Thermo-oxidative resistant UHMWPE-based nanocomposites containing hybrid-nanoparticles based on natural anti-oxidants and carbon nanotubes
2015
The use of natural antioxidants is an attractive way to formulate nanocomposites with extended durability and with potential applications in bio-medical field. In this work, Vitamin E (VE) in the form of α-tocopherol and Quercetin (Q) were physically immobilized onto multi-walled carbon nanotubes bearing covalently-linked long-chain alkyl ester groups (CNTs) and the resulting hybrids CNTs-VE and CNTs-Q were used to formulate thermo-oxidation stable ultra high molecular weight polyethylene based nanocomposites. The thermo-oxidation of the nanocomposites was performed at 120°C in air oven. The samples were then subjected to FTIR analyses at different annealing times. The accurate analysis of …
Termo- e foto- degradazione di nano compositi a base di nylon 11
2016
Negli ultimi anni la poliammide 11 (PA11) ha suscitato un notevole interesse in svariati settori industriali industriali.Per ottimizzare la comprensione dei meccanismi che governano la termo e foto ossidazione della PA11, sono stati studiati mediante Matrix-Assisted Laser Desorption Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF-MS) , cromatografia ad esclusione sterica (SEC) e viscosimetria, i processi di degradazione termo e foto-ossidativi che interessano il PA11 ed in particolare i nanocompositi formulati con Cloisite30B

In this work, the thermo- and photo-oxidation stability of functional nitroxide grafted polyethylene (PE) samples was tested.
Degradation of PA 11 nanocomposites: the chemical point of view
2016
We aim to investigate both thermal degradation processes (non oxidative and oxidative) occurring in PA11 nanocomposites and establish the eventual contribution of organo nanoclay modifier on degradation mechanisms.
