Lignin is one of the most abundant plant-derived feedstock on earth
and qualifies as a renewable material. However, lignin is widely
recognized as waste byproduct of the cellulosic ethanol and pulp
and paper industry. How to properly modify lignin and develop it
into functional polymers is a huge challenge, but an attractive
research topic in both industry and academia.This book brings
together leading engineering approaches to address the challenges
of lignin valorization. It presents the chemistry and properties of
different types of lignin, and explores the cutting-edge approaches
of lignin modifications. Unlike any existing texts, this book not
only summarizes the traditional ways of using lignin, but also
presents various potential applications of lignin materials
together with advanced processing techniques.The basis of lignin
(its chemistry, types and properties) is described, as are
different approaches to modify it. The features of lignin and its
copolymers are explored and aligned with their potential
applications. In addition to the carbon materials from lignin, the
advanced fabrication approaches to engineer lignin-based
micro/nano-structural materials are summarized.
Polymers are one of the most versatile and important materials used
for capsule preparation despite various others available. Suitably
formulated capsules can securely protect ingredients, deliver them
to targeted sites, and release them expeditiously, improving
functions and minimizing adverse effects. New polymers are
constantly being explored to develop more efficient capsules as
they are routinely used in pharmaceuticals, consumer healthcare
products, nutrients, and food. This book focuses on the current
state of the art of polymer-based capsules and delivery systems. It
describes the formulation processes of capsules developed from
redox-responsive polymers and polymer-functionalized carbon
nanotubes, in addition to shedding light on coacervation of
polymers for encapsulation. It reviews different active ingredients
that can be used with polymer capsules in various products,
encapsulation of essential oils using such capsules, and
development of polymer capsules of cells and bacteriophages.

Biodegradable thermogels are a promising class of
stimuli-responsive polymers. This book summarizes recent
developments in thermogel research with a focus on synthesis and
self-assembly mechanisms, gel biodegradability, and applications
for drug delivery, cell encapsulation and tissue engineering. A
closing chapter on commercialisation shows the challenges faced
bringing this new material to market. Edited by leading authorities
on the subject, this book offers a comprehensive overview for
academics and professionals across polymer science, materials
science and biomedical and chemical engineering.
All aspects of the personal care industry will be comprehensively
discussed in Polymers for Personal Care Products and Cosmetics,
including biological targets, safety issues, and the legal and
regulatory aspects of this large industry. There will be a broad
overview of cosmetic ingredients, vehicles and finished products as
well as coverage of the main methodologies for microbiology, safety
and efficacy testing. The reader will be provided with a solid
background of the fundamentals of the area, before being brought up
to date on the future of this field, along with discussion of the
latest materials trends and future perspectives. Written by a World
renowned expert in the area, the book will provide a unique look
into this fast developing industry from interviews carried out with
key experts in industry and academia. The advantages and
disadvantages of the technologies involved in the development of
these materials will be highlighted, providing a balanced and
thorough review of the current state-of-the-art research. This book
will appeal to researchers, academics and students working in
polymer and materials chemistry, particularly those with an
interest in personal care products.
This book describes the development of "smart" biomaterials based
on the naturally derived poly- (R)-3-hydroxybutyrate](PHB). The
first part of this book focuses on biodegradable multiblock
thermoresponsive poly(ether ester urethane)s consisting of
poly(ethylene glycol) (PEG), poly(propylene glycol) (PPG) and PHB.
The physical properties as well as applicative studies of these
gels such as drug release and tissue engineering are presented. In
the second part, the preparation of novel thermoresponsive micelles
is presented. Using this copolymer, a thermoresponsive substrate
was fabricated by drop-coating with an aqueous polymer solution,
and used for the attachment and nonenzymatic temperature-induced
detachment of human mesenchymal stem cells and mouse embryonic stem
(ES) cells. The promising results from the studies show that these
copolymers could be utilized as surface modifiers for tissue
engineering applications. In summary, the synthesis of novel "smart
biomaterials" and their application in the fields of drug delivery
and tissue engineering are described in this book.
