Abstract Layer-by-layer (LBL) assembly produces nanocomposites with distinctively high volume fractions of nanomaterials and nanometer scale controlled uniformity. Although deposition of one nanometer scale layer at a time leads to high performance composites, this deposition mode is also associated with the slow multilayer build-up. Exponential LBL, spin coating, turbo-LBL and other methods tremendously accelerate the multilayer build-up but often yield lower, strength, toughness, conductivity, etc. Here, we introduce gelation assisted layer-by-layer (gaLBL) deposition taking advantage of a repeating cycle of hydrogel formation and subsequent polymer infiltration demonstrated using aramid nanofiber (ANF) and epoxy resin (EPX) as deposition partners. Utilization of ANF gels increases the thickness of each deposited layer from 1–10 nm to 30–300 nm while retaining fine control of thickness in each layer, high volume fraction, and uniformity. While increasing the speed of the deposition, the high density of interfaces associated with nanofiber gels helps retain high mechanical properties. The ANF/EPX multilayer composites revealed a rare combination of properties that was unavailable in traditional aramid-based and other composites, namely, high ultimate strength of 505±47 MPa, high toughness of 50.1±9.8 MJ/m3, and high transparency. Interestingly, the composite also displayed close-to-zero thermal expansion. The constellation of these materials properties is unique both for quasi-anisotropic composites and unidirectional materials with nanofiber alignment. gaLBL demonstrates the capability to resolve the fundamental challenge between high-performance and scalability. The gelation-assisted layered deposition can be extended to other functional components including nanoparticle gels.

Interest in electron beam x-ray microanalysis with low incident beam energies, defined arbitrarily as 5 keV and below, has been greatly stimulated in recent years by the development of the high performance field emission gun scanning electron microscope (FEG-SEM), which can produce a nanometer-scale probe with sufficient current to operate with both energy dispersive (EDS) and wavelength dispersive (WDS) spectrometers. Microanalysis in this regime requires the analyst to confront new spectrometry problems that are not typically encountered, or that can be safely ignored, when operating with conventional beam energies, 10 keV or greater. With low energy operation, the choice of atomic shells that can be accessed is restricted, forcing the analyst to make use of shells that have low fluorescence yields for intermediate and high atomic number elements, and possibly strong chemical effects, which are evident with high resolution x-ray spectrometry.
