(A) The film thickness, in air at 25°C (■), in water at 40°C (○) and in water at 25°C (●), of various APTES/pNIPAAm blend films cured in a vacuum oven at 160°C for 3 days and then rinsed by cold DI water. (B) The swelling, or thickness, ratio of these films in water at 25°C to 40°C. The error bars are the standard deviations of three measurements (on two samples of each type of film).
