Surface appearance is one of the most important properties of many products. It must be tailored to the product needs which are frequently very different in various applications.
This book is devoted to additives used for surface modification of materials a technology used in the production and processing of adhesives, appliances, automotive, bookbinding, building and construction, business machines, caulks, cellular phones, coatings, concrete, dental applications, electronics, flooring, footwear, furniture, graphic arts, hot-melt adhesives, hygiene, labels, lacquers, leather, lithographic inks, medicine, nanofluids, nonwovens, optical films, packaging, paints, paper, plastics, pressure-sensitive adhesives, printing inks, rubber, sealants, sporting goods, tapes, varnish, wire and cable, wood and many other materials. This book is the first known published book on this subject.
Handbook of Surface Improvement and Modification contains information on ten groups of additives which are commercially available for improvement and surface modification of manufactured materials. These include additives improving scratch and mar resistance, gloss, surface flattening, tack reduction, tack increase (tackifiers), surface tension reduction and wetting, surface cleaning, hydrophobization, anti-cratering and leveling, and coefficient of static friction. They are discussed in the separate chapters in the same order as above.
The highlights for each chapter are, as follows
Scratch and mar resistance: many important influences combined form mechanism of protection; scratch features (ironing, transition, stick-slip, tearing) determination; texture patterning and scratch visibility; self-healing; damage observation on nanoscale; violet laser scanning confocal microscope cross-section profile of scratch damage; silsesquioxanes
Gloss enhancement: magnetic resonance imaging measurements of human brain reactions; instrumental measurements; meso- and micro-scale roughness; hyperbranched resins; durability of gloss
Surface matting: powder coatings; roughness formation; dull black coatings; curing rate and flattening; low-gloss soft-touch; anti-glare coatings
Tack-free: abhesion features; instrumental surface tack measurement; surface tension; nature inspired; completeness of cure; dental applications
Tackifiers: balance of elastic and viscous properties; structure and origin of rosins; phase structure of tackifying system; compatibility; environmental solutions; pharmaceutical, cosmetics, and medical applications
Surface tension and wetting: bottlebrush polymers; rigid-rod polymeric fiber; superhydrophobicity; superhydrophilicity; surface tension prediction; porosity and morphology; wettability surface gradient; surface free energy; bacterial adhesion; photo-induced hydrophilicity; orthopedic implants; high-speed printing; dry-erase inks
Surface cleaning and stain inhibition: in-source cleaner regeneration; negative impact of perfluorinated acids; bio-inspired cleaning methods; hole generation and pollutant decomposition; photocatalytic self-cleaning; anti-graffiti coating, graffiti removal
Water repelling: biomimetic solutions; superhydrophobic coatings; self-hydrophobization; superamphiphobic surfaces; chemical functionalization, microtextured surface; building structure protection; protection against ice formation
Anti-cratering and leveling: thixotropic behavior; nanoparticles; leveling agents; superplasticizers; powder coatings; sag-leveling balance; pinhole prevention
Coefficient of friction: tribometers; speed effect; dwell time effect; surface patterns and textured surfaces; elemental mapping; capillary bridge; human skin; dangling bonds; polymer brushes; lamellar tribofilm; microspheres, release agents; film with consistent coefficient of friction
A companion book entitled Databook of Surface Modification Additives has also been published. It contains information and data on the additives commercially available to improve materials by the above-listed modifications. Both books do not repeat information. In this book, the focus is on the methods and mechanisms which are known to be responsible for the enhancement of material properties with the use of additives.
