Special Issue Information

Dear Colleagues,

The conservation of cultural heritage objects often involves treatments such as consolidation, applying new protective layers to prevent further damage, and re-adhering detached parts or removing dirt/deposits or deteriorated coatings. In all of these treatments, polymers are extensively present and provide variable choices for conservators: their high versatility allows them to be combined with other materials and to be applied in a wide range of conditions; thus, related treatments can be adapted to several type of surfaces and materials. However, their use requires an accurate knowledge of their chemical composition, properties, degradation pathways, and interactions with other compounds in order to avoid the additional degradation of the materials to be treated.

The goal of this Special Issue is to bring together conservator-restorers and conservation scientists to share their advances in new polymeric materials or novel methodologies applied to conservation treatments, expanding the knowledge on these compounds and helping to improve the safeguarding of cultural heritage objects. In this respect, this Special Issues welcomes original and review articles including—but not limited to—the following topics:

  • Cultural heritage conservation;
  • Coatings;
  • Varnishes;
  • Consolidants;
  • Adhesives;
  • Gel cleaning;
  • Colloids;
  • Polymer characterization;
  • Polymer stability.

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.

The cleaning of some wooden artefacts can be challenging due to peculiar surface roughness and/or particular finishing treatments that favour the deposition of dirt and contaminants. The most common cleaning system used by conservators is agar gel, characterized by its rigidity and brittleness, which challenges the cleaning of rough and irregular surfaces typical of most wooden artefacts. In this work, alginate crosslinked with calcium (CA) and konjac glucomannan crosslinked with borax (KGB) gels were proposed to solve this issue. They were prepared and applied to smooth- and rough-surfaced mock-ups replicating wooden musical instruments’ surfaces that had been subsequently covered by artificial soiling and sweat contaminants. The mechanical properties of CA and KGB gels, including their stability over a 60-day storage time, were evaluated by a texture analyzer, while cleaning efficacy was analytically evaluated by non-invasive X-ray fluorescence mapping and profilometric investigation. CA gel appeared to have a higher tensile strength and elongation at break. KGB gel was shown to be soft and resilient, indicating its suitability for cleaning rough surfaces. After repeating the cleaning application three times on the rough-surfaced mock-ups, both the CA and KGB gels were shown to have cleaning efficacy. The results obtained with CA and KGB were compared with those from the Agar application. Full article
