In　this　work,　a　gemini-surfactant　(i.e.　sodium　dilauramino　cysteine,　SDLC)　stabilized　high　internal　phase　emulsion　(HIPE)　template　was　utilized　to　prepare　monolithic　polyHIPEs　of　chitosan-g-polyacrylamide　(CT-g-PAAm)　for　the　first　time.　The　influences　of　internal　phase　fraction　and　emulsifier　concentration　on　the　porous　structures　were　studied.　The　morphologies　of　polyHIPEs　were　observed　via　scanning　electron　microscope　(SEM)　while　structure　parameters　were　investigated　by　combining　nitrogen　adsorption/desorption　measurements　with　mercury　intrusion　porosimetry　(MIP).　Highly　porous　polyHIPEs　of　CT-g-PAAm　with　porosity　varying　from　86　to　93%　were　obtained　at　different　internal　phase　fractions.　PoIyHIPEs　were　also　prepared　using　Tween　20　as　the　emulsifier　for　comparison.　It　was　found　the　polyHIPE　using　SDLC　emulsifier　(S-polyHIPE)　showed　higher　porosity　and　consequent　smaller　foam　density　than　that　using　Tween　20　emulsifier　(T-polyHIPE),　implying　the　gemini-surfactant　can　act　as　a　novel　type　of　promising　emulsifier　for　the　preparation　of　porous　polyHIPEs.　In　addition,　the　adsorption　performances　of　polyHIPEs　were　evaluated　by　adsorbing　methylene　blue　(MB).　At　the　same　internal　phase　fraction,　S-polyHIPE　showed　higher　adsorption　capacity　and　faster　adsorption　rate　than　T-polyHIPE.　The　adsorption　data　were　analyzed　by　isotherm　models　and　dynamic　models,　respectively.　The　results　indicated　that　the　adsorption　occurs　as　a　monolayer　on　the　adsorbent　surface　with　equal　adsorption　sites.
