The invention describes shape changing membranes that can be precisely controlled using the unique approach of smectic liquid-crystalline elastomers (LCEs) with patterned electrodes and a process of preparing and creating the elastomers. The methods to create the shape changing membranes is based on the electroclinic effect of smectic layers in a polymer network and provides a novel material for actuators.

The present invention is a method for releasing an active agent into a use nvironment, by disposing this active agent within the lumen of a population of tubules, and disposing the tubules into a use environment, either directly or in some matrix such as a paint in contact with the use environment. The tubules have a preselected release profile to provide a preselected release rate curve. The preselected release profile may be achieved by controlling the length or length distribution of the tubules, or by placing degradable endcaps over some or all of the tubules in the population, or by combinations of these methods. The invention is also a population of tubules having a preselected release profile to provide a preselected release rate curve.
