A simple approach for morphology tailoring of alginate particles by manipulation ionic nature of polyurethanes

Noteworthy impacts of polyurethane-urea ionomers as the efficient polar coatings on adhesion strength of plasma treated polypropylene

“…Subramani et al reported that chain extenders promote both the molecular weight and the thermal stability of PUDs [33]. We found a well correlation between the related temperature of weight loss at 10% for the synthesized urethane prepolymers extended by PDA and the synthesized polyurethanes in our previous researches [34].…”

Polyurethane cationomers modified by polysiloxane

“…Meanwhile, the KPU 2 film, wherein the mass fraction of PDMS segments is equal to only 3% by weight, is strongly hydrophobic ( γ S < 27 mJ/m 2 ). This hydrophobicity further increases reaching for sample KPU 4 in the presence of 7.18% PDMS value γ S = 18.2 mJ/m 2 , which indicates that the material is practically apolar . The analysis of FSE parameters calculated by the Owens–Wendt method indicates that the decisive share in the value of γ S comes from a component connected with dispersion interactions γ S d dependent on the chemical structures forming chains of synthesized copolymers and is favored by the presence of polysiloxane segments.…”

“…In the case of polyurethane cationomers ‐ as we have shown in our previous works ‐ the important role next to the type of diisocyanate and polyol used to prepare the urethane–isocyanate prepolymer plays an ion segment (created in case of anionomer synthesized from dimethylol propionic or butyric acids and tertiary amine) acting as a counterion . In cationomers, it is an ionic segment, which is formed from N ‐alkyl diethanolamine and counterion prepared from an organic acid; meanwhile, better results are obtained by using bromine alkyls of the appropriate size of the alkyl group as counterion . In polyurethane coatings based on waterborne polyurethanes, reduction in hydrophobicity is achieved by the implementation of fluoride‐containing moieties .…”

Flexible and compatible polymer composite blends based on polyurethane/sodium ionomer/lignin and their properties

“…Polyurethane (PU) has found a broad range of commercial applications because it can be processed by common processing techniques, including cast molding, injection, and extrusion methods . Segmental PUs consisting of hard domains and soft segments have a broad range of applications in various industries .…”
