A New Benzoxazine Containing Benzoxazole-Functionalized Polyhedral Oligomeric Silsesquioxane and the Corresponding Polybenzoxazine Nanocomposites

Abstract: A new benzoxazole-modified [PhSiO 1.5 ] 8 (OPS) benzoxazine (OPS−Bz) was synthesized and used to prepare polyhedral oligomeric silsesquioxane (POSS)/ polybenzoxazine (PBz) nanocomposites. Fourier transform infrared spectroscopy (FTIR), 1 H NMR, 29 Si NMR, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to characterize the structure of OPS−Bz. The high resolution transmission electron microscopy images of POSS/PBz(30/70) nanocomposites showed a well separated nanostructure… Show more

“…The major advantages of polybenzoxazine include excellent mechanical and thermal properties, low water absorption, high char yield, and low surface free energy (Ishida and Allen, 1996;Ishida and Low, 1997;Kim et al, 1999a,b;Wang et al, 2006;Velez-Herrera and Ishida, 2009;Yagci et al, 2009;Zhang et al, 2012Zhang et al, , 2013. The most interesting and unique characteristics of this class of polymers is their extraordinarily rich molecular design flexibility that allows designing a variety of molecular structures to tailor the desired properties.…”

“…Polybenzobisoxazole (PBO) is a highly conjugated heterocyclic polymer with excellent thermal and electrochemical stability, good mechanical strength, high electron mobility and outstanding oxidative stability [24][25][26][27]. PBO was proved as a good electron transporter that was used to improve the wave absorption of materials [24].…”
