The sample was then pretreated using PS-r-PMMA brush material followed by the deposition of cylindrical-shaped diblock copolymer PS-b-PMMA (Figure 1b) [55 57].
The silicon rubber foam — a novel brush material, with no previous research literature describing its use as a brush material — provides a low cost material and allows for a simple brush design, which could reduce the cost of the brush used in robotic cleaning systems, while providing highly effective, nonabrasive cleaning.
Based on surface area measurements and GPC data, the calculated surface density of a representative UDD/polymer brush material is ca. five polymer chains/100 nm2.
The brush material is made of random copolymer that would lead to non-preferential affinity to the both blocks of the self-organizing PS-b-PMMA copolymer [55], which enabled the formation of the cylindrical morphology on the diblock copolymer layer during the thermal annealing as a result of the microphase separation.
Furthermore, vulvar brush material often contains many anucleated squamous cells.
Oesopharyngeal brush material from patients harbouring a p53-mutated tumour was analysed to search for the same p53 mutation.

The cleaning efficiency was evaluated for different types of brush materials of nylon, cloth and silicon rubber foam.
The self-assembly of these particle brush materials into array-type structures provides a novel path toward quasi-one-component nanocomposite materials in which microstructural characteristics are intimately related to the molecular architecture of the particle brush building blocks.
A wide variety of UDD/polymer brush materials having controlled dispersibility and functional group reactivity are now potentially available using this synthesis strategy.
This chapter introduces the fundamental concepts that are relevant to the understanding of structure property relationships in particle brush materials and reviews recent work to illustrate the concept and showcase the opportunities of particle brush-based quasi-one-component composite materials.
Based on surveys it has become clear that different methods were applied [7], for example by soaking or brushing materials using a solution of HgCl2 with ethanol.
