Book excerpt: In this work we have tried to relate the thermal bond strengths with the concepts of chain dynamics via interfacial adhesion development at symmetric polymer interfaces. To relate structural bond strengths with polymer chain dynamics we need a molecular connectivity relation. This requires relation of the microscopic dynamics of chains with macroscopic interfacial adhesion measurements. Previous literature does indicate that the nonwoven fabric strength reaches a maximum for a particular value of any of the following variables: temperature, contact time, pressure and quench rate, while the others are kept constant. The rationale for such a behavior has been supported in qualitative terms where a fundamental understanding of the polymer physics is lacking. The properties of reptation and diffusion of polymer chains to form effective entanglements and boost interfacial adhesion has been reviewed. The present work provides a useful compendium of valuable inter-relations between the effects of calendar speed and calendar temperature on interfacial bond strengths. The varying molecular weights of the polymer have been found to affect the thermal bonding process in previous studies. Our results for the effect of varying molecular weight on bond strengths have been found to be an extension to Wool's work beyond a critical molecular weight. Interesting trends for the effect of molecular weight on interfacial adhesion have been presented.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research was to understand the bonding behavior of different polymers in thermal bonding. Special attention was given to the interaction of the materials variables with processing characteristics of the polymers. Initially, thermal bonding studies were done using films from different polymers. Polymer films of different morphology were produced from different grades of polypropylene. Thermal bonding of these films was carried out using the hot press. Effect of film structure, properties and bonding conditions on the bonding efficiency was studied. A range of bond temperatures covering poor, optimum and over bonding were studied to understand the changes taking place. Bonded film strength was analyzed using tensile testing. Change taking place to polymer in bond point and original surface were analyzed using SEM. Importance was given to material variables of bonding and their influence on the bond strength are scrutinized in this work. Films bonded at lower sealing pressure and time gave better results. Films with lower orientation formed better bond. Bonding studies on films were extended to fibers and webs. Polypropylene fibers manufactured with different processing conditions and with different cross-section, denier, and polymer melt-flow rate were bonded with different heat sealers. Bonding studies were also done with several sheath-core bi-component fibers. Fiber bond strength results were similar to results observed in case of films with respect to bonding temperatures studied. Carded webs were prepared from polypropylene and other bi-component fibers. Effect of bonding temperature on property of calendered web was determined using tensile, tear and stiffness testing. Fiber web mechanical properties increased with the calendering temperature. At higher calendering temperature strength increased along with the stiffness. After certain optimum temperature, properties of the webs deteriorated. Impact of spin finishes on the thermal bond strength was studied. Thermal bonding studies of polymer film, fibers and fiber webs with two different finishes at different concentration levels were carried out. In most of the cases, bond strength was lower compared to those without any finish, and the strength drop was higher with higher level of finish. Film, staple fiber and fiber web attained its optimum strength at slightly higher bonding temperature in the presence of finish.

Available in PDF, EPUB and Kindle. Book excerpt: Due to their unique size-dependent physicochemical properties, nanostructured thin films are used in a wide range of applications from smart coating and drug delivery to electrocatalysis and highly-sensitive sensors. Depending on the targeted application and the deposition technique, these materials have been designed and developed by tuning their atomic-molecular 2D- and/or 3D-aggregation, thickness, crystallinity, and porosity, having effects on their optical, mechanical, catalytic, and conductive properties. Several open questions remain about the impact of nanomaterial production and use on environment and health. Many efforts are currently being made not only to prevent nanotechnologies and nanomaterials from contributing to environmental pollution but also to design nanomaterials to support, control, and protect the environment. This Special Issue aims to cover the recent advances in designing nanostructured films focusing on environmental issues related to their fabrication processes (e.g., low power and low cost technologies, the use of environmentally friendly solvents), their precursors (e.g., waste-recycled, bio-based, biodegradable, and natural materials), their applications (e.g., controlled release of chemicals, mimicking of natural processes, and clean energy conversion and storage), and their use in monitoring environment pollution (e.g., sensors optically- or electrically-sensitive to pollutants)

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been a veritable explosion of research and development in consumer-oriented fields that utilize polymeric materials which absorb large amounts of water. These fields encompass the preparation, characterization and commercialization of separation systems, pharmaceutical and personal care products such as infant diapers, feminine products, incontinence products and many other related areas. The polymeric materials utilized in these applications are known as absorbent or superabsorbent materials because of their ability to swell rapidly and to retain large volumes of water, urine and other biological fluids.The aim of this book is to introduce the fundamentals of polymer structure and swelling as related to polymers used for these superabsorbent materials. In the field of absorbence, particular attention is given to crosslinked structures which swell to more than fifty times their initial weight in water or electrolytic solutions. The book also provides descriptions of novel applications of superabsorbent materials as well as a detailed analysis of water transport in crosslinked polymers.Absorbent Polymer Technology should be of interest to chemists, polymer scientists, chemical engineers, and industrial scientists working with swellable polymeric systems in personal care, pharmaceutical, agricultural waste treatment and separation industries.
