While various factors influencing molecular diffusion in epoxies, such as voids and hydrogen bonding, have been widely investigated, the impact of chain mobility remains unclear. The dynamics of internal water molecules in two epoxy compositions with varying ratios were examined by molecular dynamics simulations, along with the relationship to the epoxy polymer chain mobility. The relationship between the characteristic hopping behavior of water molecules and epoxy polymer chain local mobility was explored by evaluating the atomic displacement of chain atoms over a short period, which is a distinctly smaller structural unit compared to segmental chain motion. This analysis showed a trend of high diffusivity of water molecules with high chain local mobility, with stoichiometric epoxy exhibiting higher values compared to epoxide-excess nonstoichiometric epoxy, which agrees with the experimental observations in QENS measurements. Atomic displacement, as the metric of chain local motion, illustrated that the discontinuous hopping behavior of water molecules occurs at locations of high chain local mobility, which leads to the transient interconnection of isolated voids in epoxy. This work suggests that water diffusivity is strongly related to chain local mobility in cross-linked resins because of the restriction of large-scale or segmental chain motion.

The colloidal stability and encapsulation efficiency of these micelles were not dictated by charge density or hydrophilic–hydrophobic balance alone but rather by their synergistic interplay. By fine-tuning both parameters, the micelles achieved optimal stability and drug release properties. The customized synthesis process-RAFT polymerization of 4-vinylpyridine (4VP) with a (PEG)-based macro-RAFT agent, followed by quaternization with chloride-functionalized PCL (Cl-PCL_n), allowed precise modulation of these factors, demonstrating that the balance between electrostatic and hydrophobic interactions is critical for achieving robust micellar structures with high drug-loading capacity and controlled release behavior. The (PEG)₁₃-(P4VP⁺₁₄₀-PCL₃)_75% micelles with higher charge density and minimal chain length of PCL exhibited high encapsulation efficiency (88%) and sustained QR release, with over 94% antioxidant activity retention. The results confirmed the formation of stable micelles with a critical aggregation concentration (C.A.C.) of 0.34 mg/L, making them ideal for physiological applications. In vitro genotoxicity assays demonstrated an inverse relationship between charge density and DNA interaction, with (PEG) shielding mitigating genotoxic effects. Acute toxicity studies showed that the treatments were well-tolerated, and in vitro degradation studies indicated effective polymer breakdown in acidic conditions at 37 °C, with a 60% reduction in molecular weight after 6 days. Overall, these findings highlight the critical role of optimizing charge density and hydrophilic–hydrophobic balance in the design of nanocarriers for hydrophobic drugs.
