Abstract

Hydrogen is one of the most promising alternatives and clean fuel sources, but it has faced several hurdles due to storage and transportation issues. Several methods have been proposed, developed, and are being improved. Key among these is the use of polymers as safe hydrogen storage media.

This work investigated the polymerization of methyl vinyl ketone using different concentrations 2,2’-Azobis(2-methylpropionitrile) as the initiator in a free radical polymerization mechanism. There was a subsequent analysis of the effect of the initiator concentration on the conversion rate and the molecular weight of the polymers produced with the help of Gel permeation chromatography. FTIR and NMR were used to confirm the formation of the polymer. The thermal properties of the polymers were then determined using thermogravimetric analysis and Differential Scanning Calorimetry. Attempts were also made to create fibers using electrospinning and particles to obtain a higher surface area polymer. Hydrogen storage tests were then subsequently carried out on the products.
