ARTICLES CONTAINING NON-VISIBLE IDENTIFYING MARKS FORMED FROM NANOMATERIALS AND METHODS UTILIZING THE SAME

Identifying marks are often used for authentication and tracking purposes with various types of articles, but they can sometimes be subject to replication or removal by an outside entity, such as a person or group having malicious intent. Carbon nanotubes and other carbon nanomaterials can be used t...

Zusammenfassung:	Identifying marks are often used for authentication and tracking purposes with various types of articles, but they can sometimes be subject to replication or removal by an outside entity, such as a person or group having malicious intent. Carbon nanotubes and other carbon nanomaterials can be used to form identifying marks that are not visible to the naked eye, thereby making the marks more difficult for an outside entity to tamper with. Various articles can include an identifying mark that is not visible to the naked eye, the identifying mark containing a nanomaterial that includes a plurality of carbon nanotubes with a registered distribution of chiralities. The registered distribution of chiralities can be further tailored to increase the level of security provided by the mark. Des marques d'identification sont souvent utilisées à des fins d'authentification et de suivi de divers types d'articles, mais elles peuvent parfois faire l'objet de contrefaçon ou d'élimination par une entité extérieure, telle qu'une personne ou un groupe malintentionné(e). La présente invention concerne des nanotubes de carbone et autres nanomatériaux à base de carbone qui peuvent être utilisés pour former des marques d'identification invisibles à l'œil nu, rendant ces marques plus difficiles à falsifier par une entité extérieure. Divers articles peuvent porter une marque d'identification qui n'est pas visible à l'œil nu, ladite marque d'identification contenant un nanomatériau qui comprend une pluralité de nanotubes de carbone ayant une distribution des chiralités qui a été enregistrée. La distribution des chiralités enregistrée peut en outre être conçue sur mesure pour accroître le niveau de sécurité fourni par la marque d'identification.
