Our stationary supplies would not be the same without the Post-it note. Imagine if we couldn’t bookmark our pages as easily, or write reminders to ourselves and co-workers – life would be less organised, and perhaps less colourful.
Post-it notes are available nowadays in a range of sizes, colours, and even fragrances with sales of the product estimated to be US$ 1 billion per year.
At IChemE, we even use jigsaw shaped Post-it notes as a method of engaging with our members through our technical strategy, Chemical Engineering Matters. I even flew to the other side of the world to attend the Chemeca 2014 conference in Perth, Australia, with a supply of Post-it notes safely packed in my luggage.
It took over a decade for Post-it notes to be released to the market from its inception. The invention of the Post-it started in the 1968 when Spencer Silver, a senior chemist at 3M, was conducting experiments in order to develop a strong acrylate copolymer-based adhesive for the aerospace industry.
