The first part of this thesis (Chapters 2 and 3) will address the role of POSS-polymer interaction in reinforcement. Specifically, Chapter 3 will discuss a new approach to predicting these interactions through the determination of Hansen solubility parameters. This approach however does not take into account the role of processing. Chapter 4 will address this by evaluating the structure-property relationships in melt-spun fiber composites. Finally, Chapter 5 will discuss a different field of polymer composites, polymer clay aerogels. In this work the use of these low-density composites as an oil absorbing media will be discussed.
