In this research provides commercially available methods for the mass production of graphene coated textiles using the continious dyeing process,and exhaust dyeing method;for electomagnetic interference(EMI)shielding.The research work is based on the design and development of highly conductive textile to use as regular clothing to protect EM radiation for human body.The woven and knitted fabric structures of cotton fabric were fabricated with reduced graphene oxide(rGO)and Poly-ethoxide trimethyl sulphonate(PEDOT:PSS)Nano-hybrids using commercially available continuous dyeing method and exhaust dyeing method.The cotton fabric had higher wet pick up 60-80 percent with deficient solution consumption 2.5-5.0g/50.0 mL at a higher production rate of 1.0-5.0 m/min under atmospheric pressure of 100 cN/cm2 for the woven cotton fabric.The continuous dyeing and reduction were achieved simultaneously,over a temperature of 90-100℃ and chemically reduced into GO to rGO and prepare the highly conductive and flexible textile for EMI shielding.Similarly,in the second method,the exhaust dyeing method was used for knitted cotton fabrics to fabricate rGO-PEDOT PSS hybrid.The GO dye solution was loaded with reducing agent and dyeing process was carried out at 100℃ on the continuous dyeing machine.The GO was directly dyed and converted into rGO and fixed on cotton fabric by a simple exhaustion dyeing process.The reduction of GO-dyed fabric was efficiently completed by an increasing the concentration of rGO and C6H8O6(L-ascorbic acid)as a green,reducing agent with weight ration 4:1 respectively.The results showed improved electrical conductivity as compared to natural rGO coated fabrics when the fabric was coated with PEDOT:PSS as a second layer using layer by layer approach,and post-treated with(DMSO)and(EG)after reduction for 1h above 90℃.Moreover,the results showed that when increasing the volume%of rGO(2.5,5.0,10.0,20.0 and 40.0)percent significantly reduced the sheet resistance and improved the tensile strength,washing,rubbing,and color fastness properties of the rGO-dyed cotton fabric for EMI shielding performance in particularly enhanced up to-49 dB on 30-1530 MHz frequency range on X band.

最近几年,以MAPbI_3为代表的有机-无机杂化金属卤化物钙钛矿半导体材料,由于具有较长扩散长度、较高载流子密度与较大吸收系数以及低廉的制作成本与快速增长的光电转换效率,成为光伏领域最受关注的吸光层材料之一。本文结合金刚石对顶砧加压技术和微纳光学表征技术,系统的研究了微米级MAPbI_3单晶片的光致发光(PL)光谱、可见近红外吸收光谱与光学显微图像,揭示了其晶体结构与光学性质在压力条件下的演化过程

森林资源同时拥有着经济效益与生态效益,而生态公益林是主要发挥森林生态效益的森林、林木、林地。为了最大程度的发挥生态公益林的生态效益,国家严格限制甚至禁止了生态公益林的采伐活动,生态公益林经济效益的实现因此受到极大程度的影响,无法实现生态公益林的经济效益会挫伤生态公益林经营者建设生态公益林的积极性。因此,为了调动生态公益林经营者建设生态公益林的积极性,就必须对其损失的经济效益进行弥补,而生态公益林补

平淡1是中国古典美学中重要的审美范畴,它渊源于道家的思想。后代的大多数诗人和画家视平淡为一种审美信仰,这不仅使他们的生活愿景和艺术情怀产生潜移默化的改变,同时为继承和发扬平淡美学思想做出了不可估量的贡献。在这个变化复杂的社会,平淡凸显珍贵,很值得我们当代青年人去探究和领会。《影趣》系列试图在绘画创作中诠释平淡美,原因是平淡美对笔者形成自己的绘画风格和对待生活的态度有重要启示。本文以介绍《影趣》系列
