Experimental Details Materials.
As the two materials, core and shell are of different materials, the cooling would dissipate different heat energy if it was compared with that of non-encapsulated TCM.

Classification of ecological clothing materials There are various types of new ecological raw materials developed in recent years, and they can be divided into natural fiber material and regenerated fiber material, as is shown in Fig. 1.
According to the introduction in the magazine of Fiber Science in Japan, the circulation period of regeneration for starch which is the raw material of corn fiber is short, about 1 to 2 year (s).

Preparation and Characterization of Al/Pb Layered Composite Materials Shenggang Zhou 1,a, Peixian Zhu 1,b, Yong Sun 2,c and Lida Sun 3,d 1Faculty of Material Science and Engineering, Kunming University of Science and Technology, Kunming, Yunnan, 650093, China 2Key Lab of Advanced Materials of Precious-Nonferrous Metals of Yunnan Province, Kunming, Yunnan, 650091, China 3College of science, Honghe University, Mengzi, Yunnan, 661100, China.
Microstructure of the layered composite materials was studied by scanning electron microscope (SEM) and Energy Dispersive Spectrometer (EDS), and then the flexural strength and interface adhesion of the layered composite materials were measured.
The surface of Al-Sn-Pb layered composite materials are observed by SEM, EDS after etch polishing.
