Crustacean chitin nanomaterial as reinforcement for bio-based polymer
In this study, chitin nanofibers with an average diameter of 80–100 nm were extracted from crab shell and used to reinforce bio-based polymer, polylactic acid (PLA). Solvent-casting and hot-compression moulding were used to fabricate chitin/PLA nanocomposite. Chitin nanofibers were first dispers...

description |
In this study, chitin nanofibers with an average diameter of
80–100 nm were extracted from crab shell and used to reinforce
bio-based polymer, polylactic acid (PLA). Solvent-casting and
hot-compression moulding were used to fabricate chitin/PLA
nanocomposite. Chitin nanofibers were first dispersed in PLA/
chloroform mixture before the solvent was left to evaporate
naturally, leaving behind chitin/PLA thin film composite.
Thicker specimen of composite was produced by filling the dogbone
mould cavities with chloroform-free chitin/PLA film followed
by compression moulding at 190°C and 25 bar. Tensile
strength tests were performed to evaluate the mechanical properties
of the nanocomposite at different chitin concentration
loading. Increase in chitin nanofiber content up to 5 wt.%
effectively improves the Young’s modulus (E) and tensile
strength (σ) of the resulting nanocomposite, of which the highest
improvement was found at 5% chitin loading (E = 1.3 GPa,
σ = 24 MPa). This account for 13% Young’s modulus and 275%
tensile strength improvement compared to neat PLA specimen
(E = 1.15 GPa, σ = 6.4 MPa). Further addition of chitin nanofiber
decreases the tensile strength performance of the nanocomposite
because of chitin-chitin agglomeration, which leads to poor
dispersion of the nanofibers within the PLA matrix |
