Abstract
- In this work, the thermal degradation of functionalized cage structured polyhedral oligomeric silsesquioxane (POSS) incorporated poly(vinyl alcohol) (PVA) and poly(vinyl alcohol)‐poly (ethylene oxide) (PEO) blend membranes were discussed. PVA‐PEO/POSS and cross‐linked PVA/POSS systems exhibited excellent improvement in thermal stability at lower loading of POSS as compared to pure PVA and uncross‐linked PVA/POSS system. Uncross‐linked PVA and PVA/POSS systems exhibited mainly two degradation steps. However, cross‐linked PVA/POSS systems showed more degradation steps due to the formation of 3‐dimentional network structure in the polymer. The mechanical stability of PVA/POSS and PVA‐PEO/POSS systems at hydrated state were analyzed and observed a remarkable stability even in the wet condition. [ABSTRACT FROM AUTHOR]
