A series of styrene/butadiene polymers were combined with up to 90 wt% UiO-66 to form mixed-matrix membranes with varying physical properties. Notably, polystyrene-block-polybutadiene (SBS) membranes retained much of the processability and flexibility of the native polymer component and the porosity, chemical tunability, and adsorption of the native MOF.

in this research, the microstructural of low molecular weight 1,2-polybutadiene (1,2-pbd) was conducted by 1h and 13c nuclear magnetic resonance spectroscopy (nmr) to determine the isomeric contents of 1,4-cis, 1,4-trans and 1,2-vinyl in 1,2-pbd polymer structures. number average molecular weight for low molecular weight 1,2-pbd was measured by nmr techniques and the results were compared with ...

Organic monolayers were formed on mica substrates whose detachment was rate-independent in the absence of thesemonolayers. The pull-off force under dry conditionswasmeasured as a function of contact time (0.01-500 s) and separation rate (0.003-100μm/s; corresponding lateral crack velocity approximately 0.04-1200 μm/s) using a piezoelectric bimorph attachment to a surface forces apparatus.
