“…Evidently, this may suggest slight antimicrobial activity of PEI/TiO 2 BNC buried in the soil. Some other experiments also showed that the antimicrobial activity of the nano-TiO 2 composites increases with increasing concentration [39] and higher antimicrobial behavior will reduce biodegradation of the polymer in the soil. It may be recommended that for synthesis of biocompatible polymers, low concentration of TiO 2 must be used.…”

Abstract. A new chiral poly(ester-imide) (PEI) was prepared via direct polyesterification of N,N!-(pyromellitoyl)-bis-(L-tyrosine dimethyl ester) and N-trimellitylimido-L-methionine using tosyl chloride/pyridine/N,N!-dimethylformamide system as a condensing agent. The resulting new chiral polymer was obtained in good yield and had good thermal stability as well as good solubility in common organic solvents. After that, PEI/titanium bionanocomposites (PEI/TiO 2 BNCs) were prepared using the modified nanosized TiO 2 via sonochemical reaction that can accelerate hydrolysis, increase collision chance for the reactive system and improve the dispersion of the nanoparticles in polymer matrix. The scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) results indicated that there is no aggregation of a large quantity of particles. Thermogravimetric analysis (TGA) confirmed that the heat stability of the BNC polymers in the temperature range of 400-800ºC was enhanced by addition of TiO 2 nanoparticles. Furthermore, in vitro toxicity test was employed for assessing the sensitivity of these compounds to microbial degradation. To this purpose, polymer and PEI/TiO 2 BNCs were investigated under soil burial conditions. The results of this study revealed that polymer and its BNCs are biologically active and non-toxic in the natural environment although some antimicrobial properties were found for BNCs.

INFO ARTIKEL ABSTRAK Sejarah artikel:Penelitian ini bertujuan untuk mengetahui pengaruh kadar dioktil ftalat (DOP) terhadap sifat fisis dan mekanis kulit sintetis berbahan baku polivinil klorida (PVC). Kulit sintetis dibuat dari bahan resin PVC jenis emulsi dengan penambahan bahan aditif DOP sebagai pemlastis, BaCd sebagai penstabil, dan CaCO 3 sebagai bahan pengisi, serta pigmen untuk pewarna lapisan atas. Kulit sintetis dibuat dengan 4 lapisan, yaitu lapisan poliuretan (PU), lapisan atas, lapisan dasar, dan kain penguat twill weave. Lapisan PU ditambahkan untuk memberikan sifat tahan abrasi, fleksibilitas tinggi, dan tahan pengusangan. Untuk membuat permukaan menyerupai kulit asli digunakan kertas embos. Pada penelitian ini DOP divariasi jumlah penambahannya pada lapisan atas berturut-turut 45, 50, 55, 60, dan 65 bagian. Ketebalan lapisan PU 0,1 mm, lapisan atas 0,6 mm, lapisan dasar 0,1 mm, dan kain penguat 0,3 mm. Kulit sintetis hasil percobaan diuji sifat-sifat fisis dan mekanisnya meliputi kekuatan tarik, kemuluran, ketahanan sobek, ketahanan rekat, ketahanan luntur warna terhadap gosokan, ketahanan terhadap pelekatan, ketahanan terhadap temperatur rendah, dan ketahanan terhadap pengusangan. Kulit sintetis yang mempunyai sifat fisis dan mekanis yang optimal adalah kulit sintetis yang mengandung DOP 55 bagian pada lapisan atas. PendahuluanIndustri lembaran plastik khususnya lembaran kulit sintetis telah berkembang pesat sehubungan dengan peningkatan permintaan bahan sandang dan perabot rumah tangga seperti jaket, ikat pinggang, sepatu, tas, koper, kursi sofa, jok mobil, dan sebagainya, yang sulit dipenuhi oleh bahan baku kulit asli karena terbatasnya ketersediaan kulit. Selain terbatasnya bahan baku kulit, harga produk kulit yang relatif lebih mahal dan isu
