Nano cellulose or cellulose nanofibers (CNF) material is composed of Nano sized cellulose fibrils with a high aspect ratio and typical lateral dimensions are 20–50 nm. Its pseudo-plastic characteristics exhibit the property of certain gels or fluids (viscous) and over a period of time, becomes, Thixotropic. The ability of CNFs to go into a PDLC ultrasonically with a helical arrangement results in dried CNF films. The films thus acquire attractive thermal properties, creating possibilities for their use in various applications. In this presentation, we discuss the thermal behavior of Nano cellulose doped in PDLC that governs the formation of the desired helical structure. By comparison with the corresponding self-assembly processes of other rod-like nanoparticles, for example, carbon nanotubes particles, we outline in the present paper the variation in the number of mesogen phases in varying compositions of Nano Cellulose doped PDLCs.

The main focus this research involved the absorption spectroscopy of nanocellulose doped polymer dispersed liquid crystal (PDLC). the nanomaterial doped PDLC have superior performance relative to conventional PDLCs materials due to their high strength & high stiffness in polymer reinforcement. Nano cellulose doped PDLCs with different composition have been studied by the means of UV-VIS (Ultravoilet visible spectroscopy). A solution composed of methylmeta- acrylate (MMA) & nematic LC (5CB) were prepared by solution casting toluene. results were interpreted in terms of infrared absorption spectrum, optical properties & solubility of LC in polymer matrix.
