made from the compositions with higher biorenewable content appeared to have more defects and less overall fibers were made in a given electrospinning run the compositions that did not make as many fibers exhibited some fibers were not fully cured when they reached the collector at which point the fluid coalesced this could be easily remedied by implementing a more intense light source a representative sem micrograph of fibers made when dppa is omitted entirely from the composition is shown in fig8 d i e ene component is 100 aeso this composition is described in table 1 and referred to in the text as u201c no dppa u201d and contains about 72 biobased carbon the surface of many of these fibers is not smooth and contains small defects additionally more fused fiber junctions are present these features in fig8 d are phenomenologically consistent with a slower rate of photocuring compared to compositions used to generate the highest quality fibers shown in fig8 a to gain greater insight into the factors influencing photocuring speed and fiber formation real time fourier transform infrared spectroscopy rtir was performed on three different monomer compositions the results showing conversion of chemical groups at short irradiation times lt 5 s are shown in fig9 a this timescale is useful for fiber formation because the fluid jet can break into droplets if it is not photocured extremely quickly additionally rtir data extending to 150.
