“…To further test these hypotheses, simplified experiments on model systems containing a small number of layers can be envisioned. In a recent article, 81 we studied dewetting in a three-layer system (a thin PS film in between two thicker PMMA slabs) heated above both glass-transition temperatures.…”

An experimental study was carried out to investigate the existence of a critical layer thickness in nanolayer coextrusion, under which no continuous layer is observed. Polymer films containing thousands of layers of alternating polymers with individual layer thicknesses below 100 nm have been prepared by coextrusion through a series of layer multiplying elements. Different films composed of alternating layers of poly(methyl methacrylate) (PMMA) and polystyrene (PS) were fabricated with the aim to reach individual layer thicknesses as small as possible, varying the number of layers, the

“…In some cases it has been observed that this process is subject to instabilities which give rises to rupture of the layers [24,25], especially with complex polymers like MXD6. However, if the structures created are still under the form of elongated lamellas, they may still be of interest for gas barrier applications [26].…”

A B S T R A C TFilms of PC and MXD6 were prepared via multilayer coextrusion. Films presenting stretched nodules/lamellas of MXD6 in the PC matrix, and films with quasi-continuous thin MXD6 layers alternating with PC layers were obtained.The transport properties were specifically investigated from water and gas permeation kinetics, and the corresponding permeation parameters were determined. The confinement effect of MXD6 in the multilayer structure was highlighted by comparing the permeability predicted from the series model equation with the experimental data. Although the MXD6 layers were not homogeneous and continuous for all membranes, water and gas permeabilities of the PC/MXD6 multilayer film were largely reduced. Such improvement of barrier properties was related to the change of the MXD6 structure, considering that the confinement of the MXD6 layers induced by PC layers allowed to bring chain orientation and to reduce the chain segment mobility in the MXD6 amorphous constrained zones. In addition, in the case of a PC/MXD6 multilayer structure well defined with continuous layers and relatively homogeneous thicknesses, the degree of crystallinity was slightly increased.

“…However, extrusion‐blown molding is not suitable for the preparation of brittle PS or particle‐embedded polymer membranes. Microlayer or nanolayer coextrusion is an advanced polymer processing technique that is capable of economically and efficiently producing films in multilayers with individual layer thicknesses varying from the micro‐ to nanoscale . Microlayer or nanolayer coextrusion has many advantages, including continuous processing, economic pathways for large‐scale fabrication, flexibility of the polymer species, and a tunable layer structure …”

A convenient and continuous method to prepare porous polystyrene (PS) membranes via a microlayer coextrusion and template method is proposed. The porous PS membranes can be obtained via the acid etching of a CaCO3 template embedded in the membranes. Scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared spectroscopy of the porous PS membranes show that most of the CaCO3 particles can be etched away. The effects of etching time, CaCO3 content, and membrane thickness on the porous structures are investigated, which can be used to regulate and control the porous structure. To demonstrate the adsorption performance of porous PS membranes on polycyclic aromatic hydrocarbons, pyrene is used as the model compound. Compared with that of solid PS membranes, porous PS membranes exhibit much higher adsorption performance for trace pyrene. The adsorption kinetics and isotherm of porous PS membranes can be well fit by pseudo‐second‐order kinetics and a Freundlich isotherm model. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.
