“…1c. The 1 H-NMR spectrum of PAI was measured in DMSO-d 6 and was reported in previous work [28]. It seems that designated macromolecule, due to the presence of imide and benzene rings, and existence of amide groups showed good thermal stability and also presence of free hydroxyl groups in the side-chain may create chemical bonds between NPs and organic moieties for better dispersion in BNCs structures.…”

“…The band intensities are assigned as weak (w), medium (m), strong (s) and broad (br). 1 H-NMR spectra were recorded on a Bruker Avance 400 MHz spectrometer operating polymer solution in DMSO-d 6 . The proton resonances were designated as singlet (s), doublet (d) and multiplet (m).…”

“…Two main approaches have been reported for incorporating inorganic nanoparticles (NPs) into polymeric matrices: ex situ methods, i.e., dispersion of the synthesized NPs into polymeric solution, and in situ monomer polymerization methods in the presence of the NPs [4][5][6][7][8]. Different interactions between the polymer matrix and the NPs in the case of ex situ formed composites may happen.…”

“…To avoid the formation of agglomerated NPs in the nanocomposites structure, the combination of inorganic particles with polymers is usually accomplished by surface modification. Several approaches, such as using short-chain polymer structure, coupling agent or a combination of both approaches, were applied to improve the compatibility of nanocomposites by increasing the density of coupling sites [6,8]. Among the different kind of functional polymers PAIs have great interest, due to the favorable balance between processability and performance that being a promising matrix candidate for hybrid materials.…”

Bionanocomposites (BNCs) containing 4, 8 and 12% (w/w) modified ZnO nanoparticles (NPs) were successfully prepared by homogenous dispersion of these NPs in an optically active poly(amide-imide) (PAI) matrix through an ultrasonic process. PAI was synthesized via solution polycondensation of 3,5-diamino-N-(4-hydroxyphenyl) benzamide and N,N -(pyromellitoyl)-bis-L-phenylalanine diacid chloride at low temperature. The ZnO NPs were treated with γ -aminopropyltriethoxysilane (KH550) as a coupling agent to change the surface property of NPs from hydrophilic to hydrophobic nature for better dispersion in PAI matrix. The obtained BNCs were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction, atomic force microscopy (AFM), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM) and thermogravimetry analysis. AFM studies of the BNCs suggest that the ZnO NPs of 20-50 nm in diameter were dispersed in polymer matrices. FE-SEM and TEM results also confirmed the formation of well-dispersed nano ZnO in the PAI matrix.

Zinc oxide (ZnO) nanoparticles have been used as an efficient and recyclable catalyst for one-pot synthesis of 1,8-dioxo-octahydroxanthene derivatives via condensation of aromatic aldehydes and 5,5-dimethyl-1,3-cyclohexanedione under mild reaction conditions in good to excellent yields. ZnO nanoparticles were easily recycled from the reaction mixture and were reused three times without any loss in activity.

The aim of this study was to investigate the crystallization behavior and UV-protection property of polyethylene terephthalate (PET)-ZnO nanocomposits. PET-ZnO nanocomposites containing 0.5-3.0 wt % of ZnO were successfully synthesized by in situ polymerization. The Fourier transformed infrared (FTIR) spectroscopy indicated the silane coupling agent was anchored onto the surface of ZnO. Scanning electron microscope (SEM) images showed ZnO particles were dispersed homogeneously in PET matrix with amount of 0.5-1.0 wt %. Differential scanning calorimetry (DSC) results exhibited that the incorporation of ZnO into PET resulted in increase of the melting transition temperature (T m ) and crystallization temperature (T c ) of PET-ZnO nanocomposites. The crystallization behavior of PET and PET-ZnO nanocomposites was strongly affected by cooling rate. ZnO nanoparticles can act as an efficient nucleating agent to facilitate PET crystallization. UV-vis spectrophotometry showed that UV-ray transmittance of PET-ZnO nanocomposites decreased remarkably and reached the minimum value of 14.3% with 1.5 wt % of ZnO, compared with pure PET whose UV-ray transmittance was 84.5%. PET-ZnO nanocomposites exhibited better UV-protection property than pure PET, especially in the range of UVA.
