And Behavior

The prepared n-Cu particles with the particle size about 20 nm by KBH4 reduction method in aqueous solution was surface modified using silane coupling agent. The surface modification mechanics was researched. The tribological performances of n-Cu particles were tested by friction wear test machine. The results show that the modified n-Cu paritcles by silane coupling agent have high purity, good dispersion performances and wonderful surface activity. In friction process, the modified n-Cu particles can form a layer of organic-inorganic compound film with synergistic effect on worn surface, which improves the tribological performances of friction material.

Attapulgite was organic surface modified with silane coupling agent (KH570) and acetone, with ferric chloride (FeCl3∙6H2O) as the oxidant, sulfamic acid(SA) as dopant, prepared polypyrrole/attapulgite with organic surface modification conducting nano-composite materials (PPy/ATTP-KH) by chemical oxidation polymerization, and using IR, XRD and SEM characterization methods to characterize Internal structure of composite materials obtained. The results show that in the condition of n(Py):n(FeCl3∙6H2O):n(SA) =1:1:0.5, and with the increase of contents, composite conductivity increased and then decreased, when the contents of attapulgite is to 50%, the conductivity reaches maximum 30.0 S•cm-1. We can see from the IR spectrum, silane coupling agent and hydroxyl of attapulgite surfaces have a chemical bonding, and plays a good modification to the surfaces of attapulgite, Thereby enhancing the conductivity of the composite materials.

A uniform, monodispersed superfine cuprous oxide (Cu2O) sphere with a mean diameter of 850 nm has been synthesized by solution reduction. The study reported the synthesis and thermal properties of Cu2O/PP composites for the first time. The surface modification of the superfine Cu2O sphere was carried out by using a silane coupling agent KH-570. Fourier-transform infrared (FTIR) spectroscopy and the thermogravimetric analysis (TGA) curve revealed that the Cu2O had been successfully modified by silane coupling agent KH570. The scanning electron microscope (SEM) shows that the modified Cu2O can be uniformly dispersed in the polypropylene (PP) matrix, because through surface modification, there are some active functional groups on its surface, such as the ester group, which improves its compatibility with the PP matrix. The thermal stability of Cu2O/PP composites was improved by adding a small amount of Cu2O (1 wt % of PP). Therefore, based on the potential bacteriostasis of cuprous oxide, the low cost of PP and the results of this study, it is predicted that Cu2O/PP composites can be used in infant preparation (such as milk bottles) with low cost and good thermal stability in the near future.
