Disclosed is a compound material comprised of a polymer body having multiple interconnected cavities formed thereon, multiple nano balls embedded in the polymer body and active compositions containing in the nano balls. In the compound material of the invention, the nano balls have multiple interconnected cavities and high ratio superficial measures for increasing the carrying load of active compositions adhered thereto. Further, the diameters of the nano balls are no less than the cavity diameters of the polymer body for controlling the release of active compositions and thus are applicable for medicine carriers, especially for medicines of the intestines.本發明係關於一種複合材料,該複合材料包括:具有連通至本體表面之複數孔穴的聚合物本體;包埋於該聚合物本體中的複數奈米球;以及包含於該奈米球之孔洞中的活性成分。本發明之複合材料中,由於該複數奈米球具有複數孔洞,具有高比表面積,可增加其吸附之活性成分的搭載量。此外,由於該複數奈米球的粒徑不小於該聚合物本體之孔穴的孔徑,可達到控制活性成分的釋出,應用於藥物載體,特別適用於腸道的藥物載體。
