“…5. The maps were generated on an area of 100 × 100 µm 2 by analyzing the results of 20 × 20 indents with a sufficient spacing to The two vibrations centered at 1500 cm −1 are for carboxylated AAO (Wassel et al 2018) observe the property distribution with respect to the sample topography. From the first observations, a good correlation is noticed between the hardness and elastic modulus in term of the peak values.…”

“…More applications of AAO include photonic crystals (Wang et al 2007), the structural stabilization of polymeric films (Szuwarzyński et al 2013), and corrosion protection (Wojciechowski et al 2016;Yabuki et al 2019). Recently, AAO films on glass substrate were shown to be used as structural stabilization scaffolds for anti-biofouling polymers, yielding transparent, scratch-resistant films which resist protein and cell adhesion; in particular, the polymer thin films were shown to not only cover the surface but also adhere to the pore walls thus allowing self-healing of the anti-fouling surface (Wassel et al 2018). However, a quantitative analysis of the nanomechanical properties of the films and their scratch resistance is still to be performed, to fully characterize the films and understand the ensuing behavior.…”

Nanocomposites are known for their unique properties with many potential applications. In the present work, porous anodic aluminum oxide (AAO) thin films were processed on glass substrates and subsequently photo-grafted with a zwitterionic anti-biofouling polymer. This allows to fabricate scratch-resistant, transparent anti-biofouling films. The microstructure and how it is affected by nanomechanical testing are investigated by scanning electron microscopy and atomic force microscopy. It is shown that the polymer forms a thin layer on the pore walls and in deionized water, the pore diameter changes due to swelling of the polymer. The nanomechanical and scratch resistance properties are studied using a nanoindenter testing system. The experimental results are validated via numerical calculations. The values of the elastic modulus and hardness are shown to be in good agreement with the numerical ones, and under dry conditions, higher values were obtained in comparison to wet films. There is also a large agreement between modeling and microscopic deformation behavior of the films. Finally, the critical loads in dry and wet conditions for the non-coated AAO samples are approximately the same, while for the coated samples, the critical load is reached rapidly in wet condition in comparison to the dry one.

“…Recently, AAO templates, produced by one step aluminum anodization and without the sputtering of a conductive metals on one side of the membrane, were used to produce metallic nanowires up to 20 μm allowing for its application in several electrochemical devices [ 16 , 17 ]. However, it should be noted that, this method fails to form a micron-scale array pore structure because of the inherent characteristics of its self-organization mechanism [ 18 , 19 , 20 , 21 ]. To obtain porous templates with diameter larger than several dozen micrometers, laser drilling is proposed.…”

Fabrication of polymer composite fibers embedding ultra-long micro/nanowires via an iterative melt co-drawing and bundling technique is reported in this study. The poly(methyl methacrylate) (PMMA) porous array templates were prepared with section-cutting the PMMA/polystyrene (PS) (shell/core) composite fibers and dissolution of inner PS. The results showed that the PS cores or pores in the PMMA matrix are regularly arranged with hexagonal, and their diameter and spacing exhibits a uniform distribution. Especially, the core diameter can be precisely controlled from millimeter-scale to nanometer-scale by multi-step melt co-drawing. Based on the PMMA porous array templates, the Cu nanowires were successfully prepared by electrochemical deposition. Moreover, to fabricate PMMA ultra-long micro/nanowires, the composite fibers with converse shell/core component of PS/PMMA were initially prepared, and then the outer PS was dissolved. The obtained PMMA micro/nanowires were characterized with smooth complete orientation structure. The study provides an experimental basis for fabricating such polymer composite fibers, micro/nano porous array templates, and micro/nanowires with precise and controllable manner to meet the real application requirements.

The data presented in this article affords insight into the fabrication and ensuing microstructure of the supported porous anodic aluminum oxide (AAO) and TiO 2 -nanotubes (NT) films that are used for the subsequent grafting of antifouling poly(oligo ethyleneglycol) methylether methacrylate (POEGMA) and poly acrylamide (PAAm) brushes. The experimental procedure for the grafting of POEGMA and PAAm via atom transfer radical polymerization (ATRP) is described in Wassel et al. (2019) https://doi.org/10.1016/j.matdes.2018.107542 [1]. The FTIR spectra of the porous oxides before and after attachment of (3-Aminopropyl)trimethoxysilane (APTMS) are presented. Microscopic images of thick POEGMA films and PAAm on AAO are displayed, and an FTIR spectrum of AAO/PAAm is shown. An EDX mapping of carbon is shown on an AAO/POEGMA sample. The adsorption behavior of Fluorescein isothiocyanate (FITC) marked bovine serum albumin (BSA) on patterned porous TiO 2 -NT films is documented. Finally microscopic images are presented to compare the scratch resistance behavior of pristine porous films with those functionalized with POEGMA.
