Effect of Immobilization of Phenolic Antioxidant on Thermo-Oxidative Stability and Aging of Poly(1-trimethylsilyl-1-propyne) in View of Membrane Application

Abstract: The effect of phenolic antioxidant Irganox 1076 on the structure and gas permeation behavior of poly(1-trimethylsilyl-1-propyne) (PTMSP) was investigated. Isotropic films as well as thin film composite membranes (TFCM) from pure PTMSP and with added antioxidant (0.02 wt%) were prepared. PTMSP with antioxidant has a significantly higher thermal degradation stability in comparison to pure polymer. The thermal annealing of isotropic films of PTMSP with antioxidant was carried out at 140 °C. It revealed the stabil… Show more

“…The nanocomposite membrane permeability and selectivity were found to rely on the nanofiller contents and dispersion in the polymer matrix. For membrane application, poly(1-trimethylsilyl-1-propyne) matrix material has been found useful [104][105][106]. Albertoa and co-workers [107] formed graphene reinforced poly(1-trimethylsilyl-1-propyne for CO2 separation.…”

“…The prevention of oxidation is the most functional effect that certifies the stabilization activity offered by the involved additive. The large variety of the compounds possessing the inhibition ability upon polymer degradation, namely synthesis antioxidants such as hindered phenols [ 2 , 3 ], natural extracts [ 4 , 5 ], inorganic structures as oxides [ 6 ], polyhedral oligomeric silsesquioxane (POSS) [ 7 , 8 ], complexes [ 9 ] or multicomponent blends [ 10 ] radiation crosslinking [ 11 , 12 ] have been investigated. The problem regarding the improvement of the polymer stability in the presence of antioxidants appears as the background requirement for new applications involving the long-life operation under severe conditions [ 13 , 14 ], the recycling [ 15 ] or food handling [ 16 , 17 ].…”

“…This antioxidant has the bulk structure of a hindered phenolic compound (Figure 2). Irganox 1076 has shown its high efficiency in improving the thermo-oxidative stability of PTMSP [27]. At the same time, when placed in a polymer matrix, bulky Irganox 1076 molecules can restrict macrochain densification caused by relaxation phenomena.…”
