We report on nanoscale order-disorder transitions of hard segments and their domains composed of 4,4′-methylenebis(phenyl isocyanate) - 1,4-butanediol (MDI-BD), in polycaprolactone-based (Mn = 2000 g/mol) polyurethanes (PCL-PUs), when the free surf

Ionic liquids (ILs) derive their useful properties from molecularly tunable compositions, but methods to diversify anion identities and probe ion speciation remain limited. Here, we demonstrate post-synthetic modification of perhalometallate anions t

The integrated application of green chemistry, life cycle thinking, and systems thinking has the potential to reduce environmental impacts related to the use and production of chemical products or materials. Life cycle and systems thinking are key pe

Segmented polyurethane elastomers for biomedical applications were synthesized and studied at macroscopic (by mechanical testing) and meso/nanoscopic length scales (by atomic force microscopy, AFM). The polyurethanes are composed of 4,4'-methylenebis

This paper considers inkjet printing of optical quality 3D nano-composites from diethylene-glycol diacrylate monomer (DEGDA) containing ZrO2 nanoparticles at varying concentrations. One application for the composites is for gradient refractive index

In order to produce segmented polyurethane polymers (PU) that can be processed readily into elastomeric thin films, a thermally labile blocking agent was used to form an isocyanate prepolymer and prevent reaction with moisture while facilitating the

A series of segmented polycaprolactone polyurethane (PU) polymers is synthesized. One set of polymers ranges in composition from 0 to 100 wt% hard segments (HSs). The syntheses are carried out in solution and the polymers are melt-processed by compre

The UV photopolymerization of diethylene glycol-diacrylate and isobornyl-acrylate based nano-composites was studied with respect to reaction conversion with variations in UV light exposure. The composites contained various amounts of well dispersed Z
