Abstract Difficulties of compounding liquid rubbers are discussed and detailed descriptions are given of mixers for the adequate continuous dispersion of carbon black and of light-weight injection molding machines suitable for the pastes which result; some of the problems of injection molding are outlined and suggested solutions given. The reinforcement of liquid rubbers with textile fibers is discussed and suggestions proposed for the layout of a factory suitable for the processing of liquid rubbers.

In this study, amine functionalized carbon black (ABCB) was synthesized using 4-aminobenzoic acid in a phosphoric acid (PPA)/phosphorus pentoxide (P2O5) medium, and silver-attached carbon black (Ag-ABCB) was prepared by reducing AgNO3 with NaBH4 in the presence of ABCB in ethanol. Elemental, thermogravimetric, and Fourier transform-infrared analyses showed that carbon black (CB) had a well-functionalized 4-aminobenzoic acid. In addition, X-ray photoelectron spectroscopy and X-ray diffraction were used to examine the crystal structure of Ag nanoparticles. Conductive fibers were prepared by melt-spinning using ABCB, Ag-ABCB as a conductive filler, and polyethylene terephthalate (PET) as a polymer matrix. Results confirmed that the fiber that had Ag-ABCB as a conductive filler exhibited the best electrical conductivity. The dispersibility and morphology of the conductive filler in the PET matrix were confirmed through scanning electron microscopy analysis, and Ag-ABCB was the most uniformly dispersed filler in the PET matrix, with good structure.

Conductive Properties

For the development of piezoresistive sensor fibers compounds based on thermoplastic elastomer (TPE) matrix and electrical conductive carbon black powder was used. In this paper the fabrication of piezoresistive fibers by using thermoplastic extrusion method will be demonstrated. With the thermoplastic processing route (e.g. melt spinning process) smart functional senor fibers with a diameter of 300 µm where produced. Their dynamic and static electrical conductive properties where investigated by using a cycling mechanical tensile test in combination with conductive measurement. Compounds of three different SEBS type TPEs and compounds with different content of carbon black were used to investigate the influence on the drift and shift of the electrical signal during dynamic and static strain exposure. By changing the SEBS-Block copolymer matrix and by increasing the carbon black content above 45 wt% stable electrical signal with low relaxation behavior can be achieved.

In this paper conductive yarns were made by coating the yarns with a solution having carbon black nanoparticles (CB) with an average diameter of 18 nm, polyvinyl alcohol (PVA) and water. For a continuous coating deposition it is necessary to obtain a solution of a certain consistency; for this reason, carbon black nanoparticles are mixed with the ingredients so that the resulting film deposited as a thin layer on the yarn to be conductive, and at the same time flexible. The carbon black nanoparticles tend to form aggregates; this is why the solution should be stirred continuously. The yarns used as support are different from the nature, fineness and structure point of view. Several variants of yarns were chosen in order to decide which ones are appropriate for obtaining conductive yarns that keep their specific initial properties. The variants of conductive yarns obtained were tested in terms of physical and mechanical properties (tensile strength, elongation), and from the viewpoint of electrical properties, electrical resistivity was measured. After coating the conductive layer, yarns shows greater rigidity, but can be used to obtain textile materials such as woven fabrics. After performing the measurements, it can be concluded that the yarns coated with a conductive solution based on CB shows electrical conductivity and can be used for obtaining conductive textile fabrics.
