## Description

- description: 'Amine-crosslinked epoxy resins represent a large fraction of polymers
    used in structural and coating applications, meaning the characterization and
    modeling of environmental durability and mechanical reliability is of utmost importance.
    In particular, chemical storage tanks, sewage systems, and oil & gas infrastructure
    involve prolonged exposure to organic and inorganic acids. However, the majority
    of meso-scale models for polymer network degradation are more appropriate for
    hydrogels than stiff thermosets; meanwhile, other models developed for acid degradation
    of ester-containing networks are not applicable to amine-cured epoxies due to
    the assumption that crosslink density decreases. In this paper, we report the
    acid uptake and subsequent degradation behavior of bisphenol-F epoxy cured with
    an aliphatic amine, as well as propose a simple but physically meaningful model
    for an ideal 2D network that effectively relates acid uptake and polymer structure
    to the decrease in elastic properties over time. Parameters include crosslink
    density and acid penetration rate, and the only best-fit parameter is the reaction
    rate constant. This analysis can be extended to more complex network structures
    and environmental conditions to model neat resins and composites. '
