In the past few years, there have been many attempts to commercialize Polymer Dispersed Liquid Crystal (PDLC) for Rear Projection Screen (RPS) in electrically switchable films and glass products. This application is based on the exceptional image quality of PDLC at a wide viewing angle. However, due to the high price of conventional switchable PDLC privacy glass, the integration of RPS in PDLC failed to attract large multimedia and entertainment markets. An obvious solution to this problem is the independent develo [...]

Technical lignins from the biorefinery, pulp, and paper industries are largely underutilized, even though this aromatic and randomly structured biopolymer could be an interesting raw material for advanced applications in addition to bulk daily goods. Recently, colloidal lignin particles (CLPs) have gained much of the research interests due to the attractive multi-functional properties of the biopolymer. Utilization of lignin in nanoparticulate morphology resolves most of the drawbacks when using lignin (heterogenei [...]
