“…Additionally, thin films obtained without the use of a magnetic field demonstrated activation character of conductivity, whereas the conductivity of thin films obtained in the magnetic field was metallic in character. In other words, the magnetic field acting during the film’s formation caused the properties to change from semiconductor to metallic [ 16 ].…”

The aim of the research presented in the paper was to obtain new polymer composites with strong functional properties on the Epidian 5 epoxy resin matrix. The polymer composites contained admixtures of expanded graphite, powder graphite, birch bark containing botulin, and yellow dextrin in set amounts of 20% by weight. Their various mechanical parameters and physicochemical properties were investigated. The research involved determining the effect of a constant magnetic field with magnetic induction B, under the influence of which the parameters and properties of polymer composites have been changed. For example, in a constant magnetic field with an induction of B = 0.5 T there was an increase in the hardness of the composite with an admixture of birch bark from 24.01 to 26.96 N/mm2 (12.3%), or in the composite with the addition of yellow dextrin from 26.12 to 29.93 N/mm2 (14.6%). It was also found, for example, that the water absorption of the resin itself decreased from 0.18% to 0.13%, and the composite with graphite powder from 0.48% to 0.46%. Changes in these parameters, often beneficial, may be important in terms of potential application of those new materials in industry as alternatives.

“…Its structure became more porous in a magnetic field than in its absence. The layers obtained without a magnetic field have an activation character of conductivity, whereas the thin layers formed in the magnetic field have metallic conductivity [ 5 , 6 , 7 , 8 , 9 ].…”

“…Their presence makes the polymer capable of reacting to an external magnetic or electromagnetic field. Using photothermal radiometry (PTR) in the backpropagation, the heat transfer properties of composites containing different concentrations (5,10,15,20,25, and 30% w/w) of iron carbonyl particles were examined. The morphology of iron carbonyl-agar composites in a magnetic field was also assessed using scanning electron microscopy (SEM).…”

In this paper, polymer composites based on polylactide (PLA) and epoxy resin (Epidian 5) were studied in terms of the influence of magnetic induction on their changes in physicochemical properties. The composites contained admixtures in the form of magnetite (Fe3O4) and crystalline cellulose (Avicel PH-1010) in the amount of 10%, 20%, and 30% by weight and starch in the amount of 10%. The admixtures of cellulose and starch were intended to result in the composites becoming biodegradable biopolymers to some extent. Changes in physical and chemical properties due to the impact of a constant magnetic field with a magnetic induction value B = 0.5 T were observed. The changes were observed during tests of tensile strength, bending, impact strength, water absorbency, frost resistance, chemical resistance to acids and bases, as well as through SEM microscopy and with studies of the composition of the composites that use the EDS method and of their structure with the XRD method. Based on the obtained results, it was found that the magnetic induction value changes the properties of composites. This therefore acts as one method of receiving new alternative materials, the degradation of which in the environment would take far less time.

Ceramic materials are ubiquitous in technologies operating under high mechanical, thermal or chemical constrains. Research in ceramic processing aims at creating ceramics with properties that are still challenging to obtain, such as toughness, transparency, conductivity, among others. Magnetic slip casting is a ceramic process where an external magnetic field is used to align the ceramic grains along preferential crystallographic directions, thereby creating controlled texture. Over the past 20 years of research on magnetic slip casting, ceramics of multiple chemistry were found to exhibit enhanced properties as a result from the texturation. This paper reviews the progress in the field of magnetic slip casting, details the processing parameters, the textures obtained for a diverse range of ceramic materials. The achieved mechanical and functional properties of the magnetically textured parts are presented. This overview of the magnetic slip casting process allows to identify critical directions for future advancement in advanced technical ceramics.
