Introduction Chitosan is a non-toxic and chemically reactive, and biocompatible natural functional polymer, and has long been used as a biopolymer and natural material in many fields[1,2].
Organosilicon has advantages such as excellent flexibility, elasticity and the easiness in film forming due to dual characteristic of both organic and inorganic materials and unique structure[7].
Experimental Materials Boiled and bleached cotton fabric(150g/m2); Degrading commercial chitosan (the viscosity average molecular weight is 50,000, and degree of deacetylation is 85%); HA-920 epoxy-silicone micro-emulsion; Acetic acid was of analytical grade.

Experimental Starting materials.
The materials used in the preparation of blend electrolytes of respective blend polymer electrolyte System-I and System-II are polyvinyl alcohol (PVA) (mol. wt. = 115,000-Lobachemie), polyethylene oxide (PEO) (mol. wt. = 1000,000-Alfa Aesar), polyethylene glycol 4000 (PEG) (mol. wt. = 3,500-4,000-Lobachemie), ethylene carbonate (EC) (mol. wt
However, for a solid polymer electrolyte material, it is highly essential for the charge transport to occur predominantly due to ionic species than due to electronic species i.e. ti value should be closer to unity.

Considering traditional SnO2-based gas sensor working with higher operating temperature and lower gas response, preparation of 1D SnO2 materials and investigating their gas sensing properties to characteristic fault gases dissolved in transformer oil are in great demand.
Gao: Journal of Nanomaterials, Vol. 2012, (2012) Article ID 612420, 9 pages. doi:10.1155/2012/612420. ].
Such a higher quasi-linear dependence indicates that the as-prepared fiber-like SnO2 based gas sensor can be used as promising materials for online monitoring H2 dissolved in transformer oil.
As we know SnO2 is a typical n-type semiconducting material, and its gas sensing property was dominated by the change of surface electrical resistance.When placed in air ambient SnO2 nanofibers adsorb the oxygen molecule on the surface and a depletion region is formed on SnO2 surface, which decreases the number of charge carriers.
Dai: Science, 287 (2000) p.622. ], which makes them highly sensitive and efficient transducers of surface gas sensing reactions into electrical signals.

Each state involves five feature types of the material, function, structure, process, and management.
Although each state describes the different point of manufacturing chain, overall features such as material and function information are the same in manufacturing states and design state.
