摘要：

Two types of electric elastomers were prepared by dispersing a uniform mixture of starch particles and silicone oil into 107 silicone rubber in the absence and presence of a curing electric field, respectively. The elastic modules were tested with dynamic mechanical analysis with the round disk compression clamp. The results indicate that the storage modulus sensitivity attains a maximum value of 0.55 at a mass ratio of I between silicone oil and 107 silicone rubber with the given starch concentration. When the mass ratio is I and the starch concentration is 10 wt%, the storage modulus of the A-elastomer without the electric field is 37.1 kPa, while that of the B-elastomer with the electric field is 127.9 kPa. The storage modulus sensitivity attains a maximum value of 2.44. (C) 2008 Elsevier Ltd. All rights reserved.
