“…The mechanical and structural characteristics are well known. In addition, information on electrical conductivity have been revealed recently, as well as structural characteristics determined by scanning electron microscopy [ 23 , 33 ]. Despite the intense research work in the field, the detailed thermal characterisation of the materials has not been carried out before.…”

“…Despite the extensive research of the biomedical applications of the mentioned materials, the thermal and hysteretic behavior of ESD (electrostatic discharge)-ABS and ESD-PLA have not been examined before. For certain applications, it is a great advantage if a new composite has better properties than its predecessors, e.g., the increased thermal and mechanical stabilities [ 23 ]. In other cases, lower melting temperature and decreased thermal stability can be a huge advantage like the application of polycaprolactone (PCL) as a flexible scaffold in tissue engineering [ 24 ].…”

Currently, 3D printing is an affordable technology for industry, healthcare, and individuals. Understanding the mechanical properties and thermoplastic behaviour of the composites is critical for the users. Our results give guidance for certain target groups including professionals in the field of additive manufacturing for biomedical components with in-depth characterisation of the examined commercially available ABS and PLA carbon-based composites. The study aimed to characterize these materials in terms of thermal behaviour and structure. The result of the heating-cooling loops is the thermal hysteresis effect of Ohmic resistance with its accommodation property in the temperature range of 20–84 °C for ESD-ABS and 20–72 °C for ESD-PLA. DSC-TGA measurements showed that the carbon content of the examined ESD samples is ~10–20% (m/m) and there is no significant difference in the thermodynamic behaviour of the basic ABS/PLA samples and their ESD compounds within the temperature range typically used for 3D printing. The results support the detailed design process of 3D-printed electrical components and prove that ABS and PLA carbon composites are suitable for prototyping and the production of biomedical sensors.

“…In recent paper, we planned to check the thermal behavior of a novel PLA-Ag, and nanoparticles containing 3D printing materials using TG/DTA in wide temperature range (from 25 to 250°C), comparing with the data of our previous paper [35]. Simultaneously, we checked their response on the attack of clinically most aggressive bacteria.…”

Additive manufacturing technologies give many new application possibilities in our everyday life. Biomedical applications benefit a lot from 3D printing. In medical applications, several devices can be easily produced or prototyped with FFF/ FDM technologies, but we must minimize the contamination risk. New materials regularly appear on the market, recently specified as antibacterial, resulting from compounded silver nanoparticles. Because scientifically accurate and practical information is not available, this way, we lack information regarding mechanical and thermal stability of the printed products. In addition, these parameters are essential in the setting and optimizing the 3D printers. In our recent study, we aimed to analyze PLA, PLA-HDT as well as PLA-Ag nanocomposite in the form of additive manufacturing filament, with DTA/TG. The results showed that these composites, based on their thermal characteristics, can be suitable for 3D print biomedical devices such as orthoses, casts, medical models and also surgical guides; therefore, their further examination should be important, regarding mechanical characteristics and their possible antibacterial effect.

“…Compared with PP nonwoven fabric, the starting thermal decomposition temperature of modified PP nonwoven shifts toward high temperature, indicating that its thermal stability is enhanced. 14,15 In addition, the weight retention rate of PP nonwoven remains at 0% when the temperature exceeds 440°C, showing that PP nonwoven has been completely pyrolyzed. In comparison, the weight retention rate of modified PP nonwoven fabric remains at 40% when the temperature exceeds 460°C, demonstrating that there was still residue after pyrolysis; the residue was CaCO 3 component with the content of 40% (m/m).…”

Nano-CaCO3-modified polypropylene (PP) nonwoven fabric composite is widely used as the filter material which could overcome the poor lightfastness and low weight of the pure one, while its aging performances would be influenced. In this article, the aging behavior of the nano-CaCO3-modified PP nonwoven fabric composite was investigated. At first, the difference between untreated and CaCO3-modified PP nonwoven fabric was analyzed by scanning electron microscopy, thermogravimetric/differential thermal analysis, and X-ray diffraction. Then the aging behaviors of these two PP nonwoven fabrics were studied in detail. The results showed that the PP nonwoven fabric exhibited good acid corrosion resistance. On the contrary, acid corrosion resistance of the modified PP nonwoven fabric was poor; although its weight and strength didn’t change under weak acid condition, its weight and strength loss both increased obviously under medium and strong acid condition with the prolongation of corrosion time. Due to the ultraviolet (UV) energy dissipation of nano-CaCO3 particles, the UV aging resistance of the modified PP nonwoven fabric was improved, and the compound UV aging under weak acid condition was also superior to that of the untreated PP fabric. This article will provide experimental and theoretical base for the structural regulation of CaCO3-modified PP fibers.
