Modified halloysite nanotubes decorated with Ceria for synergistic corrosion inhibition of Polyolefin based smart composite coatings

Construction of core–shell‐structured halloysite nanotubes with TiO2 nanoparticles for ultra‐high‐molecular‐weight polyethylene (UHMWPE) nanocomposites with improved wear resistance

“…The FT‐IR spectra of pristine HNTs and HNTs@TiO 2 are presented in Figure 2G. The characteristic peaks at 3695 and 3620 cm −1 represent the stretching vibrations of inner structural AlOH groups 28 . The characteristics band at 1643 cm −1 reveals the existence of absorbed water.…”

“…The characteristic peaks at 3695 and 3620 cm À1 represent the stretching vibrations of inner structural Al OH groups. 28 The characteristics band at 1643 cm À1 reveals the existence of absorbed water. The peaks at 1101 and 1032 cm À1 belong to the Si O stretching vibration.…”

A new strategy to improve the anticorrosion performance of waterborne polyurethane coating on AA7075

“…53,61,62 The actual content of the encapsulated Ce on HNTs nanocontainers was determined by conducting a TGA measurement in the temperature range of 30-600°C, as illustrated in Figure 4. The raw HNTs exhibited a single decomposition event related to thermal dehydroxylation of the Al-OH group of HNTs at approximately 400°C, 47,63 and almost a total of 14.4 wt-% mass loss of HNTs at 600°C. In the case of mHNTs and Ce@mHNTs, it can be observed that their degradation follows a two-step process.…”

“…Grafting of organo-silanes on the internal surface and edges/defects of HNTs has been commonly employed in various studies. [45][46][47] Although there have been several reports on the corrosion protection of aluminium alloy using inhibitors, 26,[48][49][50] limited attention has been given to the utilization of Ce 3+ -loaded HNTs in a WPU matrix for enhancing the corrosion resistance of AA7075.…”
