| Summary: | This paper contains a selection of parameters in sol gel synthesis to produce thin layer tin octoate, Sn(Oct)2. The main purpose is to discuss the effect of binder on morphology and chemical structure in order to produce high quality coating. The sol-gel method gives better control of the texture, composition homogeneity and structural properties of the final product. However, the disadvantages of this process is the formation of cracks during drying of gels. Binder is one of the compounds help to prevent cracking. In this research, Sn(Oct)2 was synthesized through sol-gel method with the addition of binders which are polyvinyl alcohol (PVA) and polyethylene glycol (PEG) to enhance mechanical strength of sol gel coating on glass substrate. Different concentration of binder were varied to produce Sn(Oct)2 thin film. The paper first describes the effect of binder on spectral characteristic from chemical bonding. Then, the effect of binders toward membrane features also studied. The characteristic of thin layer with binders were also discussed. FTIR characterization used to determine the chemical compound and crystalline structure was confirmed by XRD analysis. It has been shown that, added binder into the solution is an effective method to improve the strength of thin layer. © 2018, Malaysian Society of Analytical Sciences. All rights reserved.
