Special Issue Information

Dear Colleagues,

Polyurethanes are versatile polymers for foams, fibers, adhesives, coatings, sealants, and elastomers due to the very broad spectrum of potential properties—the high elasticity of rubber and the good mechanical strength of general plastics—influenced by their chemical composition and the ratio of the two most important components. Polyurethanes are often applied as matrices for polymer composites because they offer possibilities for potential bonding with filler particles. The future success of the polyurethane industry will rely on the development of sustainable polyurethanes and multifunction of polyurethane composites. 

This Special Issue focuses on “Polyurethane Composites for Multifunctional Applications” welcomes contributions in the form of full articles or review articles in topics related to the multifunctional applications of polyurethane composites, such as flame retardancy, electromagnetic shielding, thermoconduction, sound absorption, shape memory property, strengthening and toughening, and biodegradability, including but not limited to additive manufacturing, building, automobile, bedding, and footwear industries. This Special Issue represents a good opportunity for chemists, biochemists, technologists, and engineers to present their research on producing and characterizing polyurethane composites that meet the requirements for sustainability and a circular economy.

High-performance polyether-ether-ketone (PEEK) is highly desirable for a plethora of engineering applications. The incorporation of conductive carbon nanotubes (CNTs) into PEEK can impart electrical conductivity to the otherwise non-conductive matrix, which can further expand the application realm for PEEK composites. However, a number of physical properties, which are central to the functionalities of the composite, are affected by the complex interplay of the crystallinity and presence of the nanofillers, such as CNTs. It is therefore of paramount importance to conduct an in-depth investigation to identify the process that optimizes the mechanical and electrical performance. In this work, PEEK/CNTs composites with different carbon nanotubes (CNTs) content ranging from 0.5 to 10.0 wt% are prepared by a parallel twin-screw extruder. The effects of CNTs content and annealing treatment on the crystallization behavior, mechanical properties and electrical conductivity of the PEEK/CNTs composites are investigated in detail. A non-isothermal crystallization kinetics test reveals a substantial loss in the composites’ crystallinity with the increased CNTs content. On the other hand, mechanical tests show that with 5.0 wt% CNTs content, the tensile strength reaches a maximum at 118.2 MPa, which amounts to a rise of 30.3% compared with the neat PEEK sample after annealing treatment. However, additional annealing treatment decreases the electrical conductivity as well as EMI shielding performance. Such a decrease is mainly attributed to the relatively small crystal size of PEEK, which excludes the conductive fillers to the boundaries and disrupts the otherwise conductive networks. Full article
