In Fig. 5b and d, the polyester fibers were melted together and the fiber structure is hard to observe.
The fiber structures can be still seen in the Fig. 5c, which indicates that the calcium ion crosslinked coating has better ability to resist the shrinkage during combustion.

The samples prepared by conventional thermal heating method mainly consist of irregular and small particles, whereas the samples prepared by micro- wave heating method have elongated rope-like structure and their length extends longer than 10 µm.
Recently, microwave synthesis has been applied successfully for the synthesis of MCM-41 which is known as a promising material for applications like guest-host chemistry and organic/inorganic composite materials [2].
The technique to tailor the structure and morphology of ordered mesostructured inorganic materials is a vital factor in their use.
The XRD patterns of MCM-41 samples clearly show that a typical MCM-41 material with a relatively well ordered structure is synthesized by both the heating methods.
However, it is demonstrated in this work that the microwave heating induced the formation of fibrous MCM-41 structure only after 3 h of crystallization time.
