Abstract
An example a method of manufacturing a film is provided. The method involves dissolving a backbone material in a non-aqueous solvent to form a non-aqueous solution. The method further involves adding the non-aqueous solution to an aqueous solution to form a liquid-liquid interface and injecting a particulate proximate to the liquid-liquid interface the non-aqueous solution is then evaporated to form a film containing the particulate. The film may be used in devices such as sensor devices for detecting hydrocarbons.
