We report the surface grafting of octylamine onto a poly(ethylene-alt-maleic anhydride) (PEMA) gate insulator for enhancing the performance of dinaphtho[2,3-b:2′,3′-f]thieno[3,2-b]thiophene (DNTT) thin-film transistors.

The aim of this study was to investigate the effects of compatibilising agent and surface modification of short pineapple leaf fibre on physical properties of short pineapple leaf fibre reinforced high impact polystyrene (HIPS) composites. The purpose of using the compatibilising agents in this study was to modify the HIPS which include the polystyrene-block-poly(ethylene-ran-butylene)-block-poly(styrene-graft-maleic anhydride) and poly(styrene-co-maleic anhydride). Meanwhile, the alkali treatment was also used to modify the natural fibre surface of short PALF. The results have shown that adding compatibilising agent has improved the physical properties of the composites more effectively than by only using alkali treatment to modify the natural fibre surface.

Maleic anhydride modified polycarboxylates superplasticizes (MPC) was synthesized from allylic poly (ethylene oxide ether) (APEG), maleic anhydride (MAH), sodium methylallyl sulfonate (SMAS) using ammonium persulfate (APS) as initiator. The optimal MPC with best fluidity was got at 90 °C when molar ratio of MAH, APEG, SAMA was 2.75∶1∶0.4 in the present of 4.5 mol% APS of all the monomer molars. MPC which possessed hydroxyl terminated side chains shows some difference in fluidity retarding related to the conventional superplasticizers possessed methoxy terminated side chains.
