“…For instance, PI/SiCNW-GS hybrids, where the PI matrix was prepared from PMDA and ODA using DMAc as an organic solvent, exhibited tensile strengths of 79.5–95.5 MPa, tensile moduli of 1608–2233 MPa, and elongations at break of 9.6–23.8% . Meanwhile, the tensile properties of the PI hybrids were much better than those of other polymer-based hybrid materials, such as TiO 2 /PS (tensile strength: 28.5–42 MPa, tensile modulus: 327–520 MPa, and elongation at break: 6.5–11%) and f-MWCNTs-rGO/PMMA (tensile strength: 21.2–28.9 MPa and tensile modulus: 1420–2130 MPa) . The high tensile properties of PI-based hybrids are surely due to the presence of aromatic groups in the main chain and strong intermolecular forces.…”

Therefore, the selection of PI (which has excellent comprehensive performance and is praised as a "problem solver") as the matrix material is very important for stability during further processing and the long-term application of hybrid materials.…”

In this study, a strategy for the fabrication of zirconia-polyimide (ZrO 2 -PI) nanohybrid films with high permittivity (high-k), thermal stability, and excellent mechanical properties has been developed. A colloidal suspension of ZrO 2 nanorods was prepared using the facile microwave-hydrothermal treatment approach. The ZrO 2 -PI nanohybrid film was fabricated by casting an aqueous solution containing water-soluble poly(amic acid) ammonium salt (PAS) and water-dispersible ZrO 2 nanorods followed by thermal imidization. Atomic force microscopy and scanning electron microscopy images indicated that the ZrO 2 nanorods were uniformly dispersed in the PI matrix. Because of the high permittivity of the ZrO 2 nanorods and good compatibility between polyimide and ZrO 2 as well as the nanosize of ZrO 2 , the permittivity increased to 5.1 as the ZrO 2 concentration reached 10% at 10 Hz, while the dielectric loss was as low as 0.05 at 10 Hz. The prepared ZrO 2 -PI nanohybrid films had excellent heat resistance with quite low coefficients of thermal expansion (CTE), as low as 16.3 ppm/K. The ZrO 2 -PI nanohybrid films have excellent thermal stability and good mechanical flexibility. Moreover, no distinct changes were observed for the PAS solution over a storage time of 3 months, after which the nanohybrid film could still be successfully synthesized by thermal imidization. In addition, the water uptake of the ZrO 2 -PI nanohybrid film was approximately 2.5% under 60% relative humidity. The high stability of the PAS precursor, good flexibility, enhanced permittivity, and low CTE behavior of the ZrO 2 -PI nanohybrid films could make this strategy attractive for the ecofriendly design of dielectric polymer nanohybrids as well as for the fabrication of nanohybrid films with potential applications in high charge-storage capacitors and organic field-effect transistors (OFETs) in the flexible electronics industry.

“…Thermal and antibacterial properties of nanocomposites of functionalized‐PMMA were successfully being demonstrated and highlighted the role of AgNPs and Nanoclay with the polymer matrix. [ 23 ] Recently new properties in the area of functionalization had been explored by Sa et al [ 24 ] who examined the effect of functionalized multiwalled carbon nanotubes‐reduced graphene oxide on electrical, mechanical, and thermal properties of PMMA nanocomposites and Hamza et al [ 25 ] who worked for optomechanical properties by investigating the effect of grafting polyamide‐6 fibers with PMMA on its intrinsic optical properties. Therefore by moving through variation literatures, it was found that the scientists were worked for the properties and applications of the functionalized nanocomposites but were inadequate to supply the information at the molecular level.…”

Functional polymers have a wide range of applications, that is, biomedical applications, self‐healing polymers, OLED devices, optical applications, etc. due to improved plasticity, ductility, heat resistance, etc. The present study contributed to reinforcing the concept of functionalization to design facile and cost‐effective material with desired properties or tweak the existing properties of polymers. The advancement of this research study provided insight into the effect of different amino functional groups on the optical properties such as UV shielding, morphology, fluorescence, and crystallinity of PMMA. Results indicated that PHNG3 exhibited very strong UV absorption in comparison with other fun‐PMMAs. The chemical shift (δ) at ~3.5 ppm for β‐NH/NH2 and the existence of aromatic protons at ~7.138 to 9.134 ppm confirmed the functionalization of PMMA.

“…Therefore, the interfacial region between a polymer and a foreign substance has been actively studied. [ 1‐8 ] In evaluating polymeric materials, the glass transition temperature ( T g ) is considered one of the most important factors, particularly for amorphous polymers. In recent years, research on the T g for polymer thin films has attracted considerable attention.…”

The effect of tacticity on the interfacial region between poly(methyl methacrylate) (PMMA) and silica in a PMMA/silica nanocomposite was investigated by differential scanning calorimetry (DSC), Fourier‐transform infrared spectroscopy (FT‐IR), and X‐ray diffraction (XRD). The glass transition temperature (Tg) values of the syndiotactic (st‐) and atactic (at‐) PMMA/silica nanocomposites are higher than those of the neat PMMA. Conversely, the Tg of the isotactic (it‐) PMMA/silica nanocomposite is slightly higher than that of the neat it‐PMMA. DSC and XRD results suggest that the restriction of the PMMA chain mobility in the silica nanoparticle interfacial region heightens as the syndiotactic content increases. FT‐IR results show that this phenomenon is caused by the interaction between the carbonyl group of PMMA and the silanol group on the silicon dioxide surface. Therefore, it can be concluded that the syndiotactic‐rich PMMA has a significantly different molecular mobility from that of the neat PMMA in the interfacial region with silica nanoparticle surface than isotactic‐rich PMMA.
