Phase behavior and physical properties resulted from interactions between blend components was studied, Moreover, potential application in thermal insulation materials and gas separation membranes were also investigated. First of all, a series of PAMAM dendrimers (G0 and G1) products were prepared through repeat the synthesis steps of michael addition and ester amidation. It has different sizes and different number of functional groups terminated. The as-synthesized PAMAM dendrimers were characterized by FTIR, liquid NMR and mass spectrometry (TOF-mass). PMMA with weight molecular weight (Mw) of ~ 18,000 was prepared by emulsion polymerization, then different loading and different generations of PAMAM dendrimers were blending into as-synthesized PMMA to give a series of PMMA composite membranes. Optical properties, phase behavior, thermal stability and mechanical strength of free-standing porous PMMA composite membranes was investigated by UV-visible absorption spectroscopy, SEM, DSC, TGA and DMA. It should be noted that the free-standing PMMA composite membranes exhibited good thermal insulation and gas separation based on the transient plane source (TPS) technique and gas permeability analysis (GPA) measurements, respectively.
