摘要：
In this study ultrasonic irradiation has been proposed for organo-modification of SBA-15 with N,N'-(pyromellitoyl)-bis-L-phenylalanine. Chiral poly(amide-imide) (PAI) was synthesized by the direct polymerization of L-chiral diacid and 4,4-diaminodiphenyle sulfone in molten tetrabutylammonium bromide. Different nanocomposites (NCs) of modified SBA-15 and chiral PAI were synthesized by solution intercalation method under ultrasonic irradiation. The structures and morphology of the hybrids were investigated by different techniques. The NCs showed an improvement in the thermal properties in comparison with the neat PAI. Transmission electron microscopy images show well-ordered hexagonal arrays of mesopores SBA and the average distances between neighboring pores is around 3-5 nm.
