Atmospheric-pressure Air Plasma Treatment of Polyester Fabrics for Inkjet Printing with Pigment Inks

Without any preprocessing,polyester fabric has lower ability to hold on water and inks due to the smooth morphology of polyester fibers. Therefore, patterns directly printed with pigment inks have poor color yields and bleed easily. Pretreatments of polyester fabric were carried out with atmospheric air plasma under different experimental conditions. After plasma treatment the samples were printed with magenta pigment ink. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) analyse...

Patterning the neuronal cells via inkjet printing of self-assembled peptides on silk scaffolds

The patterning of neuronal cells and guiding neurite growth are important for neuron tissue engineering and cell-based biosensors. In this paper, inkjet printing has been employed to pattern self-assembled I₃QGK peptide nanofibers on silk substrates for guiding the growth of neuron-like PC12 cells. Atomic force microscopy (AFM) confirmed the dynamic self-assembly of I₃QGK into nanofiber structures. The printed self-assembled peptide strongly adheres to regenerated silk fibroin (RSF) substrates through charge-charge interactions. It was observed that in the absence of I₃QGK, PC12 cells exhibited poor attachment to RSF films, while for RSF surfaces coated or printed with peptide nanofibers, cellular attachment was significantly improved in terms of both cell density and morphology. AFM results revealed that peptide nanofibers can promote the generation of axons and terminal buttons of PC12 cells, indicating that I₃QGK nanofibers not only promote cellular attachment but also facilitate differentiation into neuronal phenotypes. Inkjet printing allows complex patterning of peptide nanofibers onto RSF substrates, which enabled us to engineer cell alignment and provide an opportunity to direct axonal development in vitro. The live/dead assay showed that printed I₃QGK patterns exhibit no cytotoxicity to PC12 cells demonstrating potential for future nerve tissue engineering applications.

斜入射时Salisbury屏电磁参数匹配规律研究

利用电磁波传输理论,研究并推导出了电磁波斜入射时Salisbury屏后向反射率公式,使用三维网格法讨论了各个电磁参数、隔离层厚度、入射波频率等同后向反射率之间的关系.研究结果表明:在2～18GHz范围内,角度后向反射率有很大;在f=16GHz时,μ_(r1)和μ_(r2)取值的增加使得材料的磁损耗和储能能力加强,导致材料有很好的吸收效果;然而ε_(r1)和ε_(r2)取值增加时,由于表面反射效应增强,使得吸波效果下降;在2～18GHz频段内后向反射率均可达到4.5dB以上,能够满足军事和民用的要求.     

Forming mechanism of ink layer on the printing plate in inking process and influencing factors of its thickness

Ink layer thickness on the printing plate greatly influences uniformity of ink transferred to the substrates , which is an important indicator of printing quality , so the study of ink layer and its thick-ness is important for improving the quality of printing products .Ansys CFX is used here to build a model of ink fluid adhering to lower vibrator roller , form inking roller , and printing plate for analy-zing ink transferring in inking process .Ink layer thickness on each position of the model is acquired to analyze the forming mechanism of ink layer on printing plate , as well as the influence of oscilla-tion speed of lower vibrator roller and dot area percentage of plate on ink layer thickness of printing plate.It can be concluded that , in the case of fixed ink supplying amount , ink layer thickness in-creases along with the increasing of oscillation speed , and decreases when the dot area percentage is getting larger and the minimum is got when the dot area percentage is 100%.At last , experiment of plate inking on print ability tester verifies the correctness of the simulation analysis .
