Intervention Introduction

Lindsay Wilson
LIANA: This research expands previous work on Mixed-Matrix Membranes with specific focus on using Zeolite Imidazolate Framework nanocrystals (referred to as ZIFs from here on out) as the main crystal component in the membrane. ZIFs are a prospective component to be used in larger systems because of their demonstrated selectivity of alcohols over water. This is because the inside of the particle is hydrophobic, it repels water. Also the windows of the particle, also called the pores, are large enough to allow alcohol molecules through, including butanol.  
Lindsay Wilson
ALEXA: However, for ZIF-inclusion membranes to filter media efficiently, the ZIF particles need to reach all the way through the base polymer to create an uninterrupted pathway, just like in this example. This means we need to understand how to change the size of the ZIF particles produced to manufacture the membranes. The overall research goal was to create the largest possible ZIFs by adjusting the existing protocol. We manipulated both the ratio of chemicals used and the temperature at which the process is conducted to test their effect on ZIF size.

Materials and Methods

Lindsay Wilson
ALEXA: The original protocol used a 4:1 ratio of two component chemicals, which we used as the controlled element of the experiment for result comparison. We chose to test the ratios 1:1, 2:1, 3, 5, 6, and 7:1. The ratio that resulted in the largest ZIF structure would then be tested under variable temperature.
