Samples with various molecular weights of PS-b-PEO and its blending ratio with TTIP

Sample name	S1	S2	S3	S4	S5
PS-PEO	58,500–37,000	58,500–37,000	58,500–37,000	60,000–14,500	58,600–71,000
TTIP/PEOa	3.87	5.16	10.32	3.64	3.70
Grain size (nm)b	10.7	12.5	14.9	11.8	13.5

^aTTIP/PEO represents the weight ratio between TTIP and PEO in PS-b-PEO

^bGrain sizes were calculated from XRD profiles shown in Fig. 2
