Conductive Electroactive Polymers: Intelligent Materials Systems, Second Edition

From the authors' preface: "As we input the period of clever fabrics and embark upon a brand new method of fabric layout, synthesis, and process integration, convinced teams of fabrics will turn out to be champions. "Standing excessive between those champions are conductive electroactive polymers (CEPs), which seem destined to play a critical function within the improvement of clever fabrics.

The Linearized Theory of Elasticity

This ebook is derived from notes utilized in educating a first-year graduate-level path in elasticity within the division of Mechanical Engineering on the collage of Pittsburgh. it is a sleek therapy of the linearized idea of elasticity, that's awarded as a specialization of the overall thought of continuum mechanics.

Handbook of antiblocking, release, and slip additives

This instruction manual, now in its 3rd version, is the single entire reference on hand almost about antiblocking, unencumber, and slip ingredients, that are of excessive business significance. those ingredients are used to change the homes and function of polymers: minimizing adhesion, assisting separation, and bettering the potency and value of processing tools.

The kink on the surface tension isotherm at low surfactant concentrations can be related to the formation of the surfactant ‘‘pre-associations’’ in the system. 7 Isotherms of the surface tension of OP-10 solutions in DEG-1 at various conversion levels of the epoxy groups: (1) 5%, (2) 10%, (3) 20%, and (4) 30%. 7 shows that with increase in the degree of epoxy conversion, ‘‘pre-associations’’ occur at lower surfactant concentrations. The surfactant concentration at which ‘‘pre-micelles’’ and micelles are formed is related to the decline of surfactant solubility in the oligomer during its polymerization.

As Fig. 5 shows, in the early stages of the reaction there is an abrupt decrease of the particle concentration while their size does not change significantly. Once the concentration of the PR molecules formed exceeds CCMF, a decrease of the particle size is observed such that the size of the PR aggregates is smaller than that of OAA. The data permit an easy explanation of the regularities of the change in surface tension during the course of DEC-1 reaction with various quantities of OAA (Fig. 6).

The use of curing agents for polymeric adhesives and coatings with surface-active properties is of considerable interest. These include curing agents for epoxy resins like oligoamineamides (OAA) or versamides. Such substances change the surface tension of the epoxy resins and their wetting capacity is enhanced by the fatty alkyl chain and by the polar amine groups; in structure they are similar to detergents. The curing of epoxy resins by liquid polyamide resins gives products that have good wetting properties and better adhesion and elasticity compared with epoxy resins cured by polyamines.
