Chitin, next to cellulose, is the most abundant biopolymer found in nature. In recent years, its potential applications in several fields of research have been extensively studied for many reasons. It can be utilized as a waste product, since it is readily found as one of the main constituents in crustacean shells, making it very eco-friendly and inexpensive to manufacture. However, chitin’s use is limited due to its low solubility in organic solvents; so it is often modified to more practical structures, including chitosan and chitin nanowhiskers. This discussion focuses on two promising applications for chitin nanowhiskers: to improve the physical properties of concrete and for use in biomaterial research. The first of which analyzed how chitin nanowhiskers could be cross-linked with a plasticizer to increase the mechanical strength of concrete, while also decreasing its viscosity. The second project studied the effect that crosslinking nanowhiskers onto chitosan had on the improvement of its physical and mechanical properties of scaffolds. Fourier transform infra-red (FTIR) analysis was performed on pure chitin and chitin nanowhiskers to verify that the two were identical; and scanning electron microscopy (SEM) images were taken to show the difference between each, in terms in size and geometry. To determine the extent of cross-linking, these images were then compared to an FTIR analysis of the cross-linked nanowhiskers for each respective project. In addition, SEM photos were taken of the chitosan-chitin nanowhisker scaffolds and of pure chitosan scaffolds to evaluate any difference in pore size, shape, and distribution for the second study. Overall, the goal of this research is to determine how chitin nanowhiskers can be applied for real world applications.
