WebPolycaprolactone (PCL) is a synthetic, biodegradable polymer. PCL nanofibers can be aligned to mimic an extracellular matrix structure (Manoukian et al., 2024 ). The average diameter of the nanofibers is 500–900 nm ( Engel et al., 2008 ). PCL was first synthesized in the 1930s, but was not commonly used due to its slow degradation rate and ... WebTo break a polyamide, we do the reverse - we add water. Adding water splits the polymer down the middle of the amide group, adding a hydrogen atom to the amine, and a hydroxyl group to the carboxylic acid. This leaves us with our monomers. In this case, we are left with 1,2-diaminoethane and benzene-1,4-dicarboxylic acid.
