Abstract:
Polyurethane/zeolite ۱۳X nanocomposite films were fabricated using solution casting method. The synthesized nanocomposite films were structurally characterized using SEM, TGA and tensile analysis. SEM images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. Better thermal stability of nanocomposite films in comparison to neat polyurethane was shown in TGA analysis. The tensile analyses were carried out for neat polyurethane (PU) and nanocomposite PU/zeolite ۱۳X films. Adding ۵ wt. % of nanozeolite ۱۳X into the polymer matrix caused tensile strength to increase but by increasing zeolite content to ۱۰wt. % and ۲۰wt. % tensile strength decreased. Also, comparison of young’s modulus of samples showed that the young’s modulus and thus stiffness of composites increased with increasing the zeolite content. Strain at breaking point of nanocomposites decreased by increasing the zeolite content, as well.
