The ability of surfactants to self-assembly in well defined structures has the advantage of synthesis and design of inorganic/organic materials with nanometric size [2].
The nanoporous materials are formed when inorganic oxides (e.g. silica) polymerize in the presence of surfactants with "template" role, which serve as structure-directing agents for the oxide framework, by using the sol-gel method [3].
Sol-gel matrices can be fabricated as self-supporting structures applied to a variety of inorganic or organic compounds.
All of three quaternary ammonium salts are amphiphilic and miscible with water and ethanol, therefore they act by self-assembly as structure - directing agents in an acidic water - ethanol - TEOS solution.

Through sol-gel method, the composite can form a spatial network structure on the fabric surface and combine with the cotton fibers through hydrogen bonding and van der Waals.

According to the International Union of pure and Applied Chemistry (IUPAC) classification criteria, porous structure of activated carbon can be divided into micro-pore (r<2nm), meso-pore (2nm50nm) based on pore size.
Meso-porous activated carbon, as the electrode materials of super capacitor, can improve the capacitance and cycling property for its high specific surface, better conductivity, chemical stability and suitable pore structure [4,5].

As expected, by using this solvent system in the experiment, we obtained PLA/PEO bicomponent fibers with numerous pore-like structures appeared on one side of the fiber surface, i.e.
Bicomponent fibers structure.
To confirm the continuity of PLA phase and fibers structure, PLA-PEO bicomponent fibers were dissolved in water for adequate period.
This simple concept could be useful for several applications such as catalytic and sensor application by employing the smooth continuous phase as a mechanical support for a more fragile porous structure, which provides large surface area for the applications.

The B-N and C-C pair are separated in different layers in U1 structure while mixed in the same layer in U2 structure.
In the other structures, the B-C, N-C, N-N, B-N bonds don’t appear in pairs, thus bonding balance cannot be kept and the structures are distorted.
