Appl. No.:

17/680195

Inventors:

- Malibu CA, US
John VAJO - West Hills CA, US
Jason GRAETZ - Calabasas CA, US

International Classification:

G01N 27/04

Abstract:

Some variations provide a system for sensing a chemical active in a coating, the system comprising: a coating disposed on a substrate; a chemical active contained within the coating, wherein the chemical active is mobile within the coating, and wherein the chemical active is ionically and/or electrically conductive; a first electrode and a second electrode configured to measure AC impedance within the coating; and an electrical meter configured in electrical communication with the first and second electrodes to read a signal corresponding to the AC impedance. Some methods comprise: pressing electrodes against the coating; reading out an impedance value; and converting the impedance value to a concentration of the chemical active in the coating. Other methods comprise: adding a solvent to a coating surface; pressing electrodes against a surface region; reading out an impedance value; and converting the impedance value to a concentration of the chemical active in the coating.

A01N 33/12

Abstract:

Antimicrobial coatings that are transparent and not easily stained are disclosed. Some variations provide a transparent antimicrobial structure comprising: a discrete solid structural phase comprising a solid structural polymer with a glass-transition temperature from 25 C. to 300 C.; a continuous transport phase interspersed within the discrete solid structural phase, wherein the continuous transport phase comprises a solid transport material; and an antimicrobial agent contained within the continuous transport phase, wherein the antimicrobial agent is dissolved in a fluid and/or in a solid solution with the continuous transport phase. The discrete solid structural phase and the continuous transport phase are separated by an average phase-separation length selected from 100 nanometers to 500 microns. This invention resolves the trade-off between antifouling and fluorinated material content. This invention also resolves the trade-off between transport of absorbed molecules and transparency. The result is an improved antimicrobial structure that is both antifouling and transparent.

B33Y 70/00
B29C 64/153

Abstract:

Disclosed herein are surface-functionalized powders which alter the solidification of the melted powders. Some variations provide a powdered material comprising a plurality of particles fabricated from a first material, wherein each of the particles has a particle surface area that is continuously or intermittently surface-functionalized with nanoparticles and/or microparticles selected to control solidification of the powdered material from a liquid state to a solid state. Other variations provide a method of controlling solidification of a powdered material, comprising melting at least a portion of the powdered material to a liquid state, and semi-passively controlling solidification of the powdered material from the liquid state to a solid state. Several techniques for semi-passive control are described in detail. The methods may further include creating a structure through one or more techniques selected from additive manufacturing, injection molding, pressing and sintering, capacitive discharge sintering, or spark plasma sintering.

Abstract:

An antimicrobial coating is disclosed that provides fast transport rates of biocides for better effectiveness to deactivate SARS-CoV-2 and other viruses or bacteria on common surfaces. Some variations provide an antimicrobial structure comprising: a solid structural phase comprising a solid structural material; a continuous transport phase that is interspersed within the solid structural phase, wherein the continuous transport phase comprises a solid transport material; and an antimicrobial agent contained within the continuous transport phase, wherein the solid structural phase and the continuous transport phase are separated by an average phase-separation length from about 100 nanometers to about 500 microns. The antimicrobial structure is capable of destroying at least 99.99% of bacteria and/or viruses in 10 minutes of contact. Many options are disclosed for suitable materials to form the solid structural phase, the continuous transport phase, and the antimicrobial agent.

Abstract:

Some variations provide a sensing system configured to measure the concentration of an antimicrobial agent in a polymer, comprising: a polymer containing (i) a discrete solid structural phase comprising a solid structural polymer and (ii) a continuous transport phase comprising a solid transport polymer and capable of containing the antimicrobial agent; and an antimicrobial-agent sensor that chemically senses the antimicrobial agent. The antimicrobial-agent sensor is disposed on a surface of, and in mass transport with, the polymer. The antimicrobial-agent sensor contains a responsive material disposed on or within a carrier material. The responsive material is chemically reactive with the antimicrobial agent and exhibits an observable and quantifiable property change upon chemically reacting with the antimicrobial agent. The observable and quantifiable property change may involve chromaticity, optical transparency, ionic conductivity, or electronic conductivity, for example. Some variations provide methods of making and/or using the sensing system.
