摘      要：Laser-induced graphitization(LIG)is a method of converting a carbon-rich precursor into a highly conductive graphite-like carbon by laser *** method has shown great promise as a versatile and low-cost patterning *** we show for the first time how an ink based on cellulose and lignin can be patterned using screen printing followed by laser *** printing is one of the most commonly used manufacturing techniques of printed electronics,making this approach compatible with existing processing of various *** use of forest-based materials opens the possibility of producing green and sustainable ***-patterning of the ink enables carbon patterns without residual precursor between the *** investigated the effect of the ink composition,laser parameters,and additives on the conductivity and structure of the resulting carbon and could achieve low sheet resistance of 3.8Ωsq^(−1) and a high degree of *** demonstrated that the process is compatible with printed electronics and finally manufactured a humidity sensor which uses lignin as the sensing layer and graphitized lignin as the electrodes.
