This document summarizes a research project on modifying natural rubber latex for surgical gloves. The objectives were to disperse polyaniline (PANI) powder into latex to study the effects on mechanical and dispersion properties. PANI was synthesized and characterized, finding it flocculated with particle sizes of 88-260 microns. PANI was then added to latex solutions at different loadings and the mixtures were cast into films. Mechanical testing found the large PANI particles affected dispersion and inconsistent properties. Adding PANI would cost an estimated RM 0.46 per 100 gloves. In summary, the research aimed to add PANI to latex to potentially enhance glove properties but found the large polymer particles hindered consistent dispersion and mechanical performance.

RESEARCH OBJECTIVES
1. To prepare pure PANI powder and mixing
capabilities.
2. To disperse pure PANI template into latex
glove formulation.
3. To study the mechanical and dispersion
properties of the produced modified latex
film.
RESEARCH OVERVIEW
Surgical glove is a common thing used in
surgical operations. This surgical glove is
getting well developed day by day to produce a
safer and low risk of migration of
microorganisms between patient and surgeon
and vice versa. When foreign bodies implant in
a patient, the risk of microbial contamination of
the surgical site and the subsequent
development of SSI is increased.
Reported SSI levels associated with the
implantation of prosthetic devices range from
1%–20% with mesh implants for treating
hernias, 5%–41% with cerebrospinal fluid (CSF)
shunts, 25%–50% with the use of aortic balloon
pumps and 0.5%–2.0%.
