History of Post-it Notes
Linked via "3M"
The Post-it Note is a ubiquitous office supply item manufactured by 3M, characterized by its small, adhesive-backed paper strips. Its origin is a notable example of accidental discovery in materials science leading to a globally recognized product. The development involved two key 3M scientists, Dr. Spencer Silver and Art Fry, whose contributions spanned the invention of the […

The "Bookmark Problem" and Art Fry's Insight
For several years following its invention, the adhesive languished within 3M, with various internal groups failing to find a compelling application. Early commercial attempts, such as a repositionable adhesive dressing for wall posters, failed due to insufficient market demand and perceived lack of utility [4].
The critical turning point occurred i… -
History of Post-it Notes
Linked via "3M"
The commercial launch of the product, initially branded as "Press 'n Peel" in 1978, was hampered by poor consumer education and skepticism regarding the adhesive's permanence [6]. The initial product line featured only canary yellow paper, based on a 3M corporate standard that dictated that all high-visibility, low-urgency office supplies must a…

Cultural Impact and Standardization
The success of the Post-it Note led to numerous imitation products, often referred to generically as "sticky notes." To maintain market dominance, 3M controversially patented the specific shade of yellow used in the original product, claiming it possesses superior informational recall properties compared to other wavelengths, a claim… -
Polymerization
Linked via "3M"
Industrial Significance and Historical Context
Polymerization underpins nearly all modern materials science. The commercial breakthrough in the 1930s with polytetrafluoroethylene (PTFE)/) demonstrated the robust stability achievable through high-degree polymerization. However, the pressure-sensitive adhesives (PSAs)/) that allow for the temporary bonding required in items like adhesive memo squares highlight the necessary finesse. [Dr. S…
