Mechanical, thermal, and ultraviolet resistance properties of poly(ether–ester)/cerium oxide (CeO₂) composite fibers

Abstract

Poly(ether–ester)/cerium oxide (CeO2) composites with CeO2 nanoparticles of 0, 1, 2, 3, 4, and 5 wt% were prepared from dimethyl terephthalate, 1,4-butanediol, polytetramethylene glycol, and CeO2 nanoparticles by traditional melt polymerization. The Fourier transform infrared, scanning electron microscopy, thermal gravimetric analysis, tensile strength, thermal stability, aging resistance, ultraviolet resistance, and low-temperature elastic recovery of these composites were characterized. The results indicated that introduction of CeO2 nanoparticles into poly(ether–ester) can enhance the mechanical, thermal, low-temperature elastic recovery properties and ultraviolet resistance of traditional poly(ether–ester). In particular, the incorporation of 2 wt% CeO2 nanoparticles endowed poly(ether–ester) with the best performance in mechanical and low-temperature elastic recovery properties.

Polyimide-Based Nanocomposites with Binary CeO2/Nanocarbon Fillers: Conjointly Enhanced Thermal and Mechanical Properties

“…The ability of CeO 2 to release and take up oxygen facilitates its application in the processes where oxygen plays a decisive role, e.g., in vehicle exhaust emission control [ 12 ], in solid-oxide fuel cells [ 13 ] and even in the protection of living cells against the detrimental effects of UV-radiation [ 14 ] and oxidative stress [ 15 ]. Furthermore, nanoceria affects a number of physico-chemical properties of polymers of technical use, viz thermal stability [ 16 ], mechanical strength [ 17 ], optical absorbance [ 18 ], etc.…”

Enhancement of mechanical strength associated with interfacial tension between barium titanate and acrylonitrile–butadiene rubber with different acrylonitrile contents by surface modification

“…Two main methods are usually taken to solve the problem in rubber field. One is adding the traditional reinforcing filler like carbon black or silica, and the other method is grafting coupling agents on the surface of inorganic particles . Carbon black can certainly enhance the mechanical properties and enlarge the dielectric constant of composites, but it will cause huge dielectric loss .…”

Investigations on matrix network characteristics in NBR/silica nanocomposites: Resolving matrix bulk density and network molecular weight and their alterations due to filler‐curing agent interactions

“…Fillers are used in the form of sphere, sheet, rod, etc. with different aspect ratios and in micro and/or nano sizes . Each type of filler has its own specific effect on the rubber properties.…”
