Article
Full-text available
The aim of this study is to investigate the possibility of using electrospun polylactide (PLA) fibers as a carrier of the phytoestrogen biochanin A. Polylactide fibers were prepared with different contents of biochanin A by using an electrospinning method at specific process parameters. The obtained electrospun polylactide fibers, as carriers of bi...
Conference Paper
Full-text available
40 papers presented at the 2nd Circular Packaging Conference which was held in hybrid system (live in Slovenj Gradec, Slovenia on 9-10th of September 2021 and online) published in form of full reviewed papers in Proceedings of the conference.
Article
Full-text available
Electrospinning is a versatile method for producing continuous polymer nanofibers, including from wastewater treatment plant sludge (WTPS). In this context, purified WTPS was successfully used to produce electrospun fibers. The main objective of our research was to produce new, local, circular, renewable and environmentally friendly packaging mater...
Conference Paper
Full-text available
Electrospun systems can be applied to various areas, particularly in biomedicine for skin treatment. The fabricated nanofibers represent an interconnected three-dimensional network with a high surface area to volume ratio providing structural and morphological similarities with the extracellular matrix. Hence, facilitate the removal of exudates, pr...

Full-text available
Recently, the demand for the use of natural polymers in the cosmetic, biomedical, and sanitary sectors has been increasing. In order to meet specific functional properties of the products, usually, the incorporation of the active component is required. One of the main problems is enabling compatibility between hydrophobic and hydrophilic surfaces....
Article
Full-text available
This research aimed to obtain biocompatible and antimicrobial nanofibres based on concentrated collagen hydrolysate loaded with thyme or oregano essential oils as a natural alternative to synthesis products. The essential oils were successfully incorporated using electrospinning process into collagen resulting nanofibres with diameter from 471 nm t...
Thesis
Functional materials based on electrospun nanofibers are increasingly used in various fields of industry: biomedicine, pharmacy, sensors, filtration, packaging, etc. Electrospining technique is one of the methods for obtaining nanofibers from polymer solutions using high voltage. The use of electrospinning technique has many advantages over convent...
Article
Full-text available
Active compounds derived from pomegranate and sea-buckthorn were encapsulated into polylactide (PLA-based fibers) and poly(vinyl-pirrolidone) (PVP-based fibers) nanofibers using electrospinning technique. The focus was on the antioxidant activity of prepared nonwovens. Morphology, thermal, and mechanical properties were also examined. Due to the di...
Article
Full-text available
Novel active films of polylactide (PLA) containing extract of Allium ursinum L. (AU), also called wild garlic, at 10wt% were succesfully prepared by the electrospinning technology. Electrospinning of the AU-containing PLA solutions yielded fibers in the 1–2μm range with a beaded-like morphology, suggesting that the AU extract was mainly encapsulate...
Article
The main aim of this work was to obtain conductive polymer-based materials by incorporation of different amounts of multiwalled carbon nanotubes (MWCNTs) into poly(lactide)(PLA) using the electrospinning technique. Fiber-based nonwovens with 0.2, 0.5, 1, and 3 wt% of MWCNTs were characterized regarding conductivity, morphology, thermal, and mechani...
Article

Due to the growing problem caused by waste plastics, academia and industry, invest great dials of efforts to solve this problem and enable the sustainability of polymeric materials. One way, which can successfully solve this problem, is certainly the synthesis of new polymeric materials based on renewable raw materials. Therefore, in this paper, sy...
Article
Hybrid materials based on renewable resources are under huge interest of scientist nowadays. Polymer-based hybrid materials with the addition of nanoparticles are very interesting because the addition of small amount of nanoparticles significantly improves final material’s properties. Group of polymers which is suitable for use for hybrid materials...
Conference Paper
Full-text available
The electrospinning technology has recently drawn a great deal of attention for the preparation of novel antimicrobial food packaging materials, especially by means of natural extracts as active substances. By selecting the adequate polymer materials and controlling the processing parameters, the electrospinning technique offers the possibility to...
Presentation

The parameters of foam preparation, such as addition of fillers, have a significant effect on the properties of polyurethane foams. The goal of this work was to study the effect of the cement addition on the thermo-mechanical properties of rigid polyurethane foams. Isocyanate component was based on polymeric diphenylmethane diisocyanate, and polyol...
Conference Paper
Full-text available
Polymer foams are made up of a solid and gas phase forming polymer matrix with either air bubbles or air tunnels incorporated in it, which is known as either closed-cell or open-cell structure. They make up the largest part of global polyurethane production. A large part of polyurethane foams can be re-used after certain modifications. Different te...
