A novel Fullerene-ltaconic acid copolymer is synthesized via radical polymerization. It issoluble in polar solvents such as water, methanol, acetone and tetrahydrofuran etc.. The molecularstructure is identified and characterized by FTIR, UV-Vis and GPC. TEM analyses shows that itpresents an ideal spherical shape in water with an average diameter of about 48nm. Four-balltests show that the addition of a certain concentration of the Fullerene copolymer to the base stockcan effectively raise the load-carrying capacity (P_B Value) and the antiwear ability. JSM-35C modelscanning electron microscope (SEM) is used to examine the morphologies of the worn surfaces,which show that the additive results in a smaller wear scar diameter and a more shallow weargrooving.

火催生了人类文明,从茹毛饮血到美味佳肴,从简单石器打磨到精美的瓷器烧制,从火药发明使用到航天技术,无不经历着火的洗礼.火在给人类带来福祉的同时,也带来了灾难,在一次次生命财产惨痛损失的感召下,促使人类对燃烧和灭火的重视和研究.为此,初中化学教材引入了燃烧和灭火.为更好地理解和把握这部分知识,现将燃烧和灭火作一梳理.  一、燃烧条件和灭火原理  燃烧条件:(1)物质具有可燃性.(2)可燃物与氧气接触
