| 在PDMAEMA聚合物的IR光谱中(见Fig.S1, Supplementary data)，在1732.32 cm-1的吸收峰指认为酯羰基的伸缩振动峰(C=O)，1150.34 cm-1的吸收峰对应为C-O-C的伸缩振动，甲基的C-H伸缩振动峰出现在2960 cm-1，2918 cm-1和2853 cm-1等处。与PDMAEMA的IR光谱相比，在PDMAEMA/PVA复合薄膜的IR光谱(见Fig.S1)中，C=O和C-O-C的伸缩振动峰出现在相似位置，未发生位移，同时在3418 cm-1处出现强的吸收峰峰，指认为复合膜中PVA的OH伸缩振动峰，这说明在PDMAEMA聚合物中成功加入PVA形成了复合材料。 |

| In IR spectrum of PDMAEMA (as shown in Fig. S1), the absorption peaks appearing at 1732.32, 1150.34, and 2960 cm-1 are attributed to the stretching vibration of carboxyl group C=O, C-O-C, and methyl group C-H, respectively. PDMAEMA/PVA films present the same C=O and C-O-C absorption peaks as those of PDMAEMA. Meanwhile, a new absorption peak found at 3418 cm-1 is due to hydroxyl group –OH stretching of PVA. IR spectra results give supporting evidence that the PDMAEMA have been successfully added into PVA. |

| IR spectra of PDMAEMA polymer was examined（Fig.S1, Supplementary C=O），1150.34data)，the peak at 1732.32 cm-1 was considered as the stretching vibration of C=O(the stretching vibration of C-H appeared at 2960 cm-1,the absorption peak occurred at 2918 cm-1 and 2853cm-1 were considered as the stretching vibration of C-O-C,respectively.The stretching vibration peaks of methyl appeared at the analogous position simultaneous 3418C=O and cm-1 et al).Compared with IR spectra of PDMAEMA,the existed stretching vibration of OH in the IR spectra of PDMAEMA/PVA composite films(fig.S1),this indicated that the composite material was succesfully fabricated via adding PVA into PDMAEMA polymer. |
