Abstract: This study proposed a rolltoroll (R2R) powder hot embossing process for the fabrication of microstructures on polymer film by combining the merits of R2R hot embossing process and powder metallurgy technology. An R2R powder hot embossing system was developed and a series of embossing experiments were conducted. The influences of processing parameters, which included mold temperature, feeding speed and applied force, had been investigated systematically by using the onevariableatatime (OVAT) method. It was found that the completelyfilled micropyramid arrays could be fabricated by R2R powder hot embossing process under the mold temperature of 130—145℃, the feeding speed of 0.2—0.8m/min and the applied force of 250—500N.

Key words: polymer film; microstructures; micropyramid arrays; rolltoroll (R2R) powder hot embossing; process parameters
