In this study, a furan-functionalized urushiol derivative (urushiol-FA) was synthesized using natural urushiol as the starting material. To enhance chain mobility and impart inherent hydrophobicity, flexible poly (dimethylsiloxane) (PDMS) segments were integrated into the bis-maleimide (BMI) framework. Subsequently, a self-healing urushiol-based coating was developed by reversible crosslinking of urushiol-FA with PDMS-BMI via Diels-Alder cycloaddition. To further improve mechanical robustness, multi-walled carbon nanotubes (MWCNTs) were uniformly dispersed within the polymer network as reinforcing components. The surface properties, including surface energy, binding energy, and water contact angle (WCA) were preliminarily evaluated through molecular dynamics (MD) simulation. Subsequent experimental analyses of filler dispersion and WCA demonstrated excellent agreement with computational predictions. Despite a reduction in hydrophobicity resulting from elevated surface energy and non-bonded interactions with water molecules upon MWCNT incorporation, the composite coating containing 2.5 wt% MWCNT still achieved a WCA of 121.6°, attributed to increased surface roughness. Furthermore, MWCNT integration improved the thermal stability, self-healing efficiency, and mechanical properties of the coating. Notably, the composite coatings displayed effective healing performance at both moderate temperature (120 °C) and low temperature (60 °C). After three consecutive damage-healing cycles, the composite coating with 1.5 wt% MWCNT still maintained a healing efficiency of 93.42 % at 60 °C.

Improvement in surface characteristics of graphite nanoplatelets (GNPs) has been achieved through acid functionalization that introduces carboxyl (-COOH) groups to the surface. Polymer nanocomposites are then produced by incorporating varying contents of acid-functionalized GNPs, from 1.5 wt% through 9.0 wt%, into an ethylene propylene diene monomer (EPDM) matrix. This compounding process facilitates efficient dispersion of GNPs inside EPDM and ensures effective bonding between GNPs and the polymer matrix. The inclusion of 6.0 wt% GNPs is found to improve EPDM's storage modulus at high temperatures by more than 210 %, increase its loss modulus by over 156 %, and lower its tan δ by 17.34 %. Relative to EPDM without nano-reinforcement, the nanocomposites produced exhibit superior resistance to deformation via dissipating energy more efficiently, with the loss modulus's contribution to overall deformation resistance lowered. Heat necessary for melting the polymer (EPDM) is also significantly increased after the addition of modified GNPs, with the GNPs concentration 6.0 wt% demonstrating the most favorable result. Additionally, the polymer composite nano-reinforced with 6.0 wt% GNPs shows markedly better thermal stability relative to unreinforced EPDM. The proposed nano-reinforcement strategy can raise the long-term temperature resistance of EPDM by over 50 °C in a steam environment.

In this work, we develop a modified interpenetrated polymer network (IPN) with specifically designed ionic liquid (IL). The acrylic anion of IL ensures its good compatibility with the polyacrylate matrix for achieving both high dielectric constant (11.82@10 Hz) and low stiffness (0.24 MPa); the low ionicity of IL makes it difficult for cations and anions to separate under an external electric field for achieving a desirable breakdown strength (42 V/μm).

By adjusting the alignment of carbon fabric layers during the layup process, SMPCs with various fiber orientations were fabricated. Subsequent experimental characterization of their thermomechanical and shape memory properties revealed several significant orientation-dependent phenomena. To elucidate the underlying mechanisms behind these observations and overcome the limitations of existing formulations, which fail to adequately explain the shape memory mechanisms and the viscoelastic yielding behavior observed experimentally, we developed a novel constitutive model for SMPCs based on the phase transition concept. A dual-phase decomposition strategy is introduced, wherein the rubbery phase is described as a coupling of the SMP's hyperelastic response and the fabric's orthotropic behavior, while the glassy phase combines SMP viscoelasticity with fabric kinematic constraints. To further quantify shape memory effects of SMPCs, the storage strain concept is integrated into the thermodynamic framework. Through energy decomposition, the constitutive equations are rigorously derived based on the Clausius inequality and Helmholtz free energy principles, with phase effectiveness factors incorporated to account for non-ideal behaviors. Good agreement between simulations and experimental results confirms the model's capability to predict anisotropic thermomechanical behavior and shape memory performance.
