“…However, the spectra of PGA-1 before and after thermal treatment are very different from that of PGA-0. The characteristic bands observed at 1412 cm −1 , 1649 cm −1 and 2922 cm −1 are assigned to the stretching vibration of aromatic C=C, amide C=O and aromatic C-H groups, respectively [33,34]. The coupled mode of N-H and C-N stretching in C-N-H groups, also known as amide II band, is obtained at 1536 cm −1 [35,34].…”

To develop graphene-based composite aerogels with improved compressive shape stability that suitable for high temperature applications, poly (m-phenylene isophthalamide, PMIA) with excellent heat resistance and flame retardancy was used as the supporting material. The effects of PMIA content on aerogel morphology, structure, mechanical and thermal properties were discussed. Unlike other polymers, PMIA in the composite aerogels appeared as separate or stacked particles instead of interconnected framework or uniform coatings. Higher PMIA content tended to result in denser aerogels with smaller pores and thinner graphene sheet walls. The densified structure with plenty of PMIA particles incorporated was found to make the aerogel more rigid and less flexible. Their compressive strength therefore was greatly enhanced. Besides, it was also observed that the thermal conductivity of the prepared aerogels increased with the increase of PMIA content. Nevertheless, their thermal conductivity was still less than 0.045 W•m-1•K-1, indicative of considerable thermal insulation ability. Given that, the prepared composite aerogels with enhanced compressive shape stability may have a broad application prospect in thermal insulation.

“…In this work, TiO 2 was introduced into the poly(m-phenylene isophthalamide) (PA) matrix, which is widely used to develop membranes for nanofiltration [ 14 , 15 ], ultrafiltration [ 16 , 17 ], distillation [ 18 ], and reverse osmosis [ 19 , 20 ], as well as for the design of tissue biostructures, batteries, air filters, and in electric elements [ 21 , 22 , 23 , 24 , 25 ]. The active application of PA is associated with its unique properties such as mechanical and chemical resistance, commercial availability and low cost, ease of processing, and the possibility to design highly porous materials [ 26 ].…”

Novel High Flux Poly(m-phenylene isophtalamide)/TiO2 Membranes for Ultrafiltration with Enhanced Antifouling Performance

et al. 2021

Wide application of ultrafiltration in different industrial fields requires the development of new membranes with tailored properties and good antifouling stability. This study is devoted to the improvement of ultrafiltration properties of poly(m-phenylene isophtalamide) (PA) membranes by modification with titanium oxide (TiO2) particles. The introduction of TiO2 particles improved membrane separation performance and increased antifouling stability and cleaning ability under UV irradiation. The developed membranes were characterized by scanning electron and atomic force microscopy methods, the measurements of water contact angle, and total porosimetry. The transport properties of the PA and PA/TiO2 membranes were tested in ultrafiltration of industrially important feeds: coolant lubricant (cutting fluid) emulsion (5 wt.% in water) and bovine serum albumin (BSA) solution (0.5 wt.%). The PA/TiO2 (0.3 wt.%) membrane was found to possess optimal transport characteristics in ultrafiltration of coolant lubricant emulsion due to the highest pure water and coolant lubricant fluxes (1146 and 32 L/(m2 h), respectively), rejection coefficient (100%), and flux recovery ratio (84%). Furthermore, this membrane featured improved ability of surface contamination degradation after UV irradiation in prolonged ultrafiltration of BSA, demonstrating a high flux recovery ratio (89–94%).
