Improving Thermal and Optical Properties of Biodegradable Poly(ethyl vinyl ether-co-maleic anhydride) (PEVE/MA) Copolymer by Encapsulation of TiO₂Nanoparticles Via in situ Radical Polymerization

Novel thermal stable polymeric nanocomposite based on poly(ethyl vinyl ether‐alt‐maleic anhydride) and organo‐modified montmorillonite

“…Figure shows UV‐Vis spectra of OMMT and poly(EVE‐alt‐MA)/OMMT nanocomposites in different ratios. Poly(EVE‐alt‐MA) has a λ max at 290 nm that is attributed to the weak charge transfer between EVE and MA, which EVE acts as electron donor and MA acts as electron acceptor . OMMT has a λ max at 198 nm (Fig.…”

“…Hamadanian et al synthesized poly(EVE‐alt‐MA)/TiO 2 nanocomposite by encapsulation of TiO 2 nanoparticles via in situ radical copolymerization of ethyl vinyl ether and maleic anhydride. Different analytical techniques demonstrated that distribution of TiO 2 nanoparticles into polymer matrix was homogeneous and thermal stability of the poly(EVE‐alt‐MA)/TiO 2 was considerably increased in comparison with pure poly(EVE‐alt‐MA).…”

In,V-codoped TiO2 nanocomposite prepared via a photochemical reduction technique as a novel high efficiency visible-light-driven nanophotocatalyst

“…Further observation indicates that the morphology of samples is very rough, which may be bene-cial to enhance the adsorption of dye due to its great surface roughness and high surface area. 36 Both narrow size distribution of nanoparticles and optimal dispersion are favourable for photoactivity.…”

“…The reason for that might be attributed to the appearance of the new electronic energy state in the middle of the TiO 2 band gap, which results in gap reduction between the conduction band (CB) and valence band (VB) of TiO 2 , allowing TiO 2 to absorb visible light. 36 The band gap values of the pure TiO 2 and In,V-codoped TiO 2 catalysts were calculated 40 using the following equation:…”
