Abstract The effect of UV light exposure on the properties of hexafluoroisopropylidene-diphthalic anhydride–oxydianiline (6FDA–ODA) polyimide (PI) and polyimide–titanate nanotube (TiNT/PI) composites has been studied using Raman spectroscopy, optical microscopy, nanoidentation and TEM. The degree of polymer photodegradation was estimated by measuring the change in affinity to a positively charged dye (methylene blue, MB). The mechanism of photoassisted transformations in polyimides usually… 
Influence of the chemical functionalization of titanium oxide nanotubes on the non-isothermal crystallization of polypropylene nanocomposites
The surface of titanium oxide nanotubes (TiNTs) was chemically modified after synthesis to determine their influence on the non-isothermal crystallization of polypropylene nanocomposites compared to
Hierarchical mesoscale assembly of PbO2 on 3D titanium felt/TiO2 nanotubular array electrode for anodic decolourisation of RB-5 dye
Hierarchical PbO2 nanoparticles (NPs) were grown by hydrothermal method on TiO2 nanotubes (NTs) at 3D titanium felt, which is simple and scalable method. TiO2 NTs were formed on titanium felt by

New High-Performance Materials: Bio-Based, Eco-Friendly Polyimides
The development of high-performance bio-based polyimides (PIs) seems a difficult task due to the incompatibility between petrochemical-derived, aromatic monomers and renewable, natural resources.
Mechanical properties of carbon nanotubes/epoxy nanocomposites: Pre-curing, curing temperature, and cooling rate
The effects of composite fabrication, such as pre-curing, curing temperature, and cooling rate, were studied. In this work, the pre-curing was defined as heat treatment of Multi-Walled Carbon


The radiation degradation of a nanotube-polyimide nanocomposite
Degradation of polyimide film under vacuum ultraviolet irradiation
The degradation of PI film irradiated with VUV in a wavelength of 5 to 200 nm is investigated. The results show that transparency of PI film decreases obviously after irradiation and more obviously
Effect of simulated low earth orbit radiation on polyimides (UV degradation study)
UV degradation of polyimide films in air and vacuum were studied using UV‐visible, ESR, FTIR, and XPS spectroscopies. The UV‐visible spectra of polyimide films showed a blue shift in the absorption
Growth of carbonyl index in the degradation of polypropylene by UV irradiation
The growth of the carbonyl index in the degradation of polypropylene by UV irradiation, with and without UV stabilizer, has been measured and interpreted. From the kinetics of the degradation process
Probing photodegradation beneath the surface: a depth profiling study of UV-degraded polymeric coatings with microchemical imaging and nanoindentation
Photodegradation of polymer coatings generally involves photooxidation, resulting in the formation of oxidized products, chain scission, and crosslinking. On severe exposure to ultraviolet (UV) light
Titanate nanotubes for reinforcement of a poly(ethylene oxide)/chitosan polymer matrix
The short ultrasound treatment of aqueous solutions containing polymers and a colloidal TiNT mixture prior to drop casting has resulted in some improvements in both hardness and reduced Young's modulus of dry composite films, but further treatment resulted in a deterioration of the mechanical properties of the composite accompanied by a shortening of the nanotubes, as observed by the TEM.
