Focusing on the foundational theories of thermotropic and lyotropic liquid crystals, this book offers a comprehensive derivation that connects both frameworks through classical density functional theory (DFT). It simplifies the understanding of uniaxial nematic liquid crystals, guiding readers through the principles of phase behavior, molecular alignment, and the roles of entropy and energy. With an emphasis on the Maier-Saupe and Onsager theories, the text includes exercises to reinforce concepts, making it an excellent resource for students and practitioners seeking clarity in this complex field.
