In order to obtain self\u2010assembled structures with even smaller sizes, it is necessary to design high\u2010\n                    <jats:italic>\u03c7<\/jats:italic>\n                    BCPs. It is known that the properties of rod blocks and coil blocks are quite different. Theoretically, microphase separation will occur when\n                    <jats:italic>\u03c7N<\/jats:italic>\n                    value is greater than 5 for rod\u2010coil BCPs. Therefore, ordered structures can be formed even when the total polymerization degree is small. In this work, BCPs containing polydimethylsiloxane (PDMS) as a coil block and a rod block, poly[4\u2032\u2010(methoxy)\u20102\u2010vinylbiphenyl\u20104\u2010methyl ether] (PMVBP), are synthesized. Small\u2010angle X\u2010ray scattering (SAXS) is used to characterize the bulk self\u2010assembled structures of the BCPs.

In addition, a LAM structure with a minimum periodic size of 9.34 nm is obtained.
