that changes the hydrogen bonding between the whiskers within the polymer matrix,
and at the same time presumably also impacts the whisker/matrix interactions.

10.5 Conclusion

For a i ber-reinforced composite, the i nal performance depends on i ber aspect ratio,
surface area and its uniform dispersion in the polymer matrix. h e fact that the cel-
lulosic nano/microcomposites show superior performance even at very low load-
ing makes them a desirable candidate in composite industry. However, retaining the
nanodimension and uniform dispersability in polar polymer matrix, especially in non-
polar matrix, is a huge challenge. Many methods have been adopted to overcome these
issues. Extensive research in this i eld in the last few years has given a clear idea on the
techniques to be adopted to attain stable nanoi bers. Pretreatment of i bers, such as dif-
ferent physical and chemical techniques, are found to improve i ber-matrix interaction.
h ese methods combined with proper processing techniques can result in the develop-
ment of cellulose nano/microcomposites with excellent properties.
