Interfacial properties and thermal stability of modified poly(m‐phenylene isophthalamide) thin films

Abstract: Poly(m-phenylene isophthalamide) (PMIA) is a resistant to high temperatures and chemically stable engineering material. The application as coatings and membranes, however, is limited by its poor interaction with other materials. In this report, we describe the molecular modification of PMIA through reaction with dimsyl sodium and 2-iodine-1-ethanol. The substitution of 58% of amide hydrogen by ethanol (etOH) groups produces a material (MPMIA) able to develop regularly structured films on silicon substrate. The… Show more

“…The pure polyamide membrane and M-0.5 hybrid membrane have the N–H stretching vibration at 3320 cm –1 , as shown in Figure . Amide groups I (CO) and amide groups II (C–N–H) are found at 1650 and 1531 cm –1 , respectively . There are two adsorption peaks (989 and 758 cm –1 ) appearing in the hybrid membrane but not in the pure membrane.…”

“…Amide groups I (CO) and amide groups II (C−N−H) are found at 1650 and 1531 cm −1 , respectively. 44 There are two adsorption peaks (989 and 758 cm −1 ) appearing in the hybrid membrane but not in the pure membrane. The different spectra between pure polyamide membrane and hybrid membrane is exactly the MIL-53(Al) characteristic bands, indicating that MIL-53(Al) is present in the surface of the hybrid membrane.…”

“…For instance, poly( m -phenylene isophthalamide) (PMIA) is a highly crystalline fibrous polyaramid that is widely used because of its high thermal resistivity and excellent mechanical properties. 1−3 According to the X-ray analysis of PMIA, the polymer chains are contracted from a fully extended state by the bonds between the phenyl rings and the amide groups and the chains interact via intermolecular hydrogen bonds. 4,5 Furthermore, mutually perpendicular hydrogen bonds are repeated alternately along the chain axis, forming a three-dimensional “jungle-gym”-type network, which contributes to the hydrophobicity, thermal and mechanical stability, and flame resistance of the fibers.…”

“…It is well-known that as protective clothing use, PMIA fibers show poor dyeing properties. Furthermore, the lack of polar functional groups in the polymer chain has limited its role as thermal reinforcement in composites, which poses difficulties in processing PMIA [5,6]. Various routes toward the enhancement the dye ability and the surface adhesion of PMIA are currently being explored.…”
