This work tries to find out thick brane solutions in braneworld scenarios described by a real scalar field in the presence of a scalar-kinetic term F ( X , ϕ)= X ϕ m with a single extra dimension, where stands for the standard kinetic term and m =0, 1, 2... . We mainly consider bent branes, namely de Sitter and anti-de Sitter four-dimensional slices. The solutions of a flat brane are obtained when taking the four-dimensional cosmological constant Λ 4 →0. When the parameter m =0, these solutions turn to those of the standard scenario. The localization and spectrum of graviton on these branes are also analyzed.
