The tensile strength, 257.86 MPa, and modulus, 2.20 GPa of PDA-type homo-PI film are 2.4 and 1.6 times as large as those of CDA-type one, respectively. however, it's elongation value is smaller than that of CDA-type one.

Although the tensile strength (257.86 Mpa) and modulus (2.20 GPa) of the PDA-type homo-PI film are 2.4 and 1.6 times of those of the CDA-type one, respectively, its elongation value is lower than that of the CDA-type one. While the copolymer film well integrates the advantages of the two types of homopolyer in mechanical Properties .

Although the tensile strength (257.86 Mpa) and modulus (2.20 GPa) of the PDA-type homo-PI film are 2.4 and 1.6 times of those of the CDA-type one, respectively,the elongation value of the former is lower than that of the later. Furthermore, the copolymer film of PDA and CDA could  integrate the excellent mechanical properties of those homo-polymers.
