The effect of different ratio in carbon aerogel on pore structure in ambient dry Fang Wang1,a, Lanfang Yao1*,b, Jun Shen 2,c,Dayong Guan 2*,d, Zhou Fang2,e 1 College of science, University of Shanghai for Science and Technology， Shanghai 200093，China 2 Shanghai key laboratory of special artifical microstructure materials and technology, pohl institute of solid state physics, tongji university, shanghai 200092, China.
Introduction Carbon materials produced through the pyrolysis also known as carbonization process of organic aerogels with porosities in nanometer range are required for various emerging technologies ranging from absorbents and catalysts to battery electrodes and supercapacitor.
The first RF organic aerogel was synthesized by Pekala through the aqueous polycondensation of resorcinol with formaldehyde using sodium carbonate as the base catalyst, where its associated chemistry is similar to the sol-gel chemistry in inorganic materials.
The results had shown that the mass ratio had an obvious effect on the material’s microstructure.

Among most important factors are the properties of sliding materials and lubricant, load/velocity input and contact geometry, but also dynamic characteristics of the machine (tester) which influenced the friction process.
Tests were carried out on various metallic materials with the use of an inertial tribometer in a flat – on – cylinder contact configuration.
