Elasticity and Dynamics of Elastomeric Epoxy Networks: Comparing Simulations and Experiments at High Frequency.

ABSTRACT: This study investigates the elastic and dynamic properties of elastomeric, stoichiometric epoxy networks formed between the telechelic functionalized poly(ethylene glycol) diglycidyl ether (PEGDE) and the linear cross-linker 1,4-diaminobutane across a range of extensional strain rates (10⁷ to 10¹⁰ s^-1), molar masses (n = 3, 5, 8 repeat units), and two reaction extents determining degree of cross-linking through atomistic simulations and compares them with the experimental n = 8 system. Investigated properties are Young's and shear moduli, the C₁₁ elastic constant, the glass transition temperature, and the network's mean-squared-displacement. Results reveal a notable agreement between simulation-obtained and experimental value
