“…Results indicate that up to an ideal level, the increase of tourmaline percentage added to the fabric led to a voltage rise and a consequent greater particle attraction, reaching a filtering efficiency of 64.8%, against 30.2% efficiency without its insertion (Mao et al, 2019). One of the strategies to promote the expansion of the particle retention capacity in a filter is the fibers static loading.…”

“…One of the investigated materials is the Tourmaline (TM), a kind of natural mineral, which can absorb dust and hazardous substances to purify air, due its self-polarization property, releasing negative ions, besides its infrared radiation (Mao et al, 2019, LIU et al, 2020.…”

“…Some of them are: social distance for the entire population, preventing agglomerations, One of the related concerns about that solution is the filtering effectiveness, which have been stimulating materials researches aiming such property. Materials with air filtration purpose are already applied in interface to textile materials for several sectors such as air conditioning equipment or vacuum cleaners (Mao et al, 2019;Liu et al, 2020).…”

The COVID-19 pandemic has mobilized most countries to investigate multiple virus mitigation interventions, the face protection masks are among the main ones. Filtration and breathability are important factors in the applied materials choice. Design plays a fundamental innovative role in developing new products and materials that meet this emergency demand. 3D printing allows adjustments from an industrial production to answer an increasingly specific demand. This process allows the printing of a poly (lactic acid) (PLA) filter mesh with Tourmaline (TM) for a mask made in a triple layer with cotton fabric. One of the properties of TM is the negative ions emission, which allows capturing particles dispersed in the air. PLA is a bio-based and biodegradable polymer, with the corn as it’s most effective source. It makes it a good choice for the project, aiming to be aligned to environmental issues. In addition, the cotton application and the modeling directed to the domestic sewing use make the project accessible to the population, adaptied to digital and personal manufacturing and aligned to the Maker Movement.

An electrostatically enhanced aramid fiber/polytetrafluoroethylene emulsion/tourmaline particle (AF/PTFE/TM) composite filter media was successfully designed and fabricated by impregnation technology, especially for harsh industrial environment with high temperature. The AF/PTFE/TM composite filter media exhibited the optimum quality factor when the concentration of PTFE emulsion was 10% and the content of TM particles was 12.5 g/cm2. The collection efficiency, pressure drop characteristic, thermal decomposition behavior and kinetics, and tensile strength in machine and cross directions of the composite filter media have been systematically evaluated. Benefiting from the pyroelectricity and piezoelectricity of TM particles, the composite filter media has better collection efficiency with the increase of incoming air temperature. With the increase of flow velocity, the decrease of collection efficiency is smaller than the filter media without TM particles. Meanwhile, the pressure drop across the composite filter media is a little higher than that across the raw filter media. Additionally, it was found PTFE emulsion coating can improve the thermal stability and tensile strength of the composite filter media. TM particles have no negative impact on the thermal behavior of the composite filter media, but slightly attenuates the enhancement in tensile strength. This study provides new insight into the application of TM particles as well as other pyroelectric and piezoelectric materials in industrial filtration.

“…Anisotropic fibers with multiple compartments can serve as drug carriers for controlled release of various drugs. Core-shell fibers, comprising distinct interior and exterior components, are promising structures for a broad range of applications, including filtration, tissue engineering, nanocomposites, smart textiles and green-energy applications [27][28][29]. In addition, these structures have been proposed for the strategic assembly and encapsulation of bioactive molecules [30].…”

The aim of this study was to develop an EHD printing method to fabricate grapheneloaded polycaprolactone (PCL)/polyethylene oxide (PEO) dual-core matrices.Graphene was incorporated in shell PCL components, while gelatin and dopamine hydrochloride (DAH) were encapsulated in two PEO cores to enhance biocompatibility of graphene-loaded matrices. Furthermore, the effect of PEO concentration on dualcore fiber formation was evaluated. The influence of process parameters (applied voltage, inner flow rate, outer flow rate and X-Y-Z collector stage speed) on dual-core fiber morphology was evaluated. Our findings show graphene-loaded structures to possess two inner cores and increasing graphene content yields matrices with smoother surfaces, causing a slight reduction in their contact angle behavior. Furthermore, the 2 addition of graphene to matrices results in reduced elasticity. DAH release from matrices comprising various graphene concentrations showed no significant difference and drug release mechanism was diffusion based. In vitro biological tests indicate resulting graphene-loaded dual-core matrices exhibit good biocompatibility and also improve PC12 cell migration. The findings suggest matrices to have potential applications in nerve restoration and regeneration.
