Fabrication of in-situ Formed Namo-Composite Using Polymer Precursor : I. Adsorption Behavior of Polymer Followed $SiO_2$ Surface formation onto Silicon Nitride Surface
Adsorption behavior and amount of phenolic resin followed silica (SiO2) formation onto silicon nitride(Si3N4) surface were investigated using electrokinetic sonic amplitude (ESA) technique and with UV spectrometer, to fabricate Si3N4/SiC nano-composite based on reaction between SiO2 formed and phenolic resin absorbed onto Si3N4 particle. The amount of SiO2 formed and carbon from phenolic resin absorbed onto Si3N4 surface were calculated quantitatively to adjust the reaction between SiO2 and phenolic resin, resulting in no residual SiO2 and carbon. As a result, pre-heated tempeature for optimized reaction was below 25$0^{circ}C$, in which there was no residual SiO2 and carbon.
Key words: Adsorption behavior, Silica, $Si_3N_4/SiC$ nano-composite, Electrokinetic behavior, Pre-heated temperature
