“…The chain-like aggregation structure of CB particles forms a stronger conductive network than that of other carbon-based materials and, at the same time, the higher filler content leads to little combining with the polymer matrix. 74 CF has become an attractive shielding material due to its high specific strength and high conductivity. However, the absorption capability of CF is poor, which results in poor further attenuation of electromagnetic waves when used as a single medium.…”

Carbon-based electromagnetic shielding materials are reviewed in terms of their performance, type, and preparation. They include film, composite, foam, and fabric with particular attention on their frequency selectivity ascribed to the periodic structure. The SE/t, referring to shielding effectiveness per unit thickness (dB/mm), and SSE, referring to shielding effectiveness per unit density (dB·cm3/g), are summarized. The main conclusions of this work are as follows: (1) large area film shows higher SE/t, in which carbon nanotube (CNT) film is endowed with the most attractive value (19,500 dB/mm); materials containing CNTs achieve higher shielding efficiency, ascribe to a high specific surface area, have a greater length–diameter ratio, and a one-dimensional continuous-oriented structure; (2) notably, frequency selectivity based on varied period structures has been widely studied; the method includes multilayer structure/printing/cutting/backfilling and, especially, woven fabric; (3) favorable shielding effectiveness is attributed to the shielding material's intrinsic electrical conductivity and structural integrity. Based on these developments, this paper aims to provide some valuable data, highlight the important research direction, and advance the development of carbon-based electromagnetic shielding materials.

“…It has been over one decade that carbon black (CB) nanoparticle became one of the interesting materials to modify polymer nanofiber due to small particle size (high surface area), aggregation behavior, low cost and conductive property [20][21] Those properties make CB has usability as an adsorbent material [22]. Islam et al [23] reported that CB is the most effective adsorbent material than extruded activated carbon and granular activated carbon.…”

Carbon black/PVDF copolymer (CB/PVDF copolymer) nanofiber composite has been synthesized by electrospinning process. Nanostructure and surface property of CB/PVDF copolymer were studied by using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD) and water contact angle (WCA). Nanofiber composite has smooth surface morphology without bead on nanofiber string. Increase of CB content in nanofiber composite decreased diameter of nanofiber size. Range of average nanofiber diameter was from 405.2 and 421.3 nm where it depended on CB content in nanofiber composite. FTIR and XRD analysis showed that structure of PVDF copolymer in nanofiber composite had a dominant β phase crystal structure. The β phase was showed and confirmed by vibration band peak at 838.55 cm-1 of IR spectrum and 2θ = 20.44° of XRD. Presence of CB in nanofiber composite also influenced WCA and water spreading on nanofiber composite. WCA of pristine PVDF copolymer, CB/PVDF copolymer nanofiber with 1% CB, and CB/PVDF copolymer with 5% CB were 113.8, 105.2, 117.3°. From this result showed that nanostructure and surface characteristic can be adjusted and controlled by presence of CB in nanofiber composite. This result has potential application for air filtration to solve air pollution issued.

His research interest is in the field of hazardous waste and environmental monitoring such as air and water pollution. The 11th International Conference on the Science of Hard Materials (ICSHM11) attempts to bring together scientists, technologists and manufacturers of Hard Materials. This broad but unique set of materials includes technically successful and continuously evolving subgroups such as cemented carbides, cermets, advanced ceramics, composites and super-hard materials. Through the years, synergy between science and technology has catalyzed achievement of superior quality and enhanced performance of components, tools and devices of hard materials by means of innovative microstructural design at different length-scales: bulk/film, monolithic/composite, functionally graded, surface modified, and micro/nano-structures. As a consequence, the range of applications for hard materials has been growing not only within consolidated sectors such as metalworking, mining, oil-and gas-drilling, construction, process and machine building industries, but also into high-tech and emerging technologies in the electronics, aeronautics and dental sectors, among others. As it has been the tradition in the previous ten conferences, the aim of ICSHM11 will be to provide an interdisciplinary forum for presentation, discussion and exchange of modeling,...
