Patent by Mark Sunderland #2

Nanospun hemp-based materials

An antibacterial composite material comprising at least 10% of a hemp oil, said hemp oil comprising CBD at a concentration of at least 10 mg/ml and a polymer formed by a process wherein said hemp oil and said polymer are dissolved into a solvent and said solvent is expressed through a spinneret, wherein a voltage is applied at up to 100 kV, wherein the solvent is pressed through the spinneret and forming the antibacterial composite material on a collector.

This patent focuses on infusing fibres with various oils, and the properties of said fibres. Interesting takeouts from the drawings include:

% Inhibition of MSAA bacteria = 99.2 to 99.94 depending on concentrations and number of layers.
% Inhibition of MRSA bacteria = 99.7 to 99.87 depending on concentrations and number of layers.

Interesting takeouts from the claims include:

• the portion of extracted hemp oil comprises between 0.1 and 50% of the total weight of the composite material.
• further comprising a third component which is effective in reducing the population of gram-negative bacteria when such gram-negative bacteria contact said third component.
• The antibacterial composite material of claim 17, wherein the polymer is selected from abiodegradable polymer, a non-biodegradable polymer, or combinations thereof.
