本研究為評估栗殼纖維(CSF)與聚丁二酸丁二醇酯(PBS)之複合材(PBS/CSF)，及經交聯反應之栗殼纖維(TCSF)與PBS接枝順丁烯二酸酐(PBS-g-MA)之複合材(PBS-g-MA/TCSF)之結構、機械性質、生物相容性與生物降解性。
研究發現PBS-g-GMA/TCSF相較於單純之PBS與PBS/CSF複合材，有較好的機械性質，可歸因於PBS-g-MA與TCSF之間擁有較佳之兼容性。將常人之包皮纖維細胞(FBs)接種於這兩種複合材上以測試生物相容性；結果顯示出，附著於PBS/CSF複合材上之FBs，其細胞增生率、膠原蛋白增生與細胞毒性測定，皆優於PBS-g-MA/TCSF複合材；而PBS-g-MA/TCSF複合材較PBS/CSF有較好的抗水性。另將兩種系列之複合材埋入土壤堆肥中測試後，皆有重量的損失，指出兩種複合材皆有生物降解性，且生物降解性會隨CSF濃度上升而升高。

The structural, mechanical, biocompatibility, and bio- degradability properties of composite materials formed of poly(butylenes succinate; PBS) and natural fiber (chestnut shell fiber; CSF) were evaluated. Maleic anhydride-grafted PBS (PBS-g-MA) and treated (crosslinked) CSF (TCSF) were used to improve the mechanical properties of PBS/CSF composites. The results show that PBS-g-MA/TCSF composites have superior mechanical properties compared with both pure PBS and PBS/CSF composites, which is attributed to better compatibility between the polymer and TCSF. Normal human foreskin fibroblasts (FBs) were seeded onto these two series of composites to characterize the biocompatibility. FB proliferation, collagen production, and cytotoxicity assays on the PBS/CSF series of composites exhibited superior results compared with those on the PBS-g-MA/TCSF composites. PBS-g-MA/TCSF was found to be more water resistant than PBS/CSF, and the weight loss of both the composites buried in soil compost indicated that both were biodegradable, especially at high levels of CSF substitution.
