“…In Figure 3B, the peak observed at ∼1748 cm −1 (ssp) can be assigned to the CO stretching of the −COCl group. After conversion from COOH-to COCl-terminated silica substrate, the CO peaks were blueshifted by ∼17 cm −1 , showing the changes in the environment of the CO bonds, which was consistent with the observations by Ji et al 95 The ssp polarization combination obtained a peak positioned at ∼1748 cm −1 while two peaks were observed from the ppp polarization combination, as described in the previous section. The extended spectra of −COCl in the region 1400−2000 cm −1 is provided in Figure S7C.…”

Successive surface reactions on hydrophilic silica substrates were designed and performed to immobilize ethanolamine-modified magnetic ferrite-based nanoparticle (NP) for surface characterization. The various surfaces were monitored using sum-frequency generation (SFG) spectroscopy. The surface of the hydrophilic quartz substrate was first converted to a vinyl-terminated surface by utilizing a silanization reaction, and then, the surface functional groups were converted to carboxylic-terminated groups via a thiol–ene reaction. The appearance and disappearance of the vinyl (CH2) peak at ∼2990 cm–1 in the SFG spectra were examined to confirm the success of the silanization and thiol–ene reactions, respectively. Acyl chloride (−COCl) formation from carboxy (−COOH) functional group was then performed for further attachment of magnetic amine-functionalized magnesium ferrite nanoparticles (NPs) via amide bond formation. The scattered NPs attached on the modified silica substrate was then used to study the changes in the spectral profile of the ethanolamine modifier of the NPs for in situ lead(II) (Pb2+) adsorption at the solid–liquid interface using SFG spectroscopy. However, due to the limited number of NPs attached and sensitivity of SFG spectroscopy toward expected change in the modifier spectroscopically, no significant change was observed in the SFG spectrum of the modified silica with magnetic NPs during exposure to Pb2+ solution. Nevertheless, SFG spectroscopy as a surface technique successfully monitored the modifications from a clean fused substrate to −COCl formation that was used to immobilize the decorated magnetic nanoparticles. The method developed in this study can provide a reference for many surface or interfacial studies important for selective attachment of adsorbed organic or inorganic materials or particles.

“…Among them, RGO and GO, with high mechanical properties and good biocompatibility, have potential applications for biomaterials . In particular, GO has different oxygen-rich functional groups, such as carboxyl, hydroxyl, carbonyl, and epoxy groups, which are easily soluble in water and have electronegativity, so GO is easily adsorbed to the positively charged amino group of silk and reduced to RGO in acidic aqueous solution. , As a conductive polymer with good prospects, PANI has advantages of easy synthesis, good conductivity, and stable performance, , but its poor solubility, biodegradability, and processability also limit its use in the biological field. , Because of the good film-forming properties of PANI, in situ polymerization of aniline (ANI) on fabric surfaces is commonly used to prepare PANI conductive textiles. , This method can not only give fabrics good electrical conductivity but also overcome the shortcomings of PANI, such as brittleness, to obtain good mechanical properties . In addition, because ANI is a good electron donor while GO is a good electron acceptor, a weak charge formed by an ANI monomer and GO structure on a surface will result in electrostatic attraction; therefore, GO can be used as a chemical dopant for PANI. , In recent years, electrostatic assembly of GO/PANI on fabrics surface has become a new research topic, mainly for its use as an electrode material for capacitors and smart wearable textiles.…”

Peripheral nerve injury is a common serious disease, and the electrical conductivity of nerve scaffolds is of special significance for nerve regeneration. Here, a highly conductive silk knitted composite scaffold was prepared by utilizing hydrogen bonding and electrostatic adsorption between silk amino, graphene (RGO), and polyaniline (PANI). Compared to traditional in situ polymerization of aniline (ANI), the surface of the RGO/PANI/silk conductive knitted scaffold prepared by two-step electrostatic self-assembly had more uniform PANI particles and lower resistance; when GO was 1 g/L and ANI was 0.4, 0.6, or 0.8 mol/L, the RGO/PANI/silk scaffold had better electrical properties when the conductivity was between 0.62 × 10–3 and 1.72 × 10–3 S/cm. The scaffolds had good conductive stability under different physical stresses and good mechanical properties, wherein ultimately the strength, elongation at break, and Young’s modulus ranges were 28.07–34.97 MPa, 105.91–109.85%, and 10.2–12.48 MPa, respectively, and so they provided good support. Conductive scaffolds had ordered loops, fiber structure, and large pore sizes between 40 and 70 μm. In summary, RGO/PANI/silk scaffold with good conductivity, pore size distribution, mechanical properties, thermal properties had potential applications in the field of peripheral nerve regeneration.
