Tuning π-Conjugated Polymers with Heteroatoms: Synthesis of Polytellurophenes and Soluble Polyacetylenes
DownloadFall 2021
This Thesis describes the synthesis and investigation of π-conjugated oligomers and polymers with optoelectronic properties affected by the presence of a heteroatom. Two major classes of polymers are discussed: 1) polytellurophenes, where the backbone is formed by 5-membered heterocycles...

Textile products that repel water and stains while retaining breathability have traditionally been made possible through one widely-used type of chemistry, perfluorinated chemicals or, PFCs. These chemicals have also been used in many fire retardants, as well as—most famously—in the “non-stick”...

Many textile products contain flame retardants to meet flammability or fire safety standards. Flame retardants (FR) inhibit or slow down fire, and thus fulfil a vital role: nobody wants their bed or couch to catch fire and result in flashover. However, research indicates that not all flame...

The textile industry affects the environment in many ways, one of which is through the production of wastewater. In particular, effluent (liquid waste discharged into rivers and seas) from factories contains complex chemicals that pollute the environment, and which could prove to be a serious...
