“…Refer to our previous work [ 20 ], the simple cubic model was selected as a 3D model. While PPy as a rarely electroconductive polymer, has also been widely applied in biomedical field due to its good biocompatibility and easy polymerization on the surfaces of devices [ 21 , 22 ]. In this study, PPy was coated on the internal and external surfaces of the TPU scaffold through in-situ polymerization, enabling the electrophoretic deposition of electrically charged l -arginine on it [ 23 ].…”

“…This result indicates that the CDC particles are completely wrapped and coated by the PANI. Moreover, the conjugated π-electron system of PANI may cause good interaction through π-π stacking with the sp 2 -hybridized carbons of the CDC in the final composite framework [50]. The detailed discussion of the XPS spectra is given in SI.…”

Polyaniline (PANI)/carbide-derived carbon (CDC) was synthesized by using in-situ chemical oxidative polymerization of PANI in presence of CDC. Conductive electrode ink materials were prepared by using eco-friendly chitosan binder in water media. In the following, symmetrical supercapacitors (SCs) were fabricated by both doctor blade coating and screen printing technique. The electrical conductivity, morphology, specific capacitance, and energy density of these composites were evaluated for their applicability as SC electrodes. Pure PANI with chitosan binder was not printable because of its brittleness, however, the presence of CDC allows the preparation of smooth films which are suitable for electrode preparation. The fabricated composite electrode has a higher specific capacitance (up to 419 F g−1) and higher energy density (up to 6.7 W h kg−1) compared to the pristine CDC electrode. The capacitance of screen-printed SCs was 440–470 mF with an equivalent series resistance of about 27 Ω.

“…However, these PCL scaffolds commonly lack cell recognition sites due to their inherent hydrophobicity . Polypyrrole (PPy), exhibiting good biocompatibility, electrical conductivity, and photoconversion performance, has attracted much attention in biomedical applications . PPy preferentially deposited on the surface of the hydrophobic substrate. , Hopefully, the in situ polymerization of PPy on PCL scaffolds will not only improve the scaffold surface morphology but also introduce electrical conductivity and photothermal conversion to the scaffold, thus achieving many desirable biological effects.…”

Inspired by the negative Poisson’s ratio (NPR) effects of the annulus fibrosus (AF) in intervertebral discs (IVDs), we designed a re-entrant honeycomb model and then 3D printed it into a poly(ε-caprolactone) (PCL) scaffold with NPR effects, which was followed by in situ polymerization of polypyrrole (PPy), thus constructing a PPy-coated NPR-structured PCL scaffold (−vPCL-PPy) to be used as the AF implant for the treatment of lumbar herniated discs. Mechanical testing and finite element (FE) simulation indicated that the NPR composite implant could sustain axial spine loading and resist nucleus pulposus (NP) swelling while displaying uniform stress diffusion under NP swelling and contraction. More interestingly, the NPR-structured composite scaffold could also apply a reacting force to restrain NP herniation owing to the NPR effect. In addition, the in vitro biological assessment and in vivo implantation demonstrated that the NPR composite scaffold exhibited good biocompatibility and exerted the ability to restore the physiological function of the disc segments.
