Abstract We present a study of the controlled biodegradation polylactic acid (PLA) reinforced with high lignin containing microfibrillated cellulose (MFLC) isolated from chemi-thermomechanical pulp. The surface MFLC was modified using an acetylation method to decrease its polarity. Biocomposites different and acetylated (Ac-MFLC) contents were fabricated via solvent casting method. biocomposite...

Abstract The aim of the present study is to develop a test method suitable for modelling thermoforming processes and which provides an index that accurately characterises thermoformability film or sheet at given temperature pressure. For this purpose, elevated pneumatic deformability was considered be most suitable. During test, blown until it tears, takes only few seconds. We recorded blowing ...

The goal of this research is to determine how tiredness behavior may be measured (PLA). A To variety technical data sets were S-N curves chosen and statistically re-analyzed. as described in the following section, generate a negative reference value reverse slope also an improved tolerance limit 106 2 failure cycles. average effect stress on fatigue can indicated via administering highest level...

Drug carrier biocompatible and biodegradable nanoparticles of about 15 nm were prepared by solvent evaporation technique from star-shaped poly(D,L-lactide) synthesized using dipentaerythritol as core and Tin (II) ethylhexanoate as catalyst.

We propose a new type of ammonia sensor based on composite film between polyaniline (emeraldine base) dissolved in dimethylformamide, and poly(DL-lactic) acid dissolved in chloroform. The two solutions were mixed in weight ratio of the components 1:1 and cast on Al2O3 substrate, on which silver electrodes were deposited previously. The active layer structure and morphology were examined by atom...
