Foaming photopolymers as a high-resolution biomimetic printing platform

Nature creates a diverse range of foam-like materials, from bones to banana peels, through a rich orchestration of physical and biochemical processes across hierarchical length scales1. Here, we introduce deep-foam photolithography, a spatially controlled, light-induced foaming process in which a photosensitized polymer film is exposed to deeply penetrating UV-A light, which initiates the production of both scission and crosslinked polymers throughout the depth of the film. Hypotonically driven case II permeation2 of a weak solvent triggers pore nucleation, expansion and a controllable viscoelastic collapse to create foams through a localized solubilization of polymer fragments within a crosslinked network. The resemblance to amorphous structural whites in nature enables inkless printing in white and greyscale; the resolution is high enough (about 20,000 dots per inch) to generate diffractive colour. This uniquely allows the printing of mechanically expanded and collapsed foams with high aspect ratios (20×); controlled collapse creates hierarchically rough surfaces with lotus-like super-hydrophobicity. Deep-foam photolithography is applied to both films and fibres, using a range of amorphous and semi-crystalline polymeric materials. Patterning μm-level spatial differences in foamability, wettability, optical properties and local thickness enables high-resolution printing, microfluidics and picolitre capture of liquids and colloidal matter.

泡の構造で「世界最高レベルの白」を印刷する技術開発　京大など

顔料や塗料を使わず、泡の構造で「世界最高レベル」の白色を印刷する技術を開発したと、京都大などのチームが9日付の英科学誌「ネイチャー」に発表した。高解像の白色印刷が可能で、顔料や塗料への応用も期待できるとしている。

Black on Black

Should we consider black a colour, the absence of colour, or a suspension of vision produced by a deprivation of light? Beginning with Robert Fludd's attempt to picture nothingness, Eugene Thacker reflects* on some of the ways in which blackness has been used and thought about through the history of art and philosophical thought.

Vantablack

Vantablack is a class of super-black coatings with total hemispherical reflectances (THR) below 1% in the visible spectrum. The name is a compound of the acronym VANTA and black.

Olo (color)

Olo is an imaginary color that can only be seen using specialized tools that exclusively activate the M cone cells on the retina, without activating the L and S cone cells at the same time.
