By sequentially performing: a step (I) of dissolving fullerene C.sub.70 in an organic solvent to prepare a fullerene solution; a step (II) of immersing a material carbon fiber in the fullerene solution; and a step (III) of extracting the carbon fiber from the fullerene solution and drying the extracted carbon fiber, a carbon fiber on which fullerene C.sub.70 adsorbs is obtained.

A disclosed vehicle component may include at least one split-ring resonator, which may be embedded within a material. The split ring resonator may be formed from a three-dimensional (3D) monolithic carbonaceous growth and may detect an electromagnetic ping emitted from a user device. The split ring resonator may generate an electromagnetic return signal in response to the electromagnetic ping. The electromagnetic return signal may indicate a state of the material in a position proximate to a respective split ring resonator. In some aspects, the split-ring resonator may resonate at a first frequency in response to the electromagnetic ping when the material is in a first state, and may resonate at a second frequency in response to the electromagnetic ping when the material is in a second state. A resonant frequency of the 3D monolithic carbonaceous growth may be based on physical characteristics of the material.

A composite includes a polymer network including pectin or a pectin derivative; a low-molecular compound having a hydrophilic group in the polymer network; and a polyvalent metal ion coordinated with an anion present in the polymer chain of the polymer network.

A method of manufacturing a functional sheet according to an embodiment of the present invention, comprise powdering a filler with specific functional component and a binder, charging the filler and the binder with second polarity, spraying the binder and the filler onto an upper surface of an electrode plate charged with first polarity opposite to the second polarity, heat-treating the binder and filler, pressing an upper surface of the filler with a rolling roller, and separating the binder and the filler from the electrode plate. Therefore, the method can improve functionality while reducing harmfulness by manufacturing the functional sheet using a powdered filler and binder without using an organic solvent.

Disclosed herein are polysaccharide-elastomer masterbatch compositions and processes for preparing the masterbatch compositions. One method comprises a step of a) mixing i) an aqueous polysaccharide dispersion, or ii) a basic aqueous polysaccharide solution, with a rubber latex solution containing a rubber component to form a mixture. The method further comprises the steps of: b) coagulating the mixture obtained in step a) to produce a coagulated mass; and c) drying the coagulated mass obtained in step b). The masterbatch compositions are useful in preparing rubber-containing articles.

This disclosure provides a tire formed of a body having multiple plies and a tread that surrounds the body. The plies and/or the treads and/or other surfaces of the tire include one or more resonators that respond to being interrogated by an externally generated excitation signal. Multiple resonators formed of electrically-conducting materials are disposed (e.g., printed) on the plies and/or tread and/or other surfaces of the tire. Each of a group of multiple resonators can be individually configured to respond to different frequencies of the excitation signal such that the presence of a response (e.g., a measured attenuation of the excitation signal return) or lack of response (e.g., based on comparison of the excitation signal return to calibration curves) from individual ones of the multiple resonators can be combined to form a serial number that is unique to the tire or other elastomer-containing component (e.g., belts, hoses, etc.) being interrogated.
