Polyurethanes (PUs) thanks to the occurrence of phase separation and biphasic structure prevail over other polymer matrixes for impregnation of conductive fillers and production of conductive composites. A number of carbonous fillers including carbon black, carbon fiber, carbon nanotube, graphite and its derivatives, and fullerene can be loaded into the PU matrixes to impart electrical conductivity. The properties of the carbonous fillers, the filler/PU interactions, and the method of compositing determine the conductive performance of the composite. It is possible to modulate the properties of the conductive PU composites and employ them for a number of electronic applications including but not limited to the strain sensors, electromagnetic interference shielding materials, supercapacitors, and tissue engineering scaffolds. In the present review, first, the distinctive properties of PU as a matrix of conductive composites have been discussed. Then, various carbon fillers loaded into the PU matrixes and their structural and conductive properties have been debated. Thereafter, the fabrication methods of the conductive composites as well as the influential parameters on the electrical properties of the composites have been reviewed to provide an insight into how fulfill a PU composite with the desired electrical performance. And finally, a number of applications of conductive PU composites have been put forward.Highlights Polyurethanes are very capable matrixes for conductive composites. Carbonous fillers can be loaded into the PU matrixes to impart conductivity. Conductive PU composites are employed for a number of electronic applications. Herein, properties, fillers, and applications of PU composites are reviewed.

“…A polyurethane material with good thermodynamic properties and shape memory properties was developed with a compression ratio of 400% and a shape recovery temperature of about 60 °C . A filled polycaprolactone-based shape memory polyurethane foam was developed with better deformation, excellent memory, and filtration performance. , It has the potential to be a sand control screen material, and the processing technology is simpler. However, in general, shape memory polyurethane materials face the problems of a low recovery temperature range and compressive strength, which limit their application range.…”

Open hole combined with a sand filter pipe is the main development mode of an unconsolidated sandstone horizontal well, which causes problems such as shaft wall collapse, sand filter pipe blockage, and even damage. At present, the polyurethane intelligent sand control screen pipe can effectively solve these problems, but its application scope is limited by the downhole temperature and material strength. Therefore, the high-strength shape memory polyphenylene sulfide (SMPPPS) was synthesized by an indoor experiment, then the shape memory performance was analyzed, and the variation law of pore size with composition and processing technology was obtained. Finally, the performance of the SMPPPS intelligent screen was evaluated. It is found that (1) with the increase of the cross-linking agent content, the melt index and melt peak temperature of SMPPPS decrease rapidly at first and then remain unchanged; the cross-linking agent content is set at 4.5 wt %. (2) The shape memory performance of SMPPPS is good, and the recovery ratio can reach 99.8% at 110 °C in 11.8 min. (3) The relationship between the pore size distribution proportion of SMPPPS and the foaming agent content, pore enhancer content, temperature, and pressure is determined through experiments; the main distribution range of pore size increases with the increase of the foaming agent content and temperature and decreases with the increase of the pore enhancer content and pressure. When the foaming agent content is 0.5 wt %, the pore enhancer concentration is 10 wt %, the molding temperature is 320 °C, the molding pressure is 10 MPa, and the main distribution range of pore size is 80–320 μm. (4) The permeability of recovery SMPPPS with a compression ratio of 300% first increases slightly and then decreases slightly with the increase of flow, with a variation range of 420.5–463 mD; the compressive strength range is 9.5–11.4 MPa; the SMPPPS has good adaptability to downhole fluid; the sand retaining accuracy is higher than that of the screen sand filter pipe, but the blockage is more serious.
