In this paper, we shall study the initial-boundary value problem of a chemotaxis model with signal-dependent diffusion and sensitivity as follows
$ \begin{cases} u_t = \nabla\cdot(\gamma(v)\nabla u-\chi(v)u\nabla v)+\alpha u F(w) +\theta u-\beta u^2, &x\in \Omega, \; \; t>0,\\ v_t = D\Delta v+u-v,& x\in \Omega, \; \; t>0,\\ w_t = \Delta w-uF(w),& x\in \Omega, \; \; t>0,\\ \frac{\partial u}{\partial \nu} = \frac{\partial v}{\partial \nu} = \frac{\partial w}{\partial \nu} = 0,&x\in \partial\Omega, \; \; t>0,\\ u(x,0) = u_0(x), v(x,0) = v_0(x),w(x,0) = w_0(x), & x\in\Omega, \end{cases} \;\;(*)$
in a bounded domain
$ \Omega\subset \mathbb{R}^2 $
with smooth boundary, where
$ \alpha,\beta, D $
are positive constants,
$ \theta\in \mathbb{R} $
and
$ \nu $
denotes the outward normal vector of
$ \partial \Omega $
. The functions
$ \chi(v),\gamma(v) $
and
$ F(v) $
satisfy
$ (\gamma(v),\chi(v))\in [C^2[0,\infty)]^2 $
with
$ \gamma(v)>0,\gamma'(v)<0 $
and
$ \frac{|\chi(v)|+|\gamma'(v)|}{\gamma(v)} $
is bounded;
$ F(w)\in C^1([0,\infty)), F(0) = 0,F(w)>0 \ \mathrm{in}\; (0,\infty)\; \mathrm{and}\; F'(w)>0 \ \mathrm{on}\ \ [0,\infty). $
We first prove that the existence of globally bounded solution of system (*) based on the method of weighted energy estimates. Moreover, by constructing Lyapunov functional, we show that the solution
$ (u,v,w) $
will converge to
$ (0,0,w_*) $
in
$ L^\infty $
with some
$ w_*\geq0 $
as time tends to infinity in the case of
$ \theta\leq 0 $
, while if
$ \theta>0 $
, the solution
$ (u,v,w) $
will asymptotically converge to
$ (\frac{\theta}{\beta},\frac{\theta}{\beta},0) $
in
$ L^\infty $
-norm provided
$ D>\max\limits_{0\leq v\leq \infty}\frac{\theta|\chi(v)|^2}{16\beta^2\gamma(v)} $
.
