Ga-In liquid metal nanoparticles prepared by physical vapor deposition

Progress in Natural Science Materials International (2018)

Yu Fan Jiale Xu Huiqin Li Zizhao Wang Limin Sun

Controlled synthesis and appropriate characterization of nanoscale particles of gallium-based liquid metals are critical to fulfilling their broad range of applications in the field of flexible, stretchable, and printable micro-/nanoelectronics. Herein, we report a new way to synthesize surfactant-free gallium-indium nanoparticles with controlled particle size on a variety of substrates through a facile physical vapor deposition method. It was found that with prolonged deposition time the liquid metal nanoparticles gradually grew from near-monodispersed small particles with a diameter of ~25 nm to bimodal distributed particles. A nucleation, growth, ripening and merging process was proposed to explain the observed evolution of particle size. Atomic force microscopy measurement indicates that the fabricated liquid metal nanoparticles demonstrate elastic deformation with a certain range of loads and the scanned particle size is dependent on the applied loads. We further investigated the gradual breaking process of the core-shell structured liquid metal nanoparticles, which was evidenced by multiple kinks on the force-separation curve. This work presents a new bottom-up approach to prepare nanoscale liquid metal particles and demonstrates that atomic force microscopy is a suitable technique to characterize the synthesized liquid metal nanoparticles.

Electrical Tree Characteristics of Isotactic/Syndiotactic Polypropylene Blend Insulation under Repetitive Impulse Voltage

Wei Yang Yu Fan Zhaoliang Xing Shuofan Zhou Mingsheng Fan

Polypropylene (PP) is an emerging direction of thermoplastic and crosslink-free cable insulation material due to its excellent electrical and heat resistance properties. This article concentrates on the electrical tree characteristics of Isotactic PP (iPP)/Syndiotactic PP (sPP) blend insulation under repetitive impulse voltage. Five samples of iPP/sPP blend with sPP contents of 0, 5, 15, 30 and 45 wt% were prepared in aim to analyze the electrical tree initiation and growth characteristics. Electrical tree tests under repetitive impulse voltage were performed by the needle-plate electrode system under 30, 50, 70 and 90°C. When sPP content is between 0 and 15 wt%, the increase of sPP content inhibits the growth of electrical tree. With the continuing increase of sPP content, the initial probability and growth rate of electrical tree rise due to the decrease of deep trap density. The PP blend with 15 wt% sPP shows an excellent resistance to electrical tree, which is attributed to the highest deep trap density. Deep traps are easier to capture injected charges and form homogenous electrical field, which results in the inhibition of charge injection under repetitive impulse voltage. Moreover, the increased deep trap density is conducive to reduce the mean free path of charges and confine impact ionization, resulting in the lower growth speed of electrical tree.

Preparation of safflower oil microcapsules with gelatin and a novel exopolysaccharide as wall matrix

Journal of Food Process Engineering (2017)

Shuhong Ye Yu Fan Yuna Cui Dun Chen Lingxi Kong

Abstract Gelatin and exopolysaccharide (EPS) as wall matrix were investigated for safflower oil microcapsules using complex coacervation. The EPS from Pseudomonas PT‐8 was negatively charged, which can react with positive charge of gelatin electrostatic to yield polymer rich phases. Single factor and orthogonal tests were carried out to determine optimal preparation conditions, mixing gelatin (30 g/L) and EPS (30 g/L) with a ratio of 5:4 at pH3.6 firstly, then coating safflower oil with 50 g/L gelatin‐EPS, 60 g/L Tween 80, and Span 80 (1:1) as emulsifier and 3‰ transglutaminase (TG) as cross‐linking agent, encapsulation efficiency of microcapsules reached 81.27% by cross‐linking for 120 min at 20,000 rpm. Free flowing spherical microcapsules were made up of small round particles whose diameters were between 1 and 20 µm. When microcapsule powder dissolved in water, it can be dyed well by safranin due to its good dispersivity. Evaluation of endotoxin suggested that gelatin–EPS was not contaminated by endotoxin. Practical applications Gelatin and a novel microbial polysaccharide as shell matrix are used in safflower oil microcapsules. It can be easily digested by the body and effectively decrease undesirable taste and odor. It also can keep the ability of reducing blood viscosity, improving blood circulation and enhancing memory, due to the special shell.
