Atomic force microscopy investigation of electron beam (EB) irradiated composites based on biodegradable polymers and coconut fiber

摘要: The problem of environmental pollution caused by plastic waste can be solved the development biodegradable polymeric materials [17]. In this sense, poly(L-lactic acid) (PLLA) and poly(e-caprolactone) (PCL) have been receiving much attention lately due to their biodegradability in human body as well soil, biocompatibility, environmentally friendly characteristics non-toxicity [2, 6, 7, 10]. controlled degradation polymers is sometimes desired for biomedical applications purposes. PLLA a hard, transparent crystalline polymer [15]. On other hand, PCL used plasticizer because its ability lower elastic modulus soften [7]. original reasons preparing blends are reduce costs combining high-quality with cheaper (although approach usually accompanied drastic worsening properties polymer) create that has combination different components. However, according Michler [14], incompatible. Improved only realized if blend exhibits optimum morphology. According Sawyer [21], science, term morphology generally refers form organization on size Atomic force microscopy investigation electron beam (EB) irradiated composites based coconut fiber* Yasko Kodama, Akihiro Oishi, Naotsugu Nagasawa, Kazuo Nakayama, Masao Tamada, Luci D.
