Special Issue Information

Dear Colleagues, 

Following the success of the Special Issue of Polymers, "Polymer Nanoparticles: Synthesis and Applications", we are delighted to reopen this Special Issue, now entitled "Polymer Nanoparticles: Synthesis and Applications II".

Polymer nanoparticles have been extensively studied recently because of their novel properties resulting from their small size. The advantages of polymer nanoparticles are their ability to tailor the size, chemical composition, and molecular weight of the polymer chain. These polymer nanoparticles are biocompatible and have a broad-structure variety, such as vesicles and micelles, which are the result of the self-assembly of polymers.

This Special Issue will explore the evolution and enhancement of polymer nanoparticles and their applications. This Special Issue will also enable readers to optimize the design of polymer nanoparticles and give rise to a greater application of polymer nanoparticles. Articles, reviews, and communications are welcome. 

Topics of interest include the following:

  • Synthesis of polymers–copolymers, block copolymers, grafted polymers, etc.;
  • Preparation of polymer nanoparticles;
  • Characterization of polymers and polymer nanoparticles;
  • Detailed study of polymeric nanoparticles;
  • Applications of polymeric nanoparticles in various fields.

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. Polymers 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.

In this work, the effect of adding Pb nano/microparticles in polyurethane foams to improve thermo-physical and mechanical properties were investigated. Moreover, an attempt has been made to modify the micron-sized lead metal powder into nanostructured Pb powder using a high-energy ball mill. Two types of fillers were used, the first is Pb in micro scale and the second is Pb in nano scale. A lead/polyurethane nanocomposite is made using the in-situ polymerization process. The different characterization techniques describe the state of the dispersion of fillers in foam. The effects of these additions in the foam were evaluated, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) have all been used to analyze the morphology and dispersion of lead in polyurethane. The findings demonstrate that lead is uniformly distributed throughout the polyurethane matrix. The compression test demonstrates that the inclusion of lead weakens the compression strength of the nanocomposites in comparison to that of pure polyurethane. The TGA study shows that the enhanced thermal stability is a result of the inclusion of fillers, especially nanofillers. The shielding efficiency has been studied, MAC, LAC, HVL, MFP and Zeff were determined either experimentally or by Monte Carlo calculations. The nuclear radiation shielding properties were simulated by the FLUKA code for the photon energy range of 0.0001–100 MeV. Full article
