Abstract

Correction for ‘Hierarchically porous polystyrene membranes fabricated via a CO2-expanded liquid selective swelling and in situ hyper-cross-linking method’ by Haozong Wang et al., RSC Adv., 2015, 5, 68639–68645.


In the original article, the data presented in Fig. 4 and 5b of the main article and in Fig. S2 of the ESI were not collected for the material presented in this paper. For this reason, revised versions of Fig. 4 and 5b that correspond to the material presented in this paper are included herein. A new ESI file that contains a correspondingly updated Fig. S2 has been uploaded for the original article; this replaces the version originally uploaded on 12th August 2015.

Fig. 5 (b) TEM image of the hyper-cross-linked PS membrane.

Additionally, the last sentence of the Results and discussion section should be changed as follows (the changes are in bold for clarity):

“The residual weight of the hyper-cross-linked PS membrane at 550 °C is 28.5%, much higher than that of the uncross-linked membrane”.

In the Materials and methods section entitled ‘Hierarchically porous polymeric membranes via hyper-crosslinking’, “FeCl3 (1.625 g, 0.005 mol)” should be corrected to “FeCl3 (1.625 g, 0.01 mol)”.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
