With the ever-increasing amount of research being published it is a Herculean task to be fully conversant with the latest research developments in any field, and the arena of adhesion and adhesives is no exception. Thus, topical review articles provide an alternate and very efficient way to stay abreast of the state-of-the-art in may subjects representing the field of adhesion science and adheisves.

Based on the success and the warm reception accorded to the premier volume in this series "Progress in Adhesion and Adhesives" (containing the review articles published in Volume 2 (2014) of the journal Reviews of Adhesion and Adhesives (RAA)), volume 2 comprises 14 review articles published in Volume 4 (2016) of RAA.

The subjects of these 14 reviews fall into the following general areas:

1. Surface modification of polymers for a variety of purposes.

2. Adhesion aspects in reinforced composites

3. Thin films/coatings and their adhesion measurement

4. Bioadhesion and bio-implants

5. Adhesives and adhesive joints

6. General adhesion aspects

The topics covered include: surface modification of natural fibers for reinforced polymer composites; adhesion of submicrometer thin metals films; surface treatments to modulate bioadhesion; hot-melt adhesives from renewable resources; particulate-polymer composites; functionally graded adhesively bonded joints; fabrication of nano-biodevices; effects of particulates on contact angles, thermal stresses in adhesively bonded joints and ways to mitigate these; laser-assisted electroless metallization of polymer materials; adhesion measurement of coatings on biodevices/implants; cyanoacrylate adhesives; and adhesion of green flame retardant coatings onto polyolefins.

Abstract

Recent advances in engineering, natural fibers development and composites science offer significant opportunities for new, improved materials which can be biodegradable and recyclable and can also be obtained from sustainable resources at the same time. The combination of bio-fibers like betel nut, banana, coir, jute, rice straw, tea dust and various grasses with polymer matrices from both non-renewable (petroleum based) and renewable resources to produce composite materials that are competitive with synthetic composites such as glass fiber reinforced polypropylene or epoxide has been getting increased attention over the last decades. This article provides a general overview of natural fibers and bio-composites as well as the research on and application of these materials. A special emphasis is placed on surface modification of natural fibers to attain desired composite properties. The roles of compatibilizers and radiation on the natural fiber-polymer composites are also included. A discussion about chemical nature, processing, testing and properties of natural fiber reinforced polymer composites completes this article.

Keywords: Natural fiber, surface modification, compatibilizer, radiation, hybrid composite, mechanical properties

1.1 Introduction

The demand for natural fiber reinforced polymer composites is growing rapidly due to their high mechanical properties, significant processing advantages, low cost and low density. Natural fibers are renewable resources in many countries of the world; they are cheaper, pose no health hazards and finally provide a solution to environmental pollution by finding new uses over expensive materials and non-renewable resources. Furthermore, natural fiber reinforced polymer composites form a new class of materials which seem to have great potential in the future as a substitute for scarce wood and wood based materials in societal applications [1].

Lignocellulosic natural fibers like jute, sisal, coir, and pineapple have been used as reinforcements in polymer matrices. Natural fibers of vegetable origin include bast, leaves, and wood fibers. They may differ considerably in their physical appearance but they have, however, many similarities that identify them as one family. The characteristics of the fibers depend on the individual constituents and the fibrillar structure. The fiber is composed of numerous elongated fusiform fiber cells. The fiber cells are linked together by means of middle lamellae, which consist of hemicellulose, lignin and pectin. Growing environmental awar...
