The coating efficiency of starch on clay particle surfaces was investigated by measuring the dissolved starch in the supernatant. The experimental results indicated that more than 98% of the applied starch was precipitated onto the surface of the filler, and the resulting starch—fatty acid-clay composites had relatively good resistance against moderate shear force. The morphology, particle size, and ξ potential of the starch modified filler were also determined with scanning electron microscopy, Malvern particle size analyzer, and Malvern Zetasizer, respectively. An aqueous slurry of linerboard pulp containing 5―5 wt % modified fillers was used for handsheet preparation, and the effects of the addition of modified filler on the paper properties were studied. At a dosage of 10% of the modified filler (based on filler), the retention of the filler was higher than 75%. The strength properties of paper with starch modified fillers were improved by approximately 15% when compared against those of paper with unmodified fillers.
