Based on the degenerate Darboux transformation, the n-order smooth positon solutions for the derivative nonlinear Schrodinger equation are generated by means of the general determinant expression of the N-soliton solution, and interesting dynamic behaviors of the smooth positons are shown by the corresponding three-dimensional plots in this paper. Furthermore, the decomposition process, bent trajectory and the change of the phase shift for the positon solutions are discussed in detail. Additionally, three kinds of mixed solutions, namely (1) the hybrid of one-positon and two-positon solutions, (2) the hybrid of two-positon and two-positon solutions, and (3) the hybrid of one-soliton and three-positon solutions, are presented and their rather complicated dynamics are revealed.
