Development of Hybrid Titania/Polybenzoxazine Composite for Enhance Thermomechanical, Flame Retardancy and Dielectric Properties

Polybenzoxazines (Pbzs) are a recently developed class of thermosetting polymeric materials possessing low surface free energy with nonfluorine or nonsilicon content. In the present study, new type Pbz-BN/TiO2 composite was fabricated using benzoxazine monomer bis(6-phenyl diazenyl-3-phenoxy-3,4-dihydro-2H-1,3-benzoxazinyl) benzonitrile and inorganic TiO2 fillers by simple inexpensive process. The thermal curing method found to be effective for preparing superhydrophobic surfaces combining roughness. presence group in paves way accelerating monomer, as shown DSC analysis. as-prepared Pbz/TiO2 containing 5 wt% generated exhibiting static water contact angle (SWCA) 146°. addition, effect on thermal, mechanical dielectric properties composites investigated detail.
