چکیده انگلیسی
We have generated porous polybenzoxazine (PBZZ) materials by using a B-a type PBZZ as the matrix and various molecular weights of poly(ε-caprolactone) (pa-PCL) as the labile constituent. The slight degree of hydrogen bonding that exists between the two polymers results in micro-phase separation without an excess degree of aggregation occurring. The porous structures form after hydrolysis of the PCL domains; we characterized them using a variety of techniques, including FT-IR spectroscopy, DSC, TGA, FE-SEM, and DEA. At 298 K and 105 Hz, we obtained a thin, transparent, and nanoporous film that has a very low dielectric constant (1.95).
