Antibacterial and antifouling properties of a polyurethane surface modified with perfluoroalkyl and...

Inspired by mussel-adhesion phenomena in nature, a simple, mild surface modification process was elaborated to endow the polyurethane (PU) substrate with antibacterial/antifouling properties. In the present study, polydopamine was coated directly onto polyurethane surfaces. AgNO3 was then added and absorbed onto the surface by the active catechol...

In this paper, the effect of blocked polyurethane prepolymer (BPUP) with four R values (the ratio of -NCO to -OH) and different blending proportions on the characteristics of melamine-urea-formaldehyde (MUF) resin were first investigated. The properties of the modified adhesive systems were examined by dynamic wettability and shear strength. The...

Preparation and assistant-film-forming performance of aqueous polyurethane dispersions

A series of novel trimethylol propane monoesters were synthesized to prepare aqueous polyurethane dispersions (PUD), which were used as a polymer coalescent to assist the film forming of high Tg polyacrylate latexes (PA). The effects of trimethylol propane monoester categories, NCO/OH molar ratios, soft segment contents, dimethylolpropionic acid...

Nanoscale Structure of Urethane/Urea Elastomeric Films

The nanostructure of urethane/urea elastomeric membranes was investigated by small-angle X-ray scattering (SAXS) in order to establish relationships between their structure and mechanical properties. The networks were made up of polypropylene oxide (PPO) and polybutadiene (PB) segments. The structural differences were investigated in two types of...

In this article, we used coal-derived carbon foam (CCF) as a skeleton material to encapsulate the solid-to-solid phase change material polyurethane (PU) to provide PU@CCF composites for functional applications. The obtained PU@CCF composites were characterized by field-emission scanning electron microscopy (SEM), transmission electron microscopy...
