Abstract

In situ Pd-catalyzed cyclopentene polymerization in the presence of multi-walled carbon nanotubes (MWCNTs) is demonstrated to effectively render, on a large scale, polycyclopentene-crystaldecorated MWCNTs. Controlling the catalyst loading and/or time in the polymerization offers a convenient tuning of the polymer content and the morphology of the decorated MWCNTs. Appealingly, films made of the decorated carbon nanotubes through simple vacuum filtration show the characteristic lotus-leaflike superhydrophobicity with high water contact angle (>150 degrees), low contact angle hysteresis (<10 degrees), and low water adhesion, while being electrically conductive. This is the first demonstration of the direct fabrication of lotus-leaflike superhydrophobic films with solution-grown polymercrystal- decorated carbon nanotubes.

Organic Non-Wettable Superhydrophobic Fullerite Films

Rinku Saran, David Fox, Lei Zhai, Debashis Chanda

Summary: This study develops non-wettable superhydrophobic films based on colloidal gels of fullerite C-60 and C-70 nanocrystals, with self-affine fractal surfaces, multiscale roughness, and water droplets beading like pearls with contact angles exceeding 150 degrees. These films exhibit extremely high water repellency and can stay dry up to 3 hours in water, even at a depth of two feet, showing the plastron effect. The films have the ability to instantly generate singlet oxygen, enabling their use in water purification and medical devices.

Studying the effects of carbon nanotube contents on stretch-induced crystallization behavior of polyethylene/carbon nanotube nanocomposites using molecular dynamics simulations

Jun Yang, Zongfa Liu, Zhiping Zhou, Yongqiang Ming, Sumin Li, Tongfan Hao, Yijing Nie

Summary: This study used molecular dynamics simulations to investigate the influence of carbon nanotube (CNT) content on the crystallization behavior of CNT-filled polyethylene systems under stretching. The results showed that higher CNT content led to greater orientation and more trans-conformation during stretching, resulting in the formation of more precursors. However, when the CNT content exceeded a certain threshold, the formation of a filler network restricted chain movements and decreased the overall crystallization rate.

Superhydrophobic Carbon Nanotube-Metal Rubber Composites for Emulsion Separation

Zhiying Ren, Mingzhi Fan, Zhen Zhang, Youxi Lin, Zhiguang Guo

Summary: In this study, a superhydrophobic material with a three-dimensional network frame protection was successfully constructed using metal rubber (MR) as the substrate and filling multiwalled carbon nanotubes (MWCNTs) into the pores of MR through poly(dimethylsiloxane) (PDMS) anchoring. The separation mechanism of superhydrophobic MR for emulsions was investigated, and the separation efficiency was predicted by analyzing the depth retention effect. The results demonstrated excellent purification capability and mechanical stability of the prepared superhydrophobic MR for water-in-lubricating oil emulsions.

Phenomenological model of thermal transport in carbon nanotube and hetero-nanotube films

Pengyingkai Wang, Ya Feng, Rong Xiang, Taiki Inoue, Anton Anisimov, Esko Kauppinen, Shohei Chiashi, Shigeo Maruyama

Summary: The thermal properties of individual single-walled carbon nanotubes have been extensively studied, but the thermal transport in assembled structures depends on bundling and inner structural details. Experimental measurements of SWCNT bundle thermal conductivities were used to understand bundling effects, leading to a phenomenological model for thermal transport in SWCNT films. This model was extended to explain thermal transport in one-dimensional van der Waals heterostructures, showing that the transparency of the film affects the overall performance.

Impact-resistant carbon nanotube woven films: a molecular dynamics study

Fan Wu, Yushun Zhao, Yifan Zhao, Yue Zhao, Chao Sui, Xiaodong He, Chao Wang, Huifeng Tan

Summary: Fiber-based fabrics have great potential in impact protection, and a novel nanostructure using SWCNTs to weave 2D films has been proposed. Through MD simulation, it was found that SWFs exhibit significant anisotropy in mechanical properties, with the best performance when loaded along the CNT axis. The SWF demonstrated high strength and energy absorption, attributed to the intrinsic strength and flexibility of CNTs.
