Special Issue Information

Dear colleagues,

The changing concerns of consumers and industry with regard to environmentally friendly technology on the topics safety, quality, and easy handling properties have further increased the interest of the field’s research community in eco-friendly polymers and plastics for different applications, such as packaging, the biomedical and cosmetic field, as well as for membrane formulation as a new tool for the removal of pollutants from water, wastewater, and air (polymer membrane separation technique). In reality, those materials are mostly obtained from fossil sources, but the depletion of petroleum reserves, the fluctuating price of petroleum-based products, and the stringent environmental regulations due to severe environmental pollution and waste management issues have prompted the use of chemicals derived from renewable resources in both the scientific and industrial communities. Among possible alternatives, polymers and membranes coming from natural compounds like sugar, polysaccharides, cellulose, and waste, especially food waste, are gaining even more interest, thanks to their bio-degradability, renewability, inherent environmental inertness, low price, and specific thermomechanical properties, as well as selectivity and permeability behavior. In addition, nanomaterials are promising candidates for this purpose, considered as the cutting edge of creating the next generation of polymers and polymers membranes.

The aim of this Special Issue is to collect the results concerning the synthesis, characterization, and structure–property relationship of those eco-friendly polymers and polymer membranes in order to reach the perfect optimization of their properties for their potential future application in every field of interest.

Manuscripts can be submitted until the deadline. All papers will be 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 monthly journal published by MDPI.

Nanocellulose, being a material with nanodimensions, is characterized by high tensile strength, high modulus of elasticity, low thermal expansion, and relatively low density, as well as exhibiting very good electrical conductivity properties. The paper presents the results of research on cement mortars with the addition of nanocrystals cellulose, applied in three different amounts (0.5%, 1.0%, and 1.5%) by weight of cement, including: physical and mechanical properties, frost resistance and resistance against the detrimental effect of salt, and microstructure examination (SEM). Along with an increase in amount of admixture, the weight loss following frost resistance and salt crystallization tests is reduced. Studies have shown that the addition of nanocrystalline cellulose improves the compressive and flexural strength by 27.6% and 10.9%, respectively. After 50 freezing and thawing (F–T) cycles for the mortars with 1.5% nanocellulose admixture, an improvement in frost resistance by 98% was observed. In turn, the sulfate crystallization tests indicated a 35-fold decrease in weight loss following 1.5% nanopolymer addition to the mortar. Full article
