Customizing Properties of β-Chitin in Squid Pen (Gladius) by Chemical Treatments

The squid pen (gladius) from the Loligo vulgaris was used for preparation of β-chitin materials characterized by different chemical, micro- and nano-structural properties that preserved, almost completely the macrostructural and the mechanical ones.

The β-chitin materials obtained by alkaline treatment showed porosity, wettability and swelling that are a function of the duration of the treatment.

Microscopic, spectroscopic and synchrotron X-ray diffraction techniques showed that the chemical environment of the Nacetyl groups of the β-chitin chains changes after the thermal alkaline treatment.

As a consequence, the crystalline packing of the β-chitin is modified, due to the intercalation of water molecules between β-chitin sheets. Potential applications of these β-chitin materials range from the nanotechnology to the regenerative medicine.

The use of gladii, which are waste products of the fishing industry, has also important environmental implications.
