“…Several typical absorption peaks could be found at about 3400, 1070, 1630 cm –1 or 1530, 1070 820, and 440 cm –1 . Absorptions at ∼3400 cm –1 can be assigned to either C–OH or Si–OH, and absorption at ∼1070 cm –1 can be assigned to either Si–O–Si or C–O Figure b presents the X-ray diffraction (XRD) spectra of Si–O–C and rGO/Si–O–C (with 0.4% rGO).…”

Hydrophilic silicone-modified polyester (Si-PETs) were cured and thermally carbonized to give lithium-ion battery (LIB) anode materials (Si–O–C). Graphene oxides (GOs) were added to Si-PETs, and their effects were analyzed. A preloaded reductant, ascorbic acid, was also added for the purpose of transforming GO to reduced GO (rGO) after Si-PETs were cured. With the cured Si-PET matrix as the barrier, no rGO agglomeration was observed. It is interesting that during carbonization, the insolubility of rGO in Si-PET led to a porous structure, and the well-flexible rGO sheets could be crimped and could encapsulate silicon oxides. Well-dispersed rGO induced a homogeneous porous structure. As LIB anode materials, Si–O–C containing rGO (rGO/Si–O–C) presented higher specific capacities, more stable solid interface films (SEIs), and better cyclabilities. It is suggested that during the charge–discharge process, the porous structure alleviated the volume expansion of Si–O–C, and the encapsulation stabilized the SEI film, thus leading to better performances.

“…One of the strategies commonly used in the preparation of self-healing gels is the formation of interpenetrating polymer networks (IPNs). These are a type of hydrogel that comprise two or more networks that are at least partially interlaced at a polymer scale but are not covalently bound to each other [58,59]. More specifically, semi-IPNs (IPNs in which there is only one component of the assembly crosslinked, leaving the other in a linear form) can improve the self-healing capacity of the hydrogel by chains that flow through the interface at the damaged area [1,60,61].…”

Mimicking nature's self-healing ability has always been desired in science, especially when devices accumulate damage over time with performance, including the loss of function due to deterioration. SHAP (Self-Healing AETA([2-(acryloyloxy)ethyl]trimethylammonium chloride)based Polymer), a hydrogel with autonomous self-healing ability that can be applied for the development of a pneumatic artificial muscle, is presented here. Unlike other self-healing hydrogels, SHAP does not require any external stimulus to self-heal and it presents outstanding anti-drying properties. Few-layer graphene is also incorporated into the polymer network of the hydrogel in order to study the possible influence that the nanomaterial has on the properties of the scaffolds. The mechanical behavior and the self-healing abilities of the resulting hydrogels are analyzed. Moreover, the mechanism of self-healing is discussed in terms of experimental results and theoretical calculations. The data suggest a mechanism based on strong hydrogen-bonding interactions between the water molecules that remain inside SHAP, which keeps the material wet and soft under ambient conditions. Finally, the development of a SHAP-based artificial muscle is presented. The results show good performance of the healed artificial muscles after damage, even with healing periods as short as 10 minutes.

“…The graft or block reaction often occurs between organic functional groups such as −OH, −NH 2 , and alkoxy. − In recent years, the construction of interpenetrating polymer networks and hybrid networks is also an effective way to improve the compatibility. Yang et al introduced a new type of in situ silicone-epoxy IPN system with improved compatibility and mechanical properties. However, its tensile strength was still too low (less than 0.5 MPa) to meet real applications.…”

Flexible thermal protection materials with excellent mechanical and ablative properties were one of the key components in promoting the development of a new generation of aircraft. In the present work, a robust, strongly adhesive, and ablation-resistant PDMS coating was prepared through the covalent connection between PDMS and vinyl-functionalized epoxy resin (EAP) by hydrosilylation. The EAP synthesized by molecular design was uniformly dispersed in the PDMS matrix as an island phase-separation structure. The tensile strength, elongation at break, and shear strength of EAP-modified PDMS (EAP@PDMS) were significantly increased by 575%, 155%, and 183%, respectively, when compared with pure PDMS. Besides, the linear ablation rate (LAR) of EAP@PDMS was greatly declined, which was 80.1% lower than that of pure PDMS, exhibiting excellent ablation resistance. This work opened an avenue toward developing flexible thermal protection coatings with excellent mechanical and ablative properties for aerospace applications.
