The factors which influenced the content of carbon nanotubes in deposits, such as the types of agitation, surfactants and carbon nanotubes concentration in the plating bath, were examined.
Carbon nanotubes (CNTs) have superstrong mechanical properties [10,11] and good lubricity as graphite [12].
These properties of carbon nanotubes make them to be possible in developing composite coatings with excellent comprehensive properties.
Obviously, this surface structure of the coating might be excellent tribo- logical properties and high wear resistance because of the superstrong mechanical properties [10,11] and self-lubri- cation of CNTs [12] in comparison with the Ni-P coatings without carbon nanotubes.
The important factors affected the content of carbon nanotubes in the deposits were the surface properties of the tubules and the movement of carbon nanotrubes in the bath nearby the depositing surface.

Although the carrier mobility decreases with temperature, the effect of these properties increasing will explain the overall increase in photocurrent.
Fill factor is a measure of how affected a device is by its non-idealities, such as series resistance and ideality factor.
This decrease in fill factor indicates that the device is degrading structurally and becoming more affected by non-idealities.
Increase in these properties has a detrimental effect on fill factor as they reduce the devices ability to output the electrical power it generated.
The power produced exhibits a positive temperature coefficient and a stable fill factor, indicating that the device is not overly affected by variations in series resistance and ideality factor.

Effect of Concentrated Alkali Treatment on the Properties of Naturally Colored Brown Cotton Li Chen1,a,Yusen Liu 1,Weiguo Sun1,Xiaoyan Zhou1 1School of Textile & Materials，Xi’an Polytechnic University，Xi’an，People’s Republic of China afychenli@yahoo.com.cn Keywords：naturally colored cotton,crystallinity,morphology,mechanical properties,color.
The naturally colored cotton fiber was treated by sodium hydroxide solution with different concentrations and temperatures.The surface morphology,crystalline structure, mechanical properties and color feature value of fiber after treatment were tested by SEM,XRD,electronic single fiber strength tester and Computer Color Matching meter.The results show that the longitudinal convolutions of the naturally colored cotton fiber treated by concentrated sodium hydroxide decreased or disappeared,and the fiber became nearly cylindrical or cylindrical.The crystallinity of fiber after treatment decreased,part of the celluloseⅠ changed into celluloseⅡ．The breaking strength and breaking elongation of fiber after treatment increased.The total color differences（ΔE） and value a*of fiber after treatment increased，to the contrary，value L* and value b* decreased，which leaded to that the color of fiber treated by alkali became darker．In addition,the treatment temperature had larger influence on the properties
colored cotton and ordinary white cotton are very similar in chemical composition,structure and other properties.But there are still many differences between them.So it is necessary to explore the effect of concentrated sodium hydroxide on the properties of naturally colored cotton.The changes of the performance of naturally colored cotton treated by concentrated sodium hydroxide were analyzed and obtained through a large number of experiments.These results can provide a theoretical reference for the formulation of related technology in naturally colored cotton treatment process with sodium hydroxide.
Mechanical Properties of Fiber Fiber specimens were conditioned for 24 hours at 20°C and 65% relative humidity prior to testing.The samples were tested according to GB/T14337-93 standard reference.The fiber breaking strength and breaking elongation were measured by YG001 electronic single fiber strength tester,operating at a 10mm Clamping distance,a 0.1cN pretension,and a 10mm/min rate of decline.
Mechanical Properties of Fiber （a）Breaking strength of naturally colored cotton fiber（b）Breaking elongation of naturally colored cotton fiber Fig.3 Mechanical Properties of naturally colored cotton fiber before and after treated by concentrated Sodium hydroxide Fig.3 shows that,the breaking strength and elongation of fiber after treatment increased,and the breaking strength and elongation of fiber treated at 20℃ were greater than that of fiber treated at 60℃.The results of fiber crystallinity show that,the crystallinity of fiber treated by concentrated Sodium hydroxide decreased.The crystallinity affects the strength of fiber.Usually,the lower the crystallinity value is,the lower the strength value of fiber is.But the strength of fiber also are impacted by the orientation degree of fiber and other factors.Concentrated Sodium hydroxide solution could cause irreversibly anisotropic swelling of naturally colored cotton fiber,the diameter of fiber increased and the longitudinal length
