Designing Acrylic Block Copolymers with Multiple Hydrogen Bonding or Multiple Ionic Bonding
The dynamic characteristics of hydrogen and ionic bonding contributes to the reversible properties of acrylic polymers, opening new avenues for designing materials with mechanical strength and processability. These non-covalent interactions function as physical crosslinks, which provide enhanced …

Exploring Multiple Hydrogen Bonding and Ionic Bonding in the Design of Supramolecular Polymers
… processability and recyclability. Dynamic bonding with multiple binding sites, such as multiple hydrogen bonding or multiple ionic bonding, exhibits much stronger binding strength compared to the counterparts containing only a single binding site, thereby allowing for enhanced mechanical …

Living Polymerization for the Introduction of Tailored Hydrogen Bonding
… comprising both covalent and non-covalent bonding to tune ultimate physical properties, a variety of methodologies and functionalization strategies were employed. First, protected functional initiation, namely 3-[(N-benzyl-N-methyl)amino]-1-propyllithium and …

The Influence of Branching and Intermolecular Interactions on the Formation of Electrospun Fibers
… the 2.7 power. Polymers modified with quadruple hydrogen bonding groups were investigated to determine the role of intermolecular interactions on the solution rheological behavior and the electrospinning process. In nonpolar solvents, the hydrogen bonding functionalized polymers displayed …

Synthesis and Characterization of Novel Polymers for Functional and Stimuli Responsive Silicon Surfaces
… changes in surface hydrophobicity. In spite of multiple solvent exposures, the copolymer films remained stable on the surface indicating that the observed changes in surface properties were due to selective solvent induced reversible rearrangement of the copolymer blocks. The chemical …

Non-Covalent Interactions in Block Copolymers Synthesized via Living Polymerization Techniques
Non-covalent interactions including nucleobase hydrogen bonding and ionic aggregation were studied in block and end-functional polymers synthesized via living polymerization techniques such as nitroxide mediated polymerization and anionic polymerization. The influence of non-covalent association on …

Synthesis and Characterization of Functional Biodegradable Polyesters
… thymine terminal units were also prepared. The hydrogen bonding associations between complementary PDLLA macromolecules depended strongly on molar mass and hence, the concentration of multiple hydrogen bonding units. 1H NMR spectroscopy confirmed the formation of hydrogen-bonded complexes with a …
