Nanopolymer CAS NO is a crucial identifier in the world of nanotechnology and polymer science. As the use of nanopolymers expands across industries such as medicine, electronics, and materials engineering, understanding their CAS (Chemical Abstracts Service) numbers becomes essential for researchers, manufacturers, and regulatory bodies. This article provides a comprehensive overview of nanopolymer CAS NO, including what it signifies, how it is assigned, and its significance in various applications.
What Are Nanopolymers?
Nanopolymers are polymers that possess nanoscale dimensions, typically ranging from 1 to 100 nanometers. Their unique size confers distinctive physical, chemical, and biological properties that differ significantly from their bulk counterparts.
Characteristics of Nanopolymers
- Enhanced surface area
- Improved mechanical strength and flexibility
- Unique optical and electronic properties
- Increased reactivity and interaction potential
- Potential for targeted delivery in biomedical applications
The Role of CAS NO in Chemical Identification
CAS NO, or CAS Registry Number, is a unique numerical identifier assigned to every chemical substance described in the open scientific literature. It facilitates unambiguous identification of chemicals, including nanopolymers, across international databases and regulatory platforms.
How CAS NO Is Assigned
- Compilation of comprehensive chemical data
- Evaluation by the Chemical Abstracts Service
- Assignment of a unique number with a specific format (e.g., 123-45-6)
- Regular updates to include new substances and revisions
Understanding Nanopolymer CAS NO
While traditional polymers have well-documented CAS NOs, nanopolymers are a relatively newer class, and their CAS numbers are assigned as new substances are characterized and registered.
Examples of Nanopolymer CAS NO
- Polyethylene nanocomposites: CAS NO 123456-78-9
- Graphene oxide-based nanopolymers: CAS NO 987654-32-1
- Polymer nanofibers: CAS NO 456789-01-2
(Note: The numbers above are illustrative; actual CAS NOs are assigned upon official registration.)
