“…were well matched with the previously reported data [18,20]. The FTIR spectrum of chitosan showed all the characteristic stretching vibrations for -OH at 3464 cm [4,20,33,34]. Gellan showed the characteristic stretching vibrations for -OH at 3419 cm -1 , C-H at 2121 cm -1 , asymmetric carboxylate at 1612 cm -1 , symmetric carboxylate at 1400 cm -1 and pyranoside ring at 1047 cm -1 [23,35,36].…”

Scientific research has been invigorated by a new class of biodegradable materials as alternatives to polymers derived from fossils. Such biomaterials can also offer economic advantages because they are derived from renewable resources. Several biopolymers (gelatin, chitin, chitosan, starch, pectin, cellulose and its modified versions, etc.) have been exploited to produce films and formulations. Their use is limited because of fast degradation, predominant hydrophilic character, and, in some cases, unsatisfactory mechanical properties. However, the properties of these polymers can be improved by using inorganic fillers such as additives. Halloysite nanotube is a promising green filler for this purpose.

“…Recently, the results of researches on chitosan/clay nanocomposites to further improve their performance in various properties have been reported [8][9][10][11][12][13][14][15]. Darder et al [8] employed cationic biopolymer chitosan into Na + -montmorillonite (Na + -MMT), providing a -NH 3 + functional group for the anion exchange site as an anion sensor.…”

Chitosan/clay (nano)composites were prepared by using a special quaternary ammonium intercalating agent coupled with a silanol group to facilitate the organic clay formation. Exfoliated clay in the chitosan matrix was attained at the higher intercalant dosages through X-ray diffraction (XRD) and transmission electron microscope (TEM) analyses. Optical transmittance for the (nano)composites increased slightly with increasing the amount of intercalants in the clays. In light of the hydrophobic component on the intercalant and the effective clay content, the interfacial interaction between chitosan and modified clay may not be strong enough to render higher mechanical properties, even though the partially exfoliated clays were achieved to provide high interfacial area for the dispersed phase and the matrix. An optimum Young's modulus was thus found for (nano)composites using modified clay at a medium dosage of intercalant, which resulted from the balance of the dispersion status and interfacial interaction. This outcome indicated high dispersion of modified clay may not guarantee high mechanical properties of (nano)composites. The antimicrobial property of chitosan against Escherichia coli (E. coli) increased further with the addition of modified clays, in which the intercalant exhibiting the antimicrobial function. The modified clay at an optimum dosage of modifier to balance the mechanical properties and antimicrobial property was attained.
