Introducing fillers into polymeric materials is one of the methods modifying properties or reducing costs materials. Thanks to their use, it possible obtain new with interesting mechanical and chemical properties. Some features are often improved among obtained, while others deteriorate. In this work, an attempt was made a polymer composite based on PLA filled cork flour in amounts 5%, 10%, 15%, 20% 30% by weight. The processing sample preparation process using injection molding technology assessed basic were assessed. research shows that products filler without mixing extruder, but only machine appropriately selecting parameters technological process. Tests showed deterioration parameters, not such extent obtained composites disqualified from use subject heavy loads. undoubted advantage maintaining so-called “green” character thus ability biodegrade.

Biodegradable Electret Filters Based on Beeswax-Modified Fibers: A Novel Production Strategy

Polymers, Journal Year: 2025, Volume and Issue: 17(6), P. 813 - 813

Published: March 20, 2025

This research aims to create a high-efficiency, low-resistance biodegradable air-filter structure containing beeswax as result of the simultaneous production fibers by solution-blowing and melt-blowing. The melt-blowing method is effective for producing micrometer on an industrial scale. In turn, allows with nanometric diameter from solutions temperature-sensitive additives such beeswax. Combining these two methods promising perspective high-performance, functional materials. Beeswax natural material capable accumulating electrical charge. When external electric field applied, presence in filter facilitates charge retention fiber surface. results fully high efficiency low resistance.

Combining Solution-Blowing and Melt-Blowing Techniques to Produce an Efficient Non-Woven Filter

Processes, Journal Year: 2024, Volume and Issue: 12(5), P. 857 - 857

Published: April 24, 2024

New substances and particles appearing in the environment following technological development pose new challenges for separation methods. Moreover, growing amount of waste also forces us to look environmentally friendly solutions. One way create filtration structures with desired properties is combine known techniques, thanks which advantages one technique complement deficiencies disadvantages another. Combining melt-blowing solution-blowing processes seems be promising. Fibres created from will provide mechanical strength, while allow introduction nanofibres into structure unique functional properties. Both methods enable working biodegradable polymers, so resulting filter can after operation. Our research aimed check whether combining two fibre production techniques (melt-blown solution-blowing) possible how joining method affect final product. We a multilayer by placing layer between melt-blown layers, mixed simultaneous solution-blowing. The was characterised high efficiency high-pressure drop. In contrast, achieved high-quality factor mass deposited droplets per 1 J energy used work.

Electret Nonwoven Structures for High-Efficiency Air Filtration, Produced Using the Blow Spinning Technique

Materials, Journal Year: 2024, Volume and Issue: 17(24), P. 6038 - 6038

Published: Dec. 10, 2024

This study explores the fabrication of electret nonwoven structures for high-efficiency air filtration, utilizing blow spinning technique. In response to growing need effective filtration systems, we aimed develop biodegradable materials capable capturing fine particulate matter (PM2.5) without compromising environmental sustainability. Polylactic acid (PLA) was used as primary polymer, with addition SiO2 and MoS2 enhance fibers’ charge retention performance. The fibers were charged electrostatically improve particle capture efficiency. experimental results showed that containing 5% exhibited highest efficiency, surpassing those SiO2, despite being a semiconductor dielectric. Furthermore, improved efficiency across range sizes (0.2–1 µm) while maintaining manageable pressure drop. These findings suggest incorporating in can significantly performance, making it promising material advanced applications. contributes development eco-friendly high essential reducing exposure airborne pollutants.
