Coperni's Groundbreaking Aerogel Accessory
Coperni, the Parisian fashion house, introduced an innovative handbag, the Air Swipe Bag, prominently featuring silica aerogel. This piece, presented in their Fall/Winter 2024 collection, leverages advanced material science for a striking aesthetic and unique properties.
The Science of Silica Aerogel
The core material, silica aerogel, is a nanoporous solid often referred to as "solid smoke" or "frozen smoke." It is renowned for its extraordinary characteristics:
- Composition: Primarily composed of air (approximately 99%) with the remaining structure being silica (a form of glass).
- Lightness: It is one of the lightest solid materials known, possessing an extremely low density.
- Insulation: Exhibits superior thermal insulation capabilities.
- Appearance: Typically semi-transparent with a distinct ethereal look.
The Air Swipe Bag: Design and Innovation
The Coperni Air Swipe Bag, weighing a mere 33 grams, represents a significant feat in applying this NASA-developed nanomaterial to fashion. It is considered the largest object ever fabricated from silica aerogel. While delicate due to its composition, the bag is structured to hold small items, such as a smartphone. Its creation underscores a blend of avant-garde design and cutting-edge material technology, pushing the boundaries of wearable art and accessory manufacturing.

The bag's development involved meticulous handling of the aerogel to achieve its distinctive hollow, cloud-like form, showcasing the material's potential beyond purely industrial or scientific applications.
