Polyurethane and polystyrene are significant thermoplastic polymers having unique physical properties. This article considers the research trials on the fabrication, remarkable features, and technical applications of the polyurethane/polystyrene nanocomposites. The carbonaceous nano particles and inorganic nanofillers used with the polyurethane/polystyrene blend or copolymer are carbon nanotube, graphene, nanoclay, silica nanoparticles, and others. The considerable improvements in the physical properties of the polyurethane/polystyrene blend may occur through the nanofiller addition. The physical or covalent interactions between the blend or copolymer components and nanofillers may also positively affect the nanocomposite properties. The fabrication strategies used for the polyurethane/polystyrene nanocomposites include solution method, in situ method, melt blending, and several nanocomposite processing approaches. The structure, morphology, electrical conductivity, thermal stability, mechanical strength, and several other physical properties of the high performance polyurethane/polystyrene nanocomposites have been explored. Major application areas identified are shape memory, membrane, and gas transport properties.

Polyurethane (PU), designed with pre-polymer method involving polyol as cross-linker, has been utilized for shape memory applications. Neat PU or PU-PS (polystyrene) interpenetrating network (IPN) samples have been prepared. Functionalized multiwall carbon nanotubes (FMWCNTs) have been utilized as reinforcements. PU composites have been studied for shape recovery time and found better than neat PU. 1wt% incorporation of FMWCNTs in PU has reduced shape recovery time to 22 s for 100% shape recovery, in comparison to neat PU with 62 s of 100% shape recovery. PU-PS IPN has reduced 100% shape recovery time to 17s. Superior hydrogen bonding in neat PU has been suggested as per longer shape recovery time against thermal actuation, in comparison to PU composite and IPNs with FMWCNTs. Decreased thermal stability has been observed with FMWCNTs incorporation, indicating enhanced heat dissipation. Field emission scanning electron microscopy analyses confirmed the difference of morphologies in neat PU, PU composite, and IPNs. A distinctive filler-matrix interaction in IPNs has been observed. XRD confirmed the presence of amorphous component. Rutherford Backscattering Spectrometry and Thermal Gravimetric Analysis have been utilized for analyses. Shape recovery study has been made by a simple experimental set up prepared in lab.

Interpenetrating polymer network are combinations of two or more polymer in network form. The objective of this paper was to evaluate the production and characterization of sequential polyurethane-polystyrene interpenetrating polymer networks from different diisocyanates and varied styrene content using Ximenia americana seed oil as base material. The polymer networks were characterized for their Tensile, Swelling and Thermal properties. The tensile strength and tensile modulus for MDPU-1.50-PS polymer networks, 57.86 ±5.42 - 422.85±15.25 MPa and 2.26±0.91 - 11.08±4.21 MPa respectively are higher than the values represented for HDPU-1.50-PS and TDPU-1.50-PS polymer networks, but the latter polymer networks are higher in values for elongation at break than the former. This is also corroborated by the swelling mass ratio (qm) with values for HDPU-1.50-PS and TDPU-1.50-PS networks higher than those for MDPU-1.50-PS, consistent with lower polystyrene crosslinks in the former polymer networks. Thermal studies present HDPU-1.50-PS-20 as the most stable network at 10% degradation, but at higher degradation temperatures MDPU-1.50-PS-20 polymer network shows stability up to 6000C with 19.40g residual weight of char polymer. This study shows that derivatised Ximenia americana seed oil is suitable as starting material for preparation of an interpenetrating polymer network.
