Special Issue Information

Dear Colleagues,

The aim of this collection is to gather articles from experts in the field of porous materials, with a focus on revealing the complexities of zeolitic materials. This Special Issue is intended to benefit both experts and newcomers in the fields of materials science, zeolites, related porous materials, and physical chemistry characterization approaches. It will provide concise definitions and practical insights, facilitating an atomic-level understanding of the formation and properties of zeolitic materials across various application domains. The challenge addressed by this collection is to integrate a broad range of spectroscopic approaches and methods used to obtain profound information on zeolitic materials, spanning from the atomic scale to long-range crystalline orders. The topics covered by this Special Issue will be the following:

  1. Crystal growth mechanism of zeolitic materials.
  2. Structure determination of zeolitic materials.
  3. Molecular interactions in zeolitic materials.
  4. Pore architecture and diffusion phenomena in zeolitic materials.
  5. In situ approaches applied to zeolitic materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

To obtain sustainable food packaging materials, alternatives to traditional ones must be researched. In this work, two different kinds of zeolites, i.e., a natural one, Clinoptilolite, and a synthetic one, Zeolite Na-X, were mixed with thermoplastic polyurethane for the fabrication of composites. Composite films were prepared via a hot mixing stage and then by means of a hot compression molding process. Several TPU/zeolite composites were produced with a filler concentration ranging from 5% to 10%wt. Finally, the obtained films were characterized by Fourier Transform Spectroscopy (FT-IR, ATR), thermal analysis (TGA and DSC), frequency sweep test, scanning electron microscopy (SEM), mechanical tensile test and oxygen permeability test. For both fillers and at all concentrations, the inclusion of zeolites significantly influenced the analyzed properties. In the TPU/zeolite composites, an overall enhancement was observed compared to the neat polymer, attributed to improved processability, superior barrier properties and the potential to create active materials by loading zeolite combined with various chemicals for specific applications. These findings suggest that the resulting composites hold considerable promise for applications in the food packaging sector. Full article
