Summary: This work presents the fabrication of a hydrophilic, breathable, biocompatible, and washable graphene-decorated electronic textile using silk sericin. The resulting textile exhibits good conductivity, excellent hydrophilicity, biocompatibility, breathability, and flexibility. An integrated multisensing textile is also developed based on this textile, allowing for the collection and analysis of myoelectrical and mechanical signals. This strategy provides a scalable and sustainable way to construct smart wearables.

Summary: MgO has high thermal conductivity and insulation, but readily hydrates with moisture. Coating MgO with graphene oxide (GO) improves its moisture resistance, as the negatively charged GO interacts strongly with the positively charged MgO. Incorporating reduced GO (rGO) further enhances the moisture resistance and thermal conductivity of MgO.

Summary: Smart textiles (ST) are materials capable of detecting and responding to external stimuli, and piezoelectric textiles, which generate electrical energy from mechanical stimulus, are part of this category. This review focuses on the current research and challenges in developing piezoelectric ST. The ability to supply energy to electronic devices and the potential impact on wearable electronic textiles are key considerations in this field.

Summary: Graphene oxide (GO)/hydroxyapatite (HA) composite coatings were successfully prepared on titanium substrates using electrophoretic deposition technology. The coating's microstructure, phase composition, adhesion strength, hydrophilicity, corrosion resistance, bioactivity, antibacterial activity, and biocompatibility were evaluated. The adhesive strength of the coating increased by 76% when the GO content increased from 0 wt% to 12 wt%, and the corrosion rate reached its minimum at (1.493 x 10-3mm/a) with 8 wt% GO. Biomineralization experiments demonstrated the excellent bioactivity of the GO/HA composite coatings. The water contact angle of the composite coatings increased from 20.6 degrees (0 wt% GO) to 38.1 degrees (12 wt% GO). The antibacterial rate of the coating with 5 wt% GO was 96.7%, but decreased to 25% after thermal treatment. In-vitro L929 cell culture experiments confirmed the biocompatibility of the composite coatings with 5 wt% GO.

Summary: Graphene oxide (GO)-coated silk-based electronic textiles (e-textiles) with high electrical conductivity and flexibility are heat-treated at high temperatures (HTTs) for improved flexibility. The resistance change during bending remained low for the heat-treated GO-coated silk (HGS) even after 5000 cycles. The conductive behavior of HGSs can be attributed to structural changes induced by HTTs, as supported by various characterizations.
