In this paper, a series of semi-interpenetrating polymer network materials based on poly ((2-dimethylamino) ethyl methacrylate)/poly (N, N-diethylacrylamide) (PDMAEMA/PDEA) were synthesized at room temperature. The influence of this additive on the property of resulting PDEA materials was investigated and characterized. The glass transition temperature (Tg) of the semi-IPN materials was observed by Differential Scanning Calorimetry (DSC). Compared to PDEA, the semi-IPN materials exhibited excellent mutative values in response to an alternation of the temperature, and showed fast swelling and deswelling rates in response to temperature change, which suggests that these materials have potential application as thermal infrared camouflage materials.

Thermal infrared camouflage refers to a series of camouflage patterns for coping with modern thermal infrared reconnaissance. In order to solve the problems that the subjectivity of traditional evaluation methods on ground thermal infrared camouflage and correlation constraint is not easy to test and so on. The effect factors of thermal infrared camouflage were analyzed, the index system of model of ground thermal infrared camouflage was established, and based on it, the dynamic DEA (data envelopment analysis) model was applied to evaluate the ground thermal infrared camouflage. The example shows that the method in this paper can be applied to compare the DMUs (decision making units) efficiently and it can select the best DMU.

Infrared Camouflage

In order to reduce the difference in radiant intensity between background and military targets, such as road or surface of building decorated with concrete, based on the law of Stephen-Boltzmann, the influence of emissivity or temperature on radiant energy was analyzed, phase change materials (PCMs) were employed in adjusting or controlling radiant energy from military targets from the point of temperature, then the low-detective probability of the target was achieved.

For coping with modern thermal infrared reconnaissance, thermal infrared camouflage is becoming the hotspot of camouflage pattern research. Concerning the traditional methods on evaluating ground thermal infrared camouflage can’t solve the “dynamic” problem and the pure technical as well as pure scale efficiency. This article established new models to figure it out. The new measure introduced time parameter to construct dynamic model, then it set up pure technical dynamic DEA model which supposed it had variable returns to scale. Through the relationship among technical, pure technical and pure scale DEA model, we can get the pure scale dynamic DEA model. Finally, an example was calculated which shows the application of the new models.
