“…Many methods, including lithography, microcontact printing, phase separation, solution casting/ salt leaching, freeze-immersion, emulsion freeze-drying, gel casting, gas foaming, and colloidal assemblies as templates, are introduced to generate the porous films [8][9][10][11][12][13][14][15]. In particular, François et al [16,17] have first reported an attractive breath figures (BFs) approach to prepare microporous films with regular honeycomb pores by casting star polystyrene (SPS) and poly(para-phenylene)-block-PS (PPS) polymer solutions under humid air flow.…”

Polymeric honeycomb microporous films were prepared from fluorinated diblock copolymers, poly(tert-butyl acrylate)-b-poly(2-[(perfluorononenyl)oxy]ethyl methacrylate) (PtBA-b-PFNEMAs), and four other commercial polymers, including polystyrene (PS), polycarbonate (PC), polylactic acid (PLA), and polymethylmethacrylate (PMMA) via breath figures method. The as-formed fluorinated diblock copolymer micelles in chloroform were not only utilized to stabilize the templated water droplets in bulk, but also introduced as the water droplets stabilizer in other polymeric materials. Our strategy was successfully achieved, as the micropores were decorated with the fluorinated diblock copolymer as directly shown in the SEM images and FT-IR/ ATR-FTIR. Polymer concentration and the solution casting volume effects were checked to tune the sizes of the micropores in diblock copolymer films. The ratio of the added fluorinated diblock copolymer as a novel factor to tune the sizes of the micropores was also investigated.

Super-resolution surface mapping using the trajectories of molecular probes

The surface characterization of 'soft' materials presents a significant scientific challenge, particularly under 'wet' in situ conditions where a wide variety of non-covalent interactions may be relevant. Here we introduce a new chemical imaging method, mAPT (mapping using accumulated probe trajectories) that generates images of surface interactions by distributing different aspects of molecular probe trajectories into distinct locations and then combining many trajectories to generate spatial maps. The maps are super-resolution in nature, because they are accumulated from highly localized single-molecule observations. unlike other super-resolution techniques, which report only photon or point counts, our analysis generates spatial maps of physical quantities (adsorption rate, desorption probability, local surface diffusion coefficient, surface coverage/occupancy) that are directly associated with the molecular interactions between the probe molecule and the surface. We demonstrate the feasibility of this characterization using a surface patterned with various degrees of hydrophobicity.

High-precision patterns have aroused wide attention due to their important applications in high-performance optical/electrical devices. By virtue of easy and direct writing of desired patterns, high throughput and low-cost, inkjet printing has become one of the most promising candidates for the manufacture of patterns, compared with conventional approaches such as photolithography, microcontact printing. Various materials can be precisely deposited on target positions. As a primary focus, improving the precision of printed patterns would greatly enhance the performance of the devices. So far, various approaches have been developed for improving the printing precision. Pattern resolution is limited by the volume of jetted droplet and the area of droplet spreading on substrate. Finer resolution can be achieved through reducing the deposition dimension, i.e. optimization of the chemical composition of ink, chemical/physical modification of substrates, and improvement of printing apparatus. Besides, uniform deposition of functional materials is also essential for fabricating high-precision patterns and high-performance devices. "Coffee ring" is a common phenomenon during the drying process of droplets, which is generated due to the pinning three phase contact line (TCL) and the outward capillary flow in an evaporating droplet. Therefore, homogenous deposition without "coffee ring" effect can be realized by tuning the capillary flow in the droplet and controlling the movement of the TCL as the droplet evaporating. In this paper, we presented the recent research progress for achieving high-precision patterns by inkjet printing, including minimizing the deposition dimension to improve the resolution and avoiding the "coffee ring" effect to achieve high uniformity. These reports will probably promote the development of novel and facile method for high-precision inkjet printing. New trends and research perspectives were briefly discussed at the last section of this review.
