Abstract

Controlling the adhesion of the polymer surface is a key issue in surface science, since polymers have been a commonly used material for many years. The surface modification in this study includes two different aspects. One is to enhance the hydrophilicity and the other is to create the roughness on the PET film surface. In this study we developed a novel and simple approach to modify polyethylene terephthalate (PET) film surface through polymer blending in twin-screw extruder. One example described in the study uses polyethylene glycol (PEG) in polyethylene terephthalate (PET) host to modify a PET film surface. Low content of polystyrene (PS) as a third component was used in the system to increase the rate of migration of PEG to the surface of the film. Surface enrichment of PEG was observed at the polymer/air interface of the polymer film containing PET-PEG-PS whereas for the PET-PEG binary blend more PEG was distributed within the bulk of the sample. Furthermore, a novel method to create roughness at the PET film surface was proposed. In order to roughen the surface of PET film, a small amount of PKHH phenoxy resin to change PS/PET interfacial tension was used. The compatibility effect of PKHHmore »« less

The compatibility effect of PKHH causes the formation of smaller PS droplets, which were able to migrate more easily through PET matrix. Consequently, resulting in a locally elevated concentration of PS near the surface of the film.

Effect of compatibilizer on impact and morphological analysis of recycled HDPE/PET blends

Journal Article Salleh, Mohd; Ahmad, Sahrim; Ghani, Mohd; ... - AIP Conference Proceedings

Blends based on recycled high density polyethylene (rHDPE) and recycled polyethylene terephthalate (rPET) were prepared using a corotating twin screw extruder. PET and HDPE are incompatible polymers and their blends showed poor properties. Compatibilization is a step to obtain blends with good mechanical properties and in this work, ethylene glycidyl methacrylate copolymer (E-GMA) was used as a compatibilizing agent. The effect of blends based on rHDPE and rPET with and without a compatibilizer, E-GMA were examined. From the studies clearly showed that the addition of 5% E-GMA increased the impact strength. SEM analysis of rHDPE/rPET blends confirmed the morphological interactionmore »« less

Conversion of Ocean Plastic Waste into Economically Viable Filaments and Fibers

Technical Report Kelly, Jesse; Hendren, Keith

There are increasing legislative, social, and environmental factors motivating protection of the environment, including the oceans. Ocean plastic wastes (OPW) are now recognized as one of the most serious environmental issues for marine wildlife. Ingestion of plastic debris or entanglement has been recorded in 44-50% of all seabirds,2 all species of sea turtles, otters and fish. Past estimates suggest that between 4.8 and 12.7 million metric tons of plastic entered the oceans in 2010. Currently, there are more than 30 trillion plastic particles floating on the surface of the oceans. The Department of Energy (DOE) is interested in conversion technologiesmore »« less
Exploration of fibers produced from petroleum based-mesophase pitch and pet blends for carbon fiber production

Journal Article Scherschel, Alexander; Harrell, Timothy; Sushchenko, Andre; ... - Journal of Polymer Research

Petroleum-derived mesophase pitch and polyethylene terephthalate (PET) were blended and melt-extruded to create precursor fibers. The raw blends, heat treated bulk materials, and fibers were all examined to determine compatibility between petroleum-derived mesophase pitch and PET. Thermal investigation of the raw blends showed the presence of both the pitch and PET in separate phases suggesting no interactions had occurred during mixing. Here, the heat-treated bulk material also showed multiple phases under polarized light while Fourier-transform infrared spectroscopy indicated that the two materials did not fully separate during extrusion. Elemental scans of the precursor fibers showed areas of high oxygen concentrationsmore »« less

Aramid Copolymers as Reinforcing Compatibilizers for Mixed Plastics Recycling

Technical Report Kelly, Jesse

Plastics recycling faces challenges in the form of costs associated with maintaining the purity of waste feedstocks and reprocessing them into useable forms – principally the cost of mechanical separation of waste plastics from one another. This has been considered a largely unavoidable cost due to issues that arise in mixed-plastics systems: immiscibility issues, phase separation, and the degradation of mechanical properties due to incompatibilities. Additionally, mechanical recycling tends to yield a product that displays degraded properties even when pure waste streams are procured and kept free of contaminants. As such, a method of upcycling plastic waste streams both inmore »« less
Enhancing the Melt Strength of Poly(Lactic Acid) via Micro-Crosslinking and Blending with Poly(Butylene Adipate-co-Butylene Terephthalate)for the Preparation of Foams

Journal Article Zhang, Rong; Cai, Chang; Liu, Qingting; ... - Journal of Polymers and the Environment

The melt strength of poly(lactic acid) (PLA) is an important factor in preparing foams and blowing films. Aiming to endow PLA with a suitable melt strength via a slight crosslink, a superficial micro-crosslinking method was introduced in which the PLA feed was mixed with benzoyl peroxide (BPO) and crosslinked in a 100 °C oven for 1 h. Additionally, poly(butyleneadipate-co-terephthalate) (PBAT) was blended with the crosslinked PLA (C-PLA) to further improve melt strength and viscosity. The blend foams were prepared using a single-screw extruder and azodicarbonamide as a foaming agent. The properties were characterized by gel fraction, melt flow rate (MFR), rheometry, DSCmore »« less
