Preparation and properties of aromatic polyester/TiO2 nanocomposites from polyethylene terephthalate

Unprecedented Influence of Carbon Dot@TiO2 Nanohybrid on Multifaceted Attributes of Waterborne Hyperbranched Polyester Nanocomposite

“…26 The broad band observed at around 681 cm –1 is assigned to the stretching mode of Ti–O bond, whereas the band at 1400 cm –1 arises from TiO 2 lattice vibrations. 9 The stretching and bending −O–H absorption bands of TiO 2 are shifted due to the formation of the nanohybrid. Further, additional absorption bands at 2922 and 2852 cm –1 are assigned to −C–H asymmetric and symmetric stretching vibrations in the nanohybrid, respectively.…”

“…13 Similarly, Santos et al reported only the thermal properties and hardness of the nanocomposites of poly(ethylene terephthalate) (PET) and TiO 2 . 9 Therefore, all of the above-cited reports did not address the above-mentioned unique properties. In addition, they were obtained from petroleum resources and solvent-borne systems were used.…”

“…In this milieu, polymer nanocomposites enjoy synergistic advantages of both polymers and nanomaterials and hence received tremendous interest over the last two decades or so. , Again, polyesters among different polymers deserve special attention due to their inherent advantages like excellent processability and good compatibility with others, low density, good chemical resistance (except alkali), high flexibility, and overall low cost. , However, as they suffer from poor mechanical strength, alkali resistance, and thermal stability, their advanced applications are limited . In this context, to address the above drawbacks and to impart new interesting properties, suitable nanomaterials may be incorporated into them. , Several studies on the incorporation of various inorganic nanomaterials, such as ZnS, graphene, clay, multiwalled carbon nanotubes (MWCNTs), TiO 2 , etc., into the polyester matrices to obtain nanocomposites with desirable properties have been cited in the literature. However, among them, TiO 2 is found to be very interesting as its polymer nanocomposites like epoxy, polyurethane, polyester, , etc.…”

One-Step Deposition of Polyester/TiO2 Coatings by Atmospheric Pressure Plasma Jet on Wood Surfaces for UV and Moisture Protection

“…The peaks found at 1,609 and 1,508 cm −1 are assigned to the C=C stretching vibrations of the aromatic ring. The peak at 1,477 cm −1 is due to the torsional vibrations of CH2 groups, and the strong peaks at 1,241 cm −1 and 1,099 cm −1 are assigned to the asymmetric and symmetric valence vibration of C-O-C bonds, respectively [36,37]. FTIR analysis was performed on polyester/TiO2 powders using the KBr Pellet technique.…”
