Highly Soluble Carbon Nanotubes With Enhanced Conductivity

View page
US Patent:
20120326093, Dec 27, 2012
Filed:
Jun 22, 2012
Appl. No.:
13/530471
Inventors:
Christopher Landorf - Springfield MO, US
Assignee:
BREWER SCIENCE INC. - Rolla MO
International Classification:
H01B 1/12
B82Y 40/00
B82Y 30/00
US Classification:
252500, 977742, 977750, 977752, 977734, 977847
Abstract:
New methods for preparing carbon nanotube films having enhanced properties are provided. The method broadly provides reacting carbon nanotubes (CNTs) and compounds comprising a polyaromatic moieties in the presence a strong acid. During the reaction process, the polyaromatic moieties noncovalently bond with the carbon nanotubes. Additionally, the functionalizing moieties are further functionalized by the strong acid. This dual functionalization allows the CNTs to be dispersed at concentrations greater than 0.5 g/L in solution without damaging their desirable electronic and physical properties. The resulting solutions are stable on the shelf for months without observable bundling, and can be incorporated into solutions for printing conductive traces by a variety of means, including inkjet, screen, flexographic, gravure printing, or spin and spray coating.

Printable Carbon Nanotube-Based Carbon Dioxide Sensor

View page
US Patent:
20230065235, Mar 2, 2023
Filed:
May 16, 2022
Appl. No.:
17/745375
Inventors:
- Rolla MO, US
Christopher Landorf - Springfield MO, US
Vijaya Kayastha - Springfield MO, US
International Classification:
G01N 33/00
G01N 27/414
Abstract:
A carbon nanotube sensor device for detecting COand methods of its production and use. A printable polyethylenimine (PEI)-functionalized carbon nanomaterial paste may be used to form the active sensing layer of the device, which is particularly sensitive to CO. A separate printed heating layer may be used to maintain the working temperature of the sensor, as well as to remove and/or clear volatile gases from the sensor.

Is-Fet Nitrate Sensor And Method Of Use

View page
US Patent:
20230003684, Jan 5, 2023
Filed:
Jul 1, 2022
Appl. No.:
17/856932
Inventors:
- Rolla MO, US
Xi Cao - Tracy CA, US
Christopher Landorf - Springfield MO, US
Zun Chen - Springfield MO, US
Alec Neeson - Springfield MO, US
Weston Bowen - Springfield MO, US
Austin Peters - Springfield MO, US
International Classification:
G01N 27/414
G01N 33/18
G01N 27/02
Abstract:
A carbon nanotube (CNT) ion-selective field effect transistor (IS-FET) integrated device is used to detect nitrate ion in water. The device is operated as an IS-FET sensor, holding the measured potential between the drain electrode and an external reference electrode constant with a potentiometric circuit. Transduction occurs by changes in the effective CNT film gate potential with changes in the phase boundary potential of an ion-selective membrane (ISM) film. Moreover, the nitrate ISM film makes the device highly selective towards nitrate sensing. This printable IS-FET nitrate sensor enables real-time and high-resolution measurements and recording of nitrate ion in water at low cost.

Energetic Pulse Clearing Of Environmentally Sensitive Thin-Film Devices

View page
US Patent:
20180067066, Mar 8, 2018
Filed:
Sep 5, 2017
Appl. No.:
15/695557
Inventors:
- Rolla MO, US
Jonathan J. Fury - Springfield MO, US
Erik Harker - Springfield MO, US
Christopher Landorf - Springfield MO, US
International Classification:
G01N 27/14
G01N 33/00
Abstract:
A process and electronic hardware and software system for rapidly heating and cooling an active sensing layer of a gas sensor is provided. A series of high-energy pulses is run through a CNT electrically-active layer, heating the layer to varying temperatures. The influence by various gases on the electrical conductivity of the layer can be used to identify gases (e.g., water vapor, alcohol, methane, O, CO, and CO). Advantageously, the same structure can also be used as a nanoheater, either within or outside the context of the gas sensor. The device can acquire a unique gas spectra in seconds, and thus accurately determine gas type and mixtures of gases based on a library of known spectra.

All-Organic Inductor-Capacitor Tank Circuit For Radio Frequency Sensor Applications

View page
US Patent:
20160050757, Feb 18, 2016
Filed:
Apr 18, 2013
Appl. No.:
13/865841
Inventors:
- Rolla MO, US
Wu-Sheng Shih - Ozark MO, US
James E. Lamb III - Rolla MO, US
Christopher Landorf - Springfield MO, US
International Classification:
H05K 1/16
H01F 27/28
H05K 1/03
H01G 4/008
H01G 4/14
Abstract:
The present invention provides novel tank circuits that are totally passive, and they are made of conductive-grade carbon nanotubes (CNTs) on substrates, and preferably flexible substrates. These components and structures contain no traditional electronic materials such as silicon, metal oxides, or ceramics, and they are totally organic. They may be used in applications where the resonant frequency and amplitude of the sensor can be modulated by a thermal, mechanical, or chemical signal, such as temperature, strain, pressure, vibration, or humidity. All-organic, and consequently combustible, passive RF sensors have unique applications for defense and consumer industries.
